preg_replace [ca3.php.net] seems like a good bet for what you are looking for.

$string = "ABC123";
$number = preg_replace('/[^0-9_]/i','',$string);
$code = preg_replace('/[^a-z_]/i','',$string);

something like that?

preg_match_all [us.php.net] seems to be a little more appropriate for this situation if you want to "use" the codes. This should match all of them:

$matches = array();
$pattern = "/([A-Z]+)([0-9]+)/";
preg_match_all($pattern,$string,$matches);
echo '<pre>';
print_r($matches);
echo '<pre>';

Good luck! :)

You can use the e modifier to evaluate the backtracked variables to populate the $code and $number variables with the appropriate data:

$dmb=preg_replace(/^([a-z]+)([0-9]+)$/ie',"\$code=\"\\1\";\$number=\\2;",$string);

Should be:

$dmb=preg_replace('/^([a-z]+)([0-9]+)$/ie',"\$code=\"\\1\";\$number=\\2;",$string);

I used the following solution:

$number = preg_replace('/[^0-9_]/i','',$name);
$code = preg_replace('/[^a-z_]/i','',$name);

However it replaces all numbers in the string, but i have realised that some of the codes contains numbers i.e.

IDHG2HG10
code = IDHG2HG
number = 10

ID2H3
code = ID2H
number = 3

I need to be able to get the number after the code only which may contain numbers :D confusing i know

[BananaFish]

If the number is simply the ending digits, try this:

preg_match('/^(\w+)(\d+)$/',$name,$matches);
if($matches[0]){
 $code=$matches[1];
 $number=$matches[2];
}
else {
 $code="Not Found";
 $number="Not Found";
}

WORKED A TREAT!
