preg_replace value dynamically php

Question

I want to change these links dynamically

from

mysite.com/some-link-here-t123.html
mysite.com/some-link-here-t456.html
mysite.com/some-link-here-t789.html

to

mysite.com/some-link-here-tid123.html
mysite.com/some-link-here-tid456.html
mysite.com/some-link-here-tid789.html

I tried using below

<?php 
$string2 = preg_replace('/-t([^0-9.html]*)/','-tid$1',$string);
?>

but its messing up all the other words starts from -t like -table becomes -tidable how to fix this?

Why do you have .html inside the character group? And why do you negate the group with ^ at the beginning? — Barmar

You need to limit your regex to only match numbers after the '-t' Like so:

<?php 
$string2 = preg_replace('/-t([0-9]+)/','-tid$1',$string);
?>

/-t([0-9]+)\.html/ just in case they have a URL like mysite.com/some-link-here-t90-t123.html
