string http_build_url([mixed url[, mixed parts[, int flags = HTTP_URL_REPLACE[, array &new_url]]]])

Build an URL.

Expexts (part(s) of) an URL as first parameter in form of a string or assoziative array
like parse_url() returns. Accepts an optional second parameter in the same way as the
first argument. Accepts an optional third integer parameter, which is a bitmask of
binary or'ed HTTP_URL_* constants. The optional fourth parameter will be filled
with the results as associative array like parse_url() would return.

The parts of the second URL will be merged into the first according to the flags argument.
The following flags are recognized:

	- HTTP_URL_REPLACE:        (default) set parts of the second url will replace the parts in the first
- HTTP_URL_JOIN_PATH: the path of the second url will be merged into the one of the first
- HTTP_URL_JOIN_QUERY: the two querystrings will be merged recursively
- HTTP_URL_STRIP_USER: the user part will not appear in the result
- HTTP_URL_STRIP_PASS: the password part will not appear in the result
- HTTP_URL_STRIP_AUTH: neither the user nor the password part will appear in the result
- HTTP_URL_STRIP_PORT: no explicit port will be set in the result
- HTTP_URL_STRIP_PATH: the path part will not appear in the result
- HTTP_URL_STRIP_QUERY: no query string will be present in the result
- HTTP_URL_STRIP_FRAGMENT: no fragment will be present in the result

Example:


<?php
        
// ftp://ftp.example.com/pub/files/current/?a=b&a=c
        
echo http_build_url("http://user@www.example.com/pub/index.php?a=b#files",

string http_negotiate_language(array supported[, array &result])

This function negotiates the clients preferred language based on its
Accept-Language HTTP header. The qualifier is recognized and languages

include 
'./langs/'http_negotiate_language($langs$result) .'.php';

print_r($result);
?>

string http_negotiate_charset(array supported[, array &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 containing the supported charsets as values.
If the optional second parameter is supplied, it will be filled with an
array containing the negotiation results.

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);
?>

string http_negotiate_ctype(array supported[, array &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 containing 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.

?>

bool http_send_status(int status)

Send HTTP status code.

Expects an HTTP status code as parameter.

Returns TRUE on success or FALSE on failure.

bool http_send_last_modified([int timestamp])

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.

bool http_send_content_type([string content_type = 'application/x-octetstream'])

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.

bool http_send_content_disposition(string filename[, bool inline = false])

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..." dialog
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.

bool http_match_modified([int timestamp[, bool for_range = false]])

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.

bool http_match_etag(string etag[, bool for_range = 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.

Returns TRUE if ETag matches or the header contained the asterisk ("*"),
else FALSE.

bool http_cache_last_modified([int timestamp_or_expires]])

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.log.cache is set and the cache attempt was successful.

bool http_cache_etag([string etag])

Attempts to cache the sent entity by its ETag, either supplied or generated
by the hash algorithm 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.log.cache" is set and the cache attempt was successful.

string ob_etaghandler(string data, int mode)

For use with ob_start(). Output buffer handler generating an ETag with
the hash algorithm specified with the INI setting "http.etag.mode".

void http_throttle(double sec[, int bytes = 40960])

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.

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');
?>

void http_redirect([string url[, array params[, bool session = false[, int status = 302]]]])

Redirect to the given url.

The supplied url will be expanded with http_build_url(), 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 for GET/HEAD, else 303 See Other
- HTTP_REDIRECT_PERM 301 Moved Permanently
- HTTP_REDIRECT_FOUND 302 Found
- HTTP_REDIRECT_POST 303 See Other
- HTTP_REDIRECT_PROXY 305 Use Proxy
- 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 URL." will be displayed,
if the client doesn't redirect immediately, 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.log.redirect" is set and the redirect attempt was successful.
