Question

Typically I use E_ALL to see anything that PHP might say about my code to try and improve it.

Use the following in php.ini:

Also you should install Xdebug, it can highlight your errors in blinding bright colors and print useful detailed information.

Never let any error or notice in your code, even if it's harmless.
