stream_set_timeout — Set timeout period on a stream
Description
$stream, int $seconds, int $microseconds = 0): bool
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.
Parameters
-
stream -
The target stream.
-
seconds -
The seconds part of the timeout to be set.
-
microseconds -
The microseconds part of the timeout to be set.
Return Values
Returns true on success or false on failure.
Examples
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;
}
}
?>
Notes
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.
