PHP fails silently when function not defined?

Question

I am migrating from PHP4 to PHP5

I have this in my .htaccess:

php_flag display_errors on
php_value error_reporting 2039

Which used to show all errors.

I am still getting some errors but I used to get an error when I called a function that was not defined, but now it stops where it is at and send the client everything up to the error and nothing after. With no error message.

Here is what phpinfo is telling me:

Directive   Local Value Master Value
display_errors  On  Off
error_reporting 2039    6143

I would like to be able to see my error messages for trouble shooting purposes.

Can someone tell me what I need to do? Thanks!!

Answer 1

If everything fails, just put this code at the beginning of your (/of each) script:

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

Answer 2

This should show you all messages:

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

Answer 3

I'd guess that you PHP 5 version is >= PHP 5.2.0 and that the original error reporting level was E_ALL & ~E_NOTICE (or E_ALL ^ E_NOTICE, both have the same result).

Prior to PHP 5.2.0 E_ALL had a value of 2047, so your error level was 2039 due to not including the E_NOTICE level (of 8). As of PHP 5.2.0 E_ALL changed to 6143 (and as of PHP 5.3.0 to 30719) which means E_ALL & ~E_NOTICE is no longer 2039, but rather 6135 (or 30711 in PHP 5.3).

As for not displaying the errors (calling an undefined function should be a fatal error!), see the other answers.
