Compose a valid HTTP date regarding RFC 822/1123
looking like: "Wed, 22 Dec 2004 11:34:47 GMT"
Takes an optional unix timestamp as parameter.
Returns the HTTP date as string.
Build a complete URI according to the supplied parameters.
If the url is already abolute but a different proto was supplied,
only the proto part of the URI will be updated. If url has no
path specified, the path of the current REQUEST_URI will be taken.
The host will be taken either from the Host HTTP header of the client
the SERVER_NAME or just localhost if prior are not available.
If a port is pecified in either the url or as sperate parameter,
it will be added if it differs from te default port for HTTP(S).

This function negotiates the clients preferred language based on its
Accept-Language HTTP header. The qualifier is recognized and languages
without qualifier are rated highest. The qualifier will be decreased by
10% for partial matches (i.e. matching primary language).
Expects an array as parameter cotaining the supported languages as values.
If the optional second parameter is supplied, it will be filled with an
array containing the negotiation results.
Returns the negotiated language or the default language (i.e. first array entry)
if none match.
Example:
<?php
$langs = array(
'en-US',// default
'fr',
'fr-FR',
'de',
'de-DE',
'de-AT',
'de-CH',
);
include './langs/'. http_negotiate_language($langs, $result) .'.php';
print_r($result);
?>
This function negotiates the clients preferred charset based on its
Accept-Charset HTTP header. The qualifier is recognized and charsets
without qualifier are rated highest.
Expects an array as parameter cotaining the supported charsets as values.
If the optional second parameter is supplied, it will be filled with an
array containing the negotiation results.
Returns the negotiated charset or the default charset (i.e. first array entry)
if none match.
Example:
<?php
$charsets = array(
'iso-8859-1', // default
'iso-8859-2',
'iso-8859-15',
'utf-8'
);
$pref = http_negotiate_charset($charsets, $result);
if (strcmp($pref, 'iso-8859-1')) {
iconv_set_encoding('internal_encoding', 'iso-8859-1');
iconv_set_encoding('output_encoding', $pref);
ob_start('ob_iconv_handler');
}
print_r($result);
?>
This function negotiates the clients preferred content type based on its
Accept HTTP header. The qualifier is recognized and content types
without qualifier are rated highest.
Expects an array as parameter cotaining the supported content types as values.
If the optional second parameter is supplied, it will be filled with an
array containing the negotiation results.
Returns the negotiated content type or the default content type
(i.e. first array entry) if none match.
Example:
<?php
$ctypes = array('application/xhtml+xml', 'text/html');

?>
Send HTTP status code.
Expects an HTTP status code as parameter.
Returns TRUE on success or FALSE on failure.
Send a "Last-Modified" header with a valid HTTP date.
Accepts a unix timestamp, converts it to a valid HTTP date and
sends it as "Last-Modified" HTTP header. If timestamp is
omitted, the current time will be sent.
Returns TRUE on success or FALSE on failure.
Send the Content-Type of the sent entity. This is particularly important
if you use the http_send() API.
Accepts an optional string parameter containing the desired content type
(primary/secondary).
Returns TRUE on success or FALSE on failure.
Send the Content-Disposition. The Content-Disposition header is very useful
if the data actually sent came from a file or something similar, that should
be "saved" by the client/user (i.e. by browsers "Save as..." popup window).
Expects a string parameter specifying the file name the "Save as..." dialogue
should display. Optionally accepts a bool parameter, which, if set to true
and the user agent knows how to handle the content type, will probably not
cause the popup window to be shown.
Returns TRUE on success or FALSE on failure.
Matches the given unix timestamp against the clients "If-Modified-Since"
resp. "If-Unmodified-Since" HTTP headers.
Accepts a unix timestamp which should be matched. Optionally accepts an
additional bool parameter, which if set to true will check the header
usually used to validate HTTP ranges. If timestamp is omitted, the
current time will be used.
Returns TRUE if timestamp represents an earlier date than the header,
else FALSE.
Matches the given ETag against the clients "If-Match" resp.
"If-None-Match" HTTP headers.
Expects a string parameter containing the ETag to compare. Optionally
accepts a bool parameter, which, if set to true, will check the header
usually used to validate HTTP ranges.
Retuns TRUE if ETag matches or the header contained the asterisk ("*"),
else FALSE.
Attempts to cache the sent entity by its last modification date.
Accepts a unix timestamp as parameter which is handled as follows:
If timestamp_or_expires is greater than 0, it is handled as timestamp
and will be sent as date of last modification. If it is 0 or omitted,
the current time will be sent as Last-Modified date. If it's negative,
it is handled as expiration time in seconds, which means that if the
requested last modification date is not between the calculated timespan,
the Last-Modified header is updated and the actual body will be sent.
Returns FALSE on failure, or *exits* with "304 Not Modified" if the entity is cached.
A log entry will be written to the cache log if the INI entry
http.cache_log is set and the cache attempt was successful.
Attempts to cache the sent entity by its ETag, either supplied or generated
by the hash algorythm specified by the INI setting "http.etag_mode".
If the clients "If-None-Match" header matches the supplied/calculated
ETag, the body is considered cached on the clients side and
a "304 Not Modified" status code is issued.
Returns FALSE on failure, or *exits* with "304 Not Modified" if the entity is cached.
A log entry is written to the cache log if the INI entry
"http.cache_log" is set and the cache attempt was successful.
For use with ob_start(). Output buffer handler generating an ETag with
the hash algorythm specified with the INI setting "http.etag_mode".
Sets the throttle delay and send buffer size for use with http_send() API.
Provides a basic throttling mechanism, which will yield the current process
resp. thread until the entity has been completely sent, though.
Note: This doesn't really work with the FastCGI SAPI.
Expects a double parameter specifying the seconds too sleep() after
each chunk sent. Additionally accepts an optional int parameter
representing the chunk size in bytes.
Example:
<?php
// ~ 20 kbyte/s
# http_throttle(1, 20000);
# http_throttle(0.5, 10000);
# http_throttle(0.1, 2000);
http_send_file('document.pdf');
?>
Redirect to the given url.
The supplied url will be expanded with http_build_uri(), the params array will
be treated with http_build_query() and the session identification will be appended
if session is true.
The HTTP response code will be set according to status.
You can use one of the following constants for convenience:
- HTTP_REDIRECT 302 Found
- HTTP_REDIRECT_PERM 301 Moved Permanently
- HTTP_REDIRECT_POST 303 See Other
- HTTP_REDIRECT_TEMP 307 Temporary Redirect
Please see http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3
for which redirect response code to use in which situation.
To be RFC compliant, "Redirecting to URI." will be displayed,
if the client doesn't redirect immediatly, and the request method was
another one than HEAD.
Returns FALSE on failure, or *exits* on success.
A log entry will be written to the redirect log, if the INI entry
"http.redirect_log" is set and the redirect attempt was successful.

