Using regular expressions and php

I tried to figure out how to convert the line under the line to several lines, where it will add a comma after two consecutive letters. Anyhelp is rated.

$myLine = "1234:21:3AB3459435:2343RT23432523:CD";
$myLine= preg_replace('/((?<=\[a-zA-Z]\b))/', ',', $myLine);

will be

1234:21:3AB,
3459435:2343RT,
23432523:CD,

thanking JP

Here, I came up with something quickly.

$myLine = "1234:21:3AB3459435:2343RT23432523:CD";
$myLine= preg_replace('/([a-zA-Z]{2})/', "$1,\n", $myLine);

Outputs:

1234:21:3AB,
3459435:2343RT,
23432523:CD,

Or if you do not want a comma with a comma:

$myLine = "1234:21:3AB3459435:2343RT23432523:CD";
$myLine= preg_replace('/([a-zA-Z]{2}(?!$))/', "$1,\n", $myLine);

Outputs:

1234:21:3AB,
3459435:2343RT,
23432523:CD
