Turning on display_errors in WAMP - Video Tutorial
Hi,
Within a WAMP installation, I ran into a little issue today when trying to change php.ini’s ‘display_errors’ property.
By default WAMP installs with ‘display_errors’ to ‘Off’:
display_errors = Off
… This is a pain-in-the-ass setting when trying to write new PHP code because errors don’t get displayed in the browser window; you have to go to the log file.
So like any good nerd, I popped open php.ini and made the change:
display_errors = On
Problem is that it didn’t work. I soon discovered that WAMP was using ANOTHER php.ini file on my machine!
Solution:
Run phpinfo() and look for the property: ‘Loaded Configuration File’
This will tell you what php.ini WAMP is using.
-
I created a video (with more details on WAMP and php.ini) for those who like to watch.
Thanks,

Good cast.
I think it’s important to mention that display_errors should only be set to ‘on’ under development servers and should always be ‘off’ under production.
Also, display_errors will not show parse errors by default. If you want PHP to render parse errors on your development server, you’ll need to set the error_reporting directive to an appropriate level.
I personally find it easier to leave them both set to the default, secure setting as they are shipped with PHP. When in development, I include a ‘development.php’ file which has the following content.
Cheers,

I guess you set wordpress to not render anything within brackets… The content for the file is as follows:
ini_set(’display_errors’, ‘on’);
error_reporting(E_ALL);

“I think it’s important to mention that display_errors should only be set to ‘on’ under development servers and should always be ‘off’ under production.”
Agreed.
