Parsing this string with regex PHP [closed]

Question

I have string in format as below:

ABC 318 XY2388

I tried to use preg replace function in PHP with Regex but having no knowledge of reg ex I am not getting anywhere.

I want above string to end up like ABC 318/XY 2388

So the rule is:

I will appreciate any help on this.

What kind of letters/digits? Unicode? Only ASCII? Also, there already is a space between ABC and 318, but not between XY and 2388 - that doesn't match your description. — Tim Pietzcker, Jul 9 '13 at 14:57

This code changes the string using the corrected rule/example you are giving:

  $input = "ABC 318 XY2388";
  $output = preg_replace("/([A-Z]*) (\d*) ([A-Z]*)(\d*)/","$1 $2/$3 $4", $input);
  echo $output;

Result: ABC 318/XY 2388

Slightly changed the question. Sorry about this. – Sahil Jul 9 '13 at 14:54

Thanks a lot!, If the first batch of letters were unknown then what happens? – Sahil Jul 9 '13 at 15:02

I mean if the ABC was not know then how can I solve it?, in future it may be ABB, AVC or anything – Sahil Jul 9 '13 at 15:03

Modified the answer so the first batch is dynamic (in the previous answer, it was fixed to "ABC") :) – Racso Jul 9 '13 at 15:03

Thanks Much appreciated... – Sahil Jul 9 '13 at 15:04
