A proper way to test it might be including a HUGE (like Donald Trump Huge) a
file and see if there's a performance peak... like this:
<?php
$started = time();
if(FALSE){
require('my_huge_1Gb_bogus_file.php');
}
echo 'elapsed = '.(time()-$started);
?>
I'm thinking if elapsed time jumps thru the roof, then the file was accessed
and read into memory, but not executed thou. my_huge_1Gb_bogus_file.php
could just be <?php /* LOL OMG THIS IS A TEST LOL OMG THIS IS A TEST LOL OMG
THIS IS A TEST .... */ ?> repeated a zillion times so that the file size
would actually become gigantic.
Another thing is that if you use require and a non-existing file, php
doesn't throw an error if the require statement is unreachable, like behind
if(FALSE), only when the file really is included in the code.
