The most annoying thing on my plate at the moment is what I've come to term "PHP's white screen php display errors off of death". When PHP gets a fatal error due to syntax or whatever, it seems like it will always die without actually sending anything to the browser. I've added the following to my .htaccess, and it seems to work most of the time, but it doesn't work in these cases. php_value display_errors 1 php_value display_startup_errors 1 php_value error_reporting 2147483647 # E_ALL Am I missing something? At the moment I feel like I need to hit refresh every few lines of code I write, lest I make a mistake and have to search through many pages trying to track down that one little mistake I made... EDIT: For example, given the two lines of code below: $foo = array(':language' => $languageId; $foo = array(':language' => $languageId); The first will exhibit the white screen of death (ie, nothing at all printed to the browser), while the second will execute happily. php error-handling error-reporting wsod share|improve this question edited Dec 10 '12 at 5:23 hakre 134k26216390 asked Sep 25 '09 at 3:36 Matthew Scharley 61.6k39151197 Also see s

UPDATE 1: I have changed error_reporting in php.ini from: error_reporting = E_ALL & ~E_DEPRECATED to error_reporting = E_ALL | E_STRICT After which I restarted apache, e.g. /etc/init.d/apache2 restart But the page will still not display errors/warnings of any kind. ORIGINAL QUESTION: The following script is generating an warning because the $err being inside the if statement. Why is this warning not being displayed on the php page in a web browser? I have to look at apache logs to see the warning. Also, if I delibarately change the "insert into" to "delete into", it does not display an error on the php page. Why are the errors not displaying on the actual php page?

This works though. :) –Citricguy Feb 3 '12 at 5:25 add a comment| up vote 16 down vote The White Screen of Death (Completely Blank Page) resource on drupal.org will step you through the steps to see the error message as well as common problems that cause them. "Invisible" Errors If error reporting is turned off, you could be getting a fatal error but not seeing it. On a production site, it is common to have error reporting turned off. If that is the case and PHP has hit an unrecoverable error, neither an error nor content will be displayed, therefore you end up with a completely blank page. What you can do about this is either turn on PHP error reporting so it displays a message on the page itself, or check your log files (from the server) to look for the error. How to do both of these are explained below. Enable Error Repor

Some errors are only reported when all PHP error reporting is switched on. Without the error reporting on, you get the dreaded White Screen of Death. Check for errors behind the scenes As an alternative between showing no errors and showing all errors, you may wish to monitor the errors being generated by your site by running tail -f /var/log/apache2/error.log on your server. Change settings in your dev site You can show all errors by adding a few lines to your local testing site's settings.php: error_reporting(E_ALL); ini_set('display_errors', TRUE); ini_set('display_startup_errors', TRUE); In addition, navigate to Administration→ Configuration→ Development → logging and errors and select "All messages".
