[Resolved] I can't figure this error out!

[tgmsocal]

Ok, I can't figure out why I keep getting this error:

Fatal error: Cannot redeclare search_rank() (previously declared in /h1/adamspro/videodat/vdatsearch.php:148) in /h1/adamspro/videodat/vdatsearch.php on line 148

From this code:

uasort($rows, 'search_rank');

// ranking function for use in uasort
function search_rank($a, $b) {
	$ax = $a[score];
	$bx = $b[score];

if($ax == $bx) {
	return 0;
}

return ($ax > $bx) ? -1 : 1;
}

I know for a fact that search_rank is not defined anywhere else, and I have tried changing the name, and removing the "uasort" line. As long as the function code is present, the script gives me that error..

I have other functions in the same script that work just fine.. PLEASE HELP!

Thanks,

Hi,

If this is what your code looks like, you might have the call to uasort in the wrong place:

// ranking function for use in uasort
function search_rank($a, $b) {
    $ax = $a[score];
    $bx = $b[score];

if($ax == $bx) {
    return 0;
}

return ($ax > $bx) ? -1 : 1;
}

uasort($rows, 'search_rank');

i.e. you can't call a function if php does not know about it at that point.

hmm... PHP4 normally can deal with functions declared after they are used, actually.

Could you state your version of PHP, webserver and operating system, and provide the shortest and simplest example of code that demonstrates this problem?

The code snippet that you gave did not give me an error on PHP 4.3.9 running on Apache 2.0.52 on Windows XP.

is vdatsearch.php an include file

if it is you may be including the file twice there for declaring the function twice

[tgmsocal]

I had the function inside of a "while" loop..

That was it.

Thanks for the quick responses!
