Question

I am using IIS as a webserver on my development machine for PHP webdevelopment. Or at least, I am trying to.

When there is a syntax error in a PHP script and I open that file in my webbrowser, I just get an 503 "internal server error" and the default IIS error page for this error. Some browsers dont open that file at all, possibly because of the 503 HTTP Response Header.

I would like IIS to act in that case just like the apache webserver: display the PHP file with the error anyway, so that the error message gets printed out.

How can this be done?

EDIT:

PHP settings:

display_errors

is on and

error_reporting

is set to E_ALL

Answer 1

With IIS7, it doesn't pass the errors through by default. It's "existingResponse" that needs to be set.

You can set it by running the following (make sure to replace {sitename} with your site name).

c:\windows\system32\inetsrv\appcmd.exe set config "{sitename}" -section:system.webServer/httpErrors /existingResponse:"PassThrough" /commit:apphost

Answer 2

In your php.ini set:

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT
display_errors = On

And if you want them logged:

log_errors = On

Answer 3

To enable detailed errors for PHP (and other languages), run this command from the command line:

%windir%\system32\inetsrv\appcmd.exe set config -Section:system.webServer/httpErrors -errorMode:Detailed

Then

IISReset

Answer 4

A best practice would be to log "silently" in a file.

But you can have both by setting the following value in your php.ini file to a logfile

error_log=<File Location>
