Max Execution Time Exceeds In A Call To A Function Of A Class

[sagnik]

I've a class named "SGSocial". I'm sending data by ajax to a file and calling to a function of SGSocial from the file. But the problem is, ajax takes too much time to retrieve data. And PHP gives "Fatal error: Maximum execution_time exceeds in sgsspl.php on line 399" . Here is the link to all the files related to the problem: https://www.dropbox.com/sh/1pf51ff5zmohqi9/AADDiRDV2pgdCBm8o0FJ8EMEa?dl=0

Can anyone help me to figure out the problem??
