Preg_replace all but digits and . and ,

Question

I'm trying to preg_replace all but Digits and . and , symbols. From a string,

can be

nksdfojsdfjdsfojdsjofsojdfjo213-9sdfknmcfsjozx -xdcv-cv,1239103

Output using preg_replace or any other solution would return just the numbers and allow for comma and dot signs.

To end up with a1,322.44 as 1,322.44

This is what I tried

$carPrice=preg_replace('/\D/', '', $carPrice);

Would write three more paragraphs if it is necessary, don't seem to find the answer.

Use [^0-9\.,] as your matching expression.

You updated the question just fine. Asking questions takes a bit of practice, just like everything else. I prefer to answer rather than comment in such situations. – Feb 12 '13 at 23:28
Escaping dots inside of a character class is not necessary. Explaining every answer that you post is necessary. – mickmackusa Sep 25 '20 at 03:29

you can use this:

preg_replace('#[^0-9\.,]#', '', 'your value');
