For my development environment I recently moved to PHP 5.3 w/ fastCGI on IIS from php 5.2 w/ ISAPI on IIS and when I have an error (such as function name is incorrect) I'm used to PHP reporting back FATAL ERROR etc... to the browser. Intermittently instead of receiving the error I receive a HTTP 500. If browsing with firefox this does not occur.
It seems to be related to IE caching content-type or HTTP code something like that. My reasoning is that if I eliminate the chunk of offending code and refresh the page (in IE) and then place the offending code back in I will see the error message.
Does anyone know what I should look at?
display_errors is set to On....
Tried to add code in comments and it was ugly so i'm appending:
Sample Code:
index.php
<?php
php_infowrong();
?>
If I type in the URL of the website I get:
On Firefox I receive: PHP Fatal error: Call to undefined function php_infowrong() in D:\Web\pathtowebsite\index.php on line 2
On Internet Explorer I receive: HTTP 500 Internal Server Error
If I then change the index.php to
<?php
phpinfo();
?>
Then both IE and Firefox give the correct php_info page.
If I change the index.php back to it's original erronous form and refresh the page THEN IE will show: PHP Fatal error: Call to undefined function php_infowrong() in D:\Web\pathtowebsite\index.php
