Redirect missing PHP files to a single file

[ofcalcul]

I have to redirect any link to a page that doesn't exist on my website to the /index.ph file.
For the html, htm, jpg files it works fine with
ErrorDocument 404 /index.php
in the .htaccess file.
For the PHP files it doesn't work at all, I get an 404 error message too in Internet Explorer and a "No input file specified." in Mozilla Firefox.
Do you have any idea how could I solve this for the PHP files too?
The shorter idea is:
the link to

http://www.myweb.com/pagewichdoesntexist.php

I need to redirect it to

http://www.myweb.com/index.php

Thank you,
Cristian

ofcalcul,

I haven't had a problem redirecting error pages myself. The problem could be that the error code is something other than 404.

What do your Apache log files show?
