Doc said : "Returns TRUE if val is 'not a number', else FALSE."
That's not true
exemple :
<?php
$foo= 1;
$bar = '2';
$more = 'shqsdfklhsdfo';
$moreFoo = true;
$moreBar = false;
var_dump(is_nan($foo)); //return bool(false)
var_dump(is_nan($bar)); // return bool(false)
var_dump(is_nan($more)); //return NULL (not TRUE)
var_dump(is_nan($moreFoo )); //return bool(false)
var_dump(is_nan($moreBar )); // return bool(false)
?>
