I would use "sudo" for this. It allows non-root users to execute only the
scripts you specify as root. Take a look at "man sudo" and "man visudo".
For example, if you wanted your PHP scripts to be able to run the script
"/usr/bin/foo" as root, you'd put an entry like the following in your
/etc/sudoers file:
www-data ALL=NOPASSWD: /usr/bin/foo
If you can change the permissions/ownership on the file(s) in question it
might be better to create a new group to own the files and make them group
writable, then put the "www-data" user into the new group.
