**ts** in html content should be replaced by **s.**

for example:
`sanktsya` => `sanksya`

That's how it works fine.

But `a` or `img` `urls` are changing.

**how to not changing urls ?**

**My code**

```
$str='<p>sanktsya boshlandi.</p>
<p><img src="https://img.com/Sqstso.jpeg" /></p>';

$result = preg_replace("/([qwrtpsdfghklzxcvbnmQWRTPSDFGHKLZXCVBNM]+)[tT]s/", "\${1}s", $str);

```
