[RESOLVED] Help splitting an array into a string based on alpha or numeric

[shawjames]

I need help breaking a string up into an array of string parts, based on alpha or numeric values. Basically, I need to break up these strings:

abc123xyz456

into an array of values, broken up by the alpha parts and numeric parts, like this:

array("abc","123","xyz","456");

In my application, it is safe to assume the string always starts with alpha characters.

Any ideas on the best way to accomplish this?

Would all they be always 3 letter in length?

A quick dirty way

<?
$string = "abc123xyz45685" ;

$numbers = preg_replace("/[a-z]/", '-', $string);
$texts = preg_replace("/[0-9]/", '-', $string);

$numbers= clean_and_make_array($numbers);
$texts= clean_and_make_array($texts);
print_r($numbers);
print_r($texts);

function filter($var){
	return strlen($var) > 0;
}

function clean_and_make_array($string){

$string = explode("-", $string);
$string = array_filter($string, "filter");
$string = array_values($string);
return $string;
}

$string = 'abc123xyz456';
$t = preg_split('/(?<=\d)(?=\D)|(?<=\D)(?=\d)/', $string);
print_r($t);
