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

<p><code>file_get_contents('http://example.com/foo.php');</code> and NOT e.g. <code>$holding_var = file_get_contents('http://example.com/foo.php');</code></p>

<p>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?</p>