Instantiate a new HttpRequestPool object. An HttpRequestPool is
able to send several HttpRequests in parallel.
WARNING: Don't attach/detach HttpRequest objects to the HttpRequestPool
object while you're using the implemented Iterator interface.
Accepts virtual infinite optional parameters each referencing an
HttpRequest object.
Throws HttpRequestPoolException (HttpRequestException, HttpInvalidParamException).
Example:
<?php
try {
$pool = new HttpRequestPool(
new HttpRequest('http://www.google.com/', HttpRequest::METH_HEAD),
new HttpRequest('http://www.php.net/', HttpRequest::METH_HEAD)
);
$pool->send();
foreach($pool as $request) {
printf("%s is %s (%d)\n",
$request->getUrl(),
$request->getResponseCode() ? 'alive' : 'not alive',
$request->getResponseCode()
);
}
} catch (HttpException $e) {
echo $e;
}
?>
Clean up HttpRequestPool object.

WARNING: set all options prior attaching!
Expects the parameter to be an HttpRequest object not alread attached to
antother HttpRequestPool object.
Returns TRUE on success, or FALSE on failure.
Throws HttpInvalidParamException, HttpRequestException,
HttpRequestPoolException, HttpEncodingException.

Usage:
<?php
class MyPool extends HttpRequestPool
{
public function send()
{
while ($this->socketPerform()) {
if (!$this->socketSelect()) {
throw new HttpSocketExcpetion;
}
}
}
protected final function socketPerform()
{
$result = parent::socketPerform();
foreach ($this->getFinishedRequests() as $r) {
$this->detach($r);
// handle response of finished request
}
return $result;
}
}
?>
See HttpRequestPool::socketPerform().
Returns TRUE on success, or FALSE on failure.
Implements Iterator::valid().
Implements Iterator::current().
Implements Iterator::key().
Implements Iterator::next().
Implements Iterator::rewind().
Implements Countable.
Returns the number of attached HttpRequest objects.
Get attached HttpRequest objects.
Returns an array containing all currently attached HttpRequest objects.
Get attached HttpRequest objects that already have finished their work.
Returns an array containing all attached HttpRequest objects that
already have finished their work.
Send an HTTP header.
Expects a string parameter containing the name of the header and a mixed
parameter containing the value of the header, which will be converted to
a string. Additionally accepts an optional boolean parameter, which
specifies whether an existing header should be replaced. If the second
parameter is unset no header with this name will be sent.
Returns TRUE on success, or FALSE on failure.
Throws HttpHeaderException if http.only_exceptions is TRUE.
Get header(s) about to be sent.
Accepts a string as optional parameter which specifies the name of the
header to read. If the parameter is empty or omitted, an associative array
with all headers will be returned.
Returns either a string containing the value of the header matching name,
FALSE on failure, or an associative array with all headers.
Whether it sould be attempted to cache the entitity.
This will result in necessary caching headers and checks of clients
"If-Modified-Since" and "If-None-Match" headers. If one of those headers
matches a "304 Not Modified" status code will be issued.
NOTE: If you're using sessions, be shure that you set session.cache_limiter
to something more appropriate than "no-cache"!
Expects a boolean as parameter specifying whether caching should be attempted.
Returns TRUE ons success, or FALSE on failure.
Get current caching setting.
Returns TRUE if caching should be attempted, else FALSE.
Enable on-thy-fly gzipping of the sent entity.
Expects a boolean as parameter indicating if GZip compression should be enabled.
Returns TRUE on success, or FALSE on failure.
Get current gzipping setting.
Returns TRUE if GZip compression is enabled, else FALSE.
Set a custom cache-control header, usually being "private" or "public";
The max_age parameter controls how long the cache entry is valid on the client side.
Expects a string parameter containing the primary cache control setting.
Addtitionally accepts an int parameter specifying the max-age setting.
Returns TRUE on success, or FALSE if control does not match one of
"public" , "private" or "no-cache".
Throws HttpInvalidParamException if http.only_exceptions is TRUE.
Get current Cache-Control header setting.
Returns the current cache control setting as a string like sent in a header.
