  ZendCore+FastCGI+IIS7 : Cannot embed PHP errors in response HTML. Always get 500 - Internal server error Reply Contact Hello, I am running WS2008 + IIS7 + FASTCGI + ZendCore. I have not modified the default ZendCore php.ini configuration file. Actualy, any kind of PHP error, warning or notice gives me immediately a IIS 500 Error (Internal Server Error). It is a good thing in production environnement. For debuging purposes, I want temporary to be able to see PHP warnings and errors embedded on the html page. So I have set "display_errors = On" on the ZC admin panel. But nothing changes ... I still always got error 500 on pages containing errors, warning, or notice. But I found that if I go to the website I want to debug using http://localhost/mypage.php (so direclty on a browser on the production server), I got the PHP errors embedded in the html page. But when using the ip of the server, or the host header, I got error 500. I also tried using ISAPI instead of FastCGI. The problem is still quite the same, but in that case, only parse errors or undefined functions gives me Error 500. Notices and Warning are well embedded. Here is the IIS error log when getting an Internal Server Error (testPage is a test page containing a division by Zero Warning). -------------------------------------- MODULE_WARNING ModuleName FastCgiModule Data1 FASTCGI_RESPONSE_ERROR Data2 PHP Warning:  Division by zero in C:\inetpub\wwwroot\Catalogues \testPage.php on line 6 ErrorCode 5 ErrorCode Access is denied. (0x5) MODULE_SET_RESPONSE_ERROR_STATUS ModuleName FastCgiModule Notification 128 HttpStatus 500 HttpReason Internal Server Error HttpSubStatus 0 ErrorCode 0 ConfigExceptionInfo Notification EXECUTE_REQUEST_HANDLER ErrorCode The operation completed successfully. (0x0) -------------------------------------- My php test page is as easy as : <?php $data = 0/0; ?> I would like "PHP Warning:  Division by zero in C:\inetpub\wwwroot \Catalogues " beeing printed on the return page ... Instead of it, I got 500 error, even with display_errors=On. I also tried to process the test page directly on a console (using "php -f mypage.php"), and the warning is well printed in the console. So the problem seems not to come from the php interperter. Zend is in a full default configuration state. The only param I have changed is the display_errors config. I tried also with PHP manualy installed from the official Non thread safe binaries (so without the zend package). The problem is exacly the same ... The website is running in a unmanaged IIS appPool with Network Serivce identity. There is maybe a right access problem somewhere (as the error log talks about an Access Denied error...). But where ? The PHP binary path ? The website path ? ... No ideas. But as  the website works perfecly in production, I don't think it deals with that ... The strangest thing in my problem is that errors are well printed when browsing using http://localhost/... directly on the production server ... But got 500 error when using http://192.168.1.1/... (the server IP). Do anybody got an idea on how to get full PHP error reporing into the HTML page with IIS7, FastCGI and Zend Core ? Thanks, Guillaume

  Re: ZendCore+FastCGI+IIS7 : Cannot embed PHP errors in response HTML. Always get 500 - Internal server error Reply Contact You would need to set system.webServer/httpErrors/errorMode to Detailed to do this - default is DetailedLocalOnly so as not to expose extra information to remote clients.  The following appcmd command will achieve that. %windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpErrors -errorMode:Detailed Anil Ruia Senior Software Design Engineer IIS Core Server

  Re: ZendCore+FastCGI+IIS7 : Cannot embed PHP errors in response HTML. Always get 500 - Internal server error Reply Contact I'm having the same problem too. Setting Detailed error reports doesn't help because you don't see the error messages PHP generated (just a page with details on FastCGI). How do you get the raw output from PHP without any IIS7 fancy error pages? It's like IIS is intercepting any response with code 500 and putting its own page in its place.   EDIT: I'm actually wrong a bit, when I force a divide-by-zero error it displays fine. It's an installation of Gallery2 that fails whenever I try to upload a photo.

  Re: ZendCore+FastCGI+IIS7 : Cannot embed PHP errors in response HTML. Always get 500 - Internal server error Reply Contact The problem seemed mostly to be comming from file permissions problems ... (Note the "access denied" error at the end of the IIS FastCgi Log) I resolved it by : Disabling file error logging in php.ini (because php tries to write an error log file, without having the right permissions - so it gives a 500 error each time php tries to write an error on file). Localhost browsing will now shows php errors in page. Setting detailed error in IIS7 (so external clients do not get 500 error) Guillaume
