Preventing warnings from fsockopen

Question

I use fsockopen() to connect to multiple servers in a loop.

However some servers are not valid and I get PHP warnings like the one below:

Warning: fs         


        

Answer 1

Use the error control operator and check the results of fsockopen() to verfiy you have a valid connection.

$rc = @fsockopen(...);
if (is_resource($rc))
{
   // do work
}
