Note that } elseif() { is somewhat faster than } else if() {
===================================
Test (100,000,000 runs):
<?php
$start = microtime(true);
for($i = 0; $i < 100000000; $i++) {
if(2 === 0) {} else if(2 === 1) {} else {}
}
$end = microtime(true);
echo "1: ".($end - $start)."\n";
unset($start, $end);
$start = microtime(true);
for($i = 0; $i < 100000000; $i++) {
if(2 === 0) {} elseif(2 === 1) {} else {}
}
$end = microtime(true);
echo "2: ".($end - $start);
?>
===================================
Result (depending on hardware configuration):
1: 20.026723146439
2: 20.20437502861
