Subject: Re: [PHP-DEV] [PATCH] New functions: array_key_index(), array_first(),
 array_last()
From: info@adaniels.nl (Arnold Daniels)

+1
Currently there is no way to get a key from an array without either 
moving the cursor or first getting all keys and go from there. While 
these function are easily written in PHP, the implementation feels more 
like a dirty workaround than a solid solution. I would personally use 
these functions and I think many others will as well, so they are worth 
being included.
