I developed a Sales Management System its is a stand alone system, i installed in the Pc at first when it had few data it was working finely.
Then when data increased it started to be slow in its excution taking some seconds to complete the excution, eventually it was totally failing/timing out to complete the excution by returning back this message "Fatal error: Maximum execution time of 60 seconds exceeded in C:\xampp\htdocs\pharm\Admin\sale2.php on line 58".
By the way i have no idea what is the problem,,
So i need a help from you guys for any one who know where is the problem and how it can be overcomed.
The System by now is totally not working due to that,,
