PHP remove replace 3 characters after matched character

Question

I have a string like this:

$str = "This product price is 23,39 and sale end after 29th June";

I need to replace two characters after "," with ".-", so the output like:

This product price is 23.- and sale end after 29th June

I tried with but it remove last 3 characters:

 echo substr($string, 0, strlen($string) - 3);

Please help me to solve this issue.

A regex would be easier than substr. With substr you'll need to find the first occurance and use that in place of the 0. e.g. strpos. — user3783243

It is not clear what you are doing in the code. The second line of code addresses a different string variable than the first. Also, you don't seem to search for ,. — Mr Lister

First I will try to select the string that needs to be replaced:

substr($str, strpos($str, ","), 3);
// Gives me ,39 - 3 characters from the ,.

And now I'll replace it with the .--

<?php
  $str = "This product price is 23,39 and sale end after 29th June";
  echo str_replace(substr($str, strpos($str, ","), 3), ".--", $str);
?>

This gives me an output:

This product price is 23.-- and sale end after 29th June

Is this what you need? This is simple and doesn't need a RegEx. Not sure if RegEx will be more efficient in this case. I would go about doing this way.
