Solving the PHP Warning: fsockopen(): unable to connect (Connection timed out)

If you’ve worked with APIs you’ve probably gotten this error and know how annoying it is. All because the native function never returns any actionable error for its request timing out. The best way to detect if the fsockopen() function request is timing out is to use a error control operator. The idea is to suppress the timeout warning with a @ prefix, so the function only returns true if it completes its cycle/request. You can review the example PHP code below.

if($fp = @fsockopen($host, $port, $errno, $errstr, $timeout)) {   

return true;

return false;
