(PHP 4 >= 4.3.0)

stream_set_timeout -- Set timeout period on a stream


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

Sets the timeout value on stream, expressed in the sum of seconds and microseconds. 如果成功则返回 TRUE,失败则返回 FALSE

例子 1. stream_set_timeout() example

= fsockopen("", 80);
if (!
$fp) {
"Unable to open\n";
} else {
fputs($fp, "GET / HTTP/1.0\n\n");
stream_set_timeout($fp, 2);
$res = fread($fp, 2000);

注: 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 was previously called as set_socket_timeout() and later socket_set_timeout() but this usage is deprecated.
