You might to configure error_reporting (see also), and enable the displaying of errors (see display_errors or ini_set) -- at least on your development machine

In your php.ini file, you'd use

error_reporting = E_ALL | E_STRICT
display_errors = On
html_errors = On

Or, in your PHP code :

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

You might also want to install Xdebug on your development box, to get nice stacktraces wehn an error / exception occurs

Of course, on your production machine, you probably don't want to display errors ; so that will have to be configured depending on your environment ;-)

Solution 2

It is almost certainly the case that display_errors is disabled in php.ini.

This is a good thing on product servers, and makes development systems basically unusable.

For a development system you probably want to add one of these lines to you php.ini file:

error_reporting  =  E_ALL & ~E_NOTICE

or

error_reporting  =  E_ALL

Solution 3

Create a file for example test.php with this content:

<?php
phpinfo();
?>

Execute it in your browser and search where the php.ini file is located. Than turn error reporting and displaying errors in php.ini on.

To add to this, you can probably find the errors in the webserver's log (for Apache, this is often /var/log/httpd/error_log)
