I think it is possible in php 5.3.4 – Dmitri Snytkine Oct 28 '11 at 13:37

@DmitriSnytkine: Nope. Not possible until php5.4. Here it is in [php5.3](http://codepad.viper-7.com/Q93M7O), and here in [5.4](http://codepad.viper-7.com/75VMlc)... – ircmaxell Oct 28 '11 at 13:41

This has been asked at least 4 million times on SO before. Seriously, does it hurt to search before you ask? – middus Oct 28 '11 at 13:50

@middus, this would be a tough one to search for. – John Cartwright Oct 28 '11 at 14:14

@middus Let us bow down to your search prowess. My point is, looking at the terms you've used it would not be obvious to the majority of the users what you are looking for. I would have not though to use those specific terms. – John Cartwright Oct 28 '11 at 15:04

There currently is no support for this in PHP. I believe PHP 5.4 (which is in BETA testing right now) is going to support this though.
for now you would just have to break it in two lines:
$arr = explode('-', 'a-b-c');
$arr[1]

or you can convert these 2 lines into a function and use it in one line... – Sgn. Oct 28 '11 at 13:45

This is currently not possible with the stable release of PHP (5.3), but will be included in PHP 5.4. The feature is already marked as "implemented" in the rfc list of the php wiki.
