PHP脚本，错误导致空白页

Question

I have a php script with a few errors in. It's impossible to debug since its not showing me the errors!!

I tried:

my first line in my script contains following:

   <?php  ini_set('display_errors',1); error_reporting(E_ALL); ?>

but its still not giving me any errors, anyone?

there are numerous php.ini files, how do I know which one is the one I need to edit?

Answer 1

If you are hosted somewhere (meaning you do not own and operate the server), contact thier support and have them add

display_errors = On

to the php.ini file. Then you can use

error_reporting(E_ALL);
ini_set('display_errors', '1');

If you are running it yourself, simply make the changes and give it a try.
