stream_set_timeout — Set timeout period on a stream
$stream
, int $seconds
[, int $microseconds = 0
] )
Sets the timeout value on stream,
expressed in the sum of seconds and
microseconds.
When the stream times out, the 'timed_out' key of the array returned by
stream_get_meta_data() is set to TRUE, although no
error/warning is generated.
streamThe target stream.
secondsThe seconds part of the timeout to be set.
microsecondsThe microseconds part of the timeout to be set.
Returns TRUE on success or FALSE on failure.
| Version | Description |
|---|---|
| 4.3.0 | As of PHP 4.3, this function can (potentially) work on any kind of stream. In PHP 4.3, socket based streams are still the only kind supported in the PHP core, although streams from other extensions may support this function. |
Example #1 stream_set_timeout() example
<?php
$fp = fsockopen("www.example.com", 80);
if (!$fp) {
echo "Unable to open\n";
} else {
fwrite($fp, "GET / HTTP/1.0\r\n\r\n");
stream_set_timeout($fp, 2);
$res = fread($fp, 2000);
$info = stream_get_meta_data($fp);
fclose($fp);
if ($info['timed_out']) {
echo 'Connection timed out!';
} else {
echo $res;
}
}
?>
Note:
This function doesn't work with advanced operations like stream_socket_recvfrom(), use stream_select() with timeout parameter instead.
This function was previously called as set_socket_timeout() and later socket_set_timeout() but this usage is deprecated.
