I need help extracting some info using a regex in PHP.

I have a string is like this

[email protected]

-> foo can change but is always lowercase alpha, variable length
-> tmp is ALWAYS tmp
-> uniqid is always lowercase alpha plus 0 to 9, output from uniqid() function
-> moontoast.com is ALWAYS moontoast.com

I need to extract the uniqid value from that string, using PHP.

Please help as my regex foo is weak

[email protected]

How about ^[a-z]+-tmp-([a-z0-9]+)@moontoast.com$? That should capture the uniqid in backreference 1.

In case you missed it on twitter: /.-([\w\d]+)@./

<?php
$email = '[email protected]';
preg_match('/[a-z]+\-tmp\-([a-z0-9]+)@moontoast\.com/', $email, $matches);
$uid = $matches[1];

/((\w+)-tmp-([a-z0-9]+))@moontoast.com/

<?php

preg_match_all('/(\S+)@moontoast\.com/', $string, $match);
foreach($match as $entry) {
  list($p0, $tmp, $p1) = explode("-", $entry[1]);
  // ...
}

Will grab anything after the last - and before the @:
/-([^-]*)\@/

@stuartherbert @maxmanders @robertbasic @JCook21 All of yours have various issues: must escape the 'dot' in "moontoast.com" or it would match anything like "moontoastecom" (the dot represents any character), one doesn't take the 'tmp' into account, and a few accept anything in the uniqid portion.

EDIT: Same general things apply to all the ones here.

@dhorrigan Good point. Updated to escape the '.'.

gah! github ate my stars in the regex :(

A humble vote for the solution proposed by @shama. Seems like foo, tmp, and anything after the @ are irrelevant.

@robertbasic use backticks ;)
