key for in_array()

[tedd <tedd@xxxxxxxxxxxx>]

Hi gang:

Does anyone have a slick way to determine what the key would be for a 
successful find in in_array()?

Such as:

if (in_array($var, $array))
   {
   // what's they key for *this* successful find?
   }

I know I could use:

foreach($array as $key => $value)
   {
   if ($value == $var)
     {
      // then I know what the key would be.
     }
   }

But is there a simpler way using in_array()?

Cheers,

tedd
