vs.
<?php

<html><head><title>{$title}</title></head><body><?php if(true) { ?>TRUE!<?php } else { ?>FALSE!<?php } ?></body></html>
';
$array = array (

?>
Conclusion
NOTE: Despite low-load results
which point to the same loading time (because of the margin of error),
the high-load results are pretty conclusive.After an average of 10000 cycles, the fastest option is Benchmark 2!
