stream_set_timeout

]Podporované v PHP 4 >= 4.3.0, PHP 5

Syntax

bool stream_set_timeout ( resource $stream , int $seconds [, int $microseconds ] )

Popis

Príkaz jazyka PHP
Set timeout period on a stream.
Sets the timeout value on stream , expressed in the sum of seconds and microseconds. Returns TRUE on success or FALSE on failure.

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.

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.

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.

Príklad

<?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;
}

}
?>
