arrays

[Ted_Haller]

Hi,

This is probably a very stupid question...

How does one find out what the index is of a particular array element?

I have an array of image names, and given a particular image name, I'd like to know where it is in the array.

e.g.

$img_array = ('img1', 'img2', 'img3', ...);

echo $img_array[2]; would give me 'img3'. but how do I find out that 'img3' is the 3rd element?

Thanks

Ted

<?
$lookingFor = "img3";

$array[]="img1";
$array[]="img2";
$array[]="img3";
$key = array_search($lookingFor,$array);
if ($key != "") {
	print "$lookingFor is element #$key in array";
} else {
	print "$lookingFor DOESN'T exist in array";
}
?>
