Fatal error: Maximum execution time of 30 seconds exceeded

i have one pdf again sir, and the file size is 2.5 mb. I want to try pdf that have 100 page and i got this error. Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\regex\PdfToText.phpclass on line 142.
How to solve it?

Don't worry, this does not come from your pdf file nor does it come from the PdfToText class.

Actually, there is a setting called "max_execution_time" in your php.ini file whose default value is 30 (seconds).

Set it to a higher value, 120 for example. This will give your script 4 minutes to execute, which should be enough.

Note : you must restart Apache for your modification to take effect.

If 120 is not enough, try a higher value.

Hope this helps !
