What's the easiest way to grab a 6-character id from a string?
The id will always be after www.twitpic.com/ and will always be 6 characters.
e.g., $string = 'The url is http://www.twitpic.com/f1462i. Enjoy.';
$id = 'f1462i';
Thanks.

Here you go. Complete working code without regex :
<?php
$string = 'The url is http://www.twitpic.com/f1462i. Enjoy.';
$id = substr($string, strpos($string, 'http://www.twitpic.com/')+23, 6);
echo $id; //output: f1462i
?>

$string = "http://www.twitpic.com/f1462i" ;
$id = substr($string,strpos($string, 'twitpic.com')+strlen('twitpic.com')+1,6) ;
echo $id ;

preg_match("@twitpic\.com/(\w{6})@", "The url is http://www.twitpic.com/f1462i. Enjoy.", $m);
$id = $m[1];

@greg0ire: Why are you downvoting the answer when it was the OP who tagged the question "regex"?

@Alan Moore: because I didn't read the tags... I would cancel this if I could but it seems to be too late. I retag the question, regexes have nothing to do with this.
