<?php // Declared unconditionally, so the implementation is bound to the name 'foo' as soon as the file loads. function foo() { echo "foo\n"; } if (true) { // Declared conditionally, so the definition is put into memory, but only "assigned" to the name "bar" here. function bar() { echo "bar\n"; } }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
