Not if it's mod_php, instead of PHP as a cgi binary....

PHP runs as "httpd" on many servers. That means the PHP script only has the same access privileges as someone browsing your website. You can see why making a public file 0777 (writable + deletable by the outside public) would be bad.

Rather than try to edit the contents of the PHP from another PHP, have the PHP grab data from a database or external file outside your web directory.

Like:

/usr/elvis/includedata.txt
/usr/elvis/www/myphpscript.php

chmod /usr/elvis/includedata.txt 0777

in myphpscript.php, you can read from and write to includedata.txt without worrying about the public getting access to that file.
