[SOLVED] if statement evaluation order

[rtpmatt]

I am just wondering what the evaluation order of an if statement in PHP is, and if it stops evaluating if it passes or fails?

 

thanks

Left to right.

Yes.

 

 

<?php
$a = 1;
$b = 2;

if ($a || $b/0) echo 'true';             // true (as $a evaluates to true).

$a = 0;

if ($a || $b/0) echo 'true';             // div by zero error as second bit needs to be evaluated

?>
