? : operator

[drawmack]

I cannot find documentation in the manual on the ? : the only reference I can find to it is a mention on the operator precedence page.

Could someone point me to a reference on this please?

the docu page is http://de3.php.net/manual/en/language.expressions.php , somewhere in the text:

There is one more expression that may seem odd if you haven't seen it in other languages, the ternary conditional operator:

<?php
$first ? $second : $third
?>

If the value of the first subexpression is TRUE (non-zero), then the second subexpression is evaluated, and that is the result of the conditional expression. Otherwise, the third subexpression is evaluated, and that is the value.

I.e., if u want a string to be "yes" or "no" depending on the value of some boolean var, u could do it -very straightforward- like this:

$isTrue = $boolVar ? "yes" : "no";
