How to disable errors for FSOCKOPEN

Hi, today I want to share with you a little tip on the FSOCKOPEN function.You know that when fsockopen function fails on php it always gives you a warning like this:

Warning: fsockopen(): unable to connect to (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ) in E:\xampp\htdocs\test.php on line 2

You can simply block only the fsockopen function warnings/ notices or another errors from that line of the code by simply adding “@” symbol in the front of the variable or function, like this:

@$fp = fsockopen(“”,”8440″,$errno,$errstr,5);

or like this:

$fp = @fsockopen(“”,”8440″,$errno,$errstr,5);

Hope this helps you, thanks for reading my tutorial.
