I'm not sure that I understand your question. If the PHP
script is running within Apache, it will run as the Apache
user. Normally the apache user is 'www-data' or somesuch,
though it's configured in /etc/apache/httpd.conf -- e.g.,

User www-data
Group www-data

When you run a PHP script under Apache, Apache invokes a
subprocess to run as that user and that group, and that
subprocess runs the PHP script.

Another alternative is for the scripts to run suid, which
means that they run as the user who owns them.
