[RESOLVED] What does this statement do?

[chads2k2]

Hey, I was looking through some code from another source and saw this again. I have seen an if statement written like this before and just want some explanation to what it does.

Thanks guys,
Chad

Oh yeah the code:

<?php
$q = isset($_GET['q']) ? $_GET['q'] : '';
?>

[thorpe]

it is shorthand for...

if (isset($_GET['q'])) {
  $q = $_GET['q'];
} else {
  $q = '';
}

Thorpe beat me to it, cos it took me a moment to find it in the manual, and because he probably knew it off the top of his head :-)

It is called a "ternary conditional operator": http://us3.php.net/expressions (towards the middle of the page).

Thanks Rodney,

Yeah Thorpe beat you to it, but it was what I already knew. 🙂 So I would have given you the points if there were any to this one. Because you gave me the manual page to it.

Thanks to you both,
Chad
