finding key instead of value

[foxfirediego]

Ok I have the following array:

PHP Code:

$names = array("Venore", "Folda", "Dame"); 


And I can print like this:

PHP Code:

$names[0]; -> return Venore
$names[1]; -> return Folda
$names[2]; -> return Dame 


but, what if I want to use:

PHP Code:

$names[Venore]; -> return 0
$names[Folda]; -> return 1
$names[Dame]; -> return 2 


thanks
