[SOLVED] Debugging: stop if variable undefined

[KenDRhyD]

I am developing on Mac OS 10.5.5 with all of the latest patches.

 

Some time ago when I was developing some PHP code for a web site on my iMac the code would report an error and fail the page if my PHP code referenced a variable that did not exist. This was great since it allowed me to find typing errors.

 

Since then I have upgraded my system several times, and now any reference to a non-existent variable simply results in a null value -- which makes it much more difficult to locate such problems.

 

How can I enable, either permanently, temporarily or per execution the debug mode where references to undefined variables results in a fatal error?

it's in the E_STRICT setting (which I also love!). You can just do

error_reporting('E_ALL | E_STRICT');

 

But if you want it for every page in a non-production environment I'd do it in php.ini.

For errors to be displayed during runtime you'll also need to to make display_errors is enabled.

 

You can set this within your php.ini

display_errors = On

 

Or via ini_set in your scripts

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

I think he was just referring to the "undefined variable" errors and "undefined offset" errors for arrays, which is in E_STRICT and not included in E_ALL.

Or via ini_set in your scripts

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

 

Does the ini_set() function permanently change the contents of the php.ini file, or does the change only last for the remainder of the page or the session?

The script execution unless changed further on.

This is handled by E_ALL for me.
