stream_set_timeout
(PHP 4 >= 4.3.0, PHP 5)
stream_set_timeout — Set timeout period on a stream
Description
bool stream_set_timeout
( resource $stream
, int $seconds
[, int $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.
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:
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.
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.