Set the content-type of the sent entity.
Expects a string as parameter specifying the content type of the sent entity.
Returns TRUE on success, or FALSE if the content type does not seem to
contain a primary and secondary content type part.
Throws HttpInvalidParamException if http.only_exceptions is TRUE.
Get current Content-Type header setting.
Returns the currently set content type as string.
Attempts to guess the content type of supplied payload through libmagic.
If the attempt is successful, the guessed content type will automatically
be set as response content type.
Expects a string parameter specifying the magic.mime database to use.
Additionally accepts an optional int parameter, being flags for libmagic.
Returns the guessed content type on success, or FALSE on failure.
Throws HttpRuntimeException, HttpInvalidParamException
if http.only_exceptions is TRUE.
Set the Content-Disposition. The Content-Disposition header is very useful
if the data actually sent came from a file or something similar, that should
be "saved" by the client/user (i.e. by browsers "Save as..." popup window).
Expects a string parameter specifying the file name the "Save as..." dialogue
should display. Optionally accepts a bool parameter, which, if set to true
and the user agent knows how to handle the content type, will probably not
cause the popup window to be shown.
Returns TRUE on success or FALSE on failure.
Get current Content-Disposition setting.
Returns the current content disposition as string like sent in a header.
Set a custom ETag. Use this only if you know what you're doing.
Expects an unquoted string as parameter containing the ETag.
Returns TRUE on success, or FALSE on failure.
Get calculated or previously set custom ETag.
Returns the calculated or previously set ETag as unquoted string.

time of the sent entity.
Returns TRUE on success, or FALSE on failure.
Get calculated or previously set custom Last-Modified date.
Returns the calculated or previously set unix timestamp.
Sets the throttle delay for use with HttpResponse::setBufferSize().
Provides a basic throttling mechanism, which will yield the current process
resp. thread until the entity has been completely sent, though.
Note: This doesn't really work with the FastCGI SAPI.
Expects a double parameter specifying the seconds too sleep() after
each chunk sent.
Returns TRUE on success, or FALSE on failure.
Get the current throttle delay.
Returns a double representing the throttle delay in seconds.
Sets the send buffer size for use with HttpResponse::setThrottleDelay().
Provides a basic throttling mechanism, which will yield the current process
resp. thread until the entity has been completely sent, though.
Note: This doesn't really work with the FastCGI SAPI.
Expects an int parameter representing the chunk size in bytes.
Returns TRUE on success, or FALSE on failure.
Get current buffer size.
Returns an int representing the current buffer size in bytes.
Set the data to be sent.
Expects one parameter, which will be converted to a string and contains
the data to send.
Returns TRUE on success, or FALSE on failure.
Get the previously set data to be sent.
Returns a string containing the previously set data to send.
Set the resource to be sent.
Expects a resource parameter referencing an already opened stream from
which the data to send will be read.
Returns TRUE on success, or FALSE on failure.
Get the previously set resource to be sent.
Returns the previously set resource.

Expects a string as parameter, specifying the path to the file to send.
Returns TRUE on success, or FALSE on failure.
Get the previously set file to be sent.
Returns the previously set path to the file to send as string.
Finally send the entity.
Accepts an optional boolean parameter, specifying wheter the ouput
buffers should be discarded prior sending. A successful caching attempt
will cause a script termination, and write a log entry if the INI setting
http.cache_log is set.
Returns TRUE on success, or FALSE on failure.
Throws HttpHeaderException, HttpResponseException if http.onyl_excpetions is TRUE.
Example:
<?php
HttpResponse::setCache(true);
HttpResponse::setContentType('application/pdf');
HttpResponse::setContentDisposition("$user.pdf", false);
HttpResponse::setFile('sheet.pdf');
HttpResponse::send();
?>
