Apache ErrorDocument not working for PHP 500 error

I have a number of ErrorDocuments setup in my .htaccess file for errors such as 404, 401, 403 etc which all redirect to my error page but the ErrorDocument set for a 500 error is never displayed when PHP reports a 500. The 500 code is sent to the browser and the output is blank. Is there something special I need to do to enable 500 error documents for use with PHP?

My directives look like this:

ErrorDocument 401 /errorpage.php?error=401
ErrorDocument 403 /errorpage.php?error=403
ErrorDocument 404 /errorp开发者_开发问答age.php?error=404
ErrorDocument 500 /errorpage.php?error=500

I've looked through the php.ini and can't see anything that would obviously override the Apache settings and there are no ErrorDocument directives in my httpd.conf either. Anywhere else I should be looking?

Thanks in advance.

See this answer to a very similar question. Basically, PHP isn't hardly ever going to trigger a 500.

You may need to add the ErrorDocument declaration earlier in the Apache conf chain. If you add this to a vhost conf it may not be called.

I happened to encounter the same issue while working with codeigniter and Imagick. imagick was setting a 500 HTTP error when something went wrong and in that case Codeigniter's custom 500 message was not displayed.

I resolved this by adding try-catch to all Imagick functions.Check that where from the 500 issue is arising and then add a try-catch there.As for

 ErrorDocument 500 /errorpage.php?error=500

,I read loads online about the same where some people claim that this solved their similar issue, others say that it wouldnt help as Apache has handed over the control to PHP.Maybe some php code is setting Headers to 500 and that would probably lead to the browser displaying its custom 500 error message.

I don't believe Apache will let you run PHP files for 500 errors because the error page could generate an error. Try rendering out your 500 error to an HTML file and point your directives at that.
