If it's Apache + mod_php, execute permissions are not required. (If  
it's Apache + CGI PHP, they are.)

The command line can go both ways too:

This requires execute permission and the file must begin with an  
appropriate hash-bang such as #!/usr/bin/php :
$ ./myphpfile.php

This does not require execute permission:
$ /usr/bin/php myphpfile.php
