file_get_contents memory issue
I'm using file_get_contents just to call a php file (which returns some data); like that:

`file_get_contents('foo.php');` and NOT e.g. `$holding_var = file_get_contents('foo.php');`

Will it use the assigned memory of 20kB (let's say the meant file called by my script returns a 10kB response) or will not use the memory at all since the result is not stored in any variable?
