在PHP中设置套接字超时

Question

I'm writing a script in PHP that uses PEAR's Net_Socket. I want to query servers to see if they have any current information. I send in a command and then use $socket->readLine() to get the response. However, if there is not a response, my script just waits forever. Is there anyway to either tell the socket to close after a specific amount of time or to wrap the whole function in a timeout, that if it hasn't returned by the timeout, it halts its execution?

Answer 1

On the same page you linked is a link to setTimeout(): https://pear.php.net/manual/en/package.networking.net-socket.settimeout.php

Trying calling $socket->setTimeout( $seconds, $milliseconds ); just before calling readLine()
