How to replace all matching regex of a sting in PHP

Question

sorry for not beeing able to put the title exactly what my question, I can't find a way to ask it.

So im trying to replace all ' in a text inside and replace it for ' in php

I have a variable $desc = "he's such a good person and he'll be very successfull";

and I'm trying to do the following

$desc = str_replace("&#39;","'",$desc);

But no success is there a way to use regex in str_replace?

Yes it looks to be fine now... for some reason.

Is there a way to use regex for it?

for example to remove html tags from the text?

$desc = "<strong> he's such a good person </strong> <br /> he'll be very successfull";

$desc = str_replace("<*>"," ",$desc);

You must have used `htmlentities` somewhere before the current line. Use `html_entity_decode` to decode the entities to their literal representations. — Wiktor Stribiżew, May 19 '17 at 08:57

You may try to use the correct PHP function to do this job, so please take a look at : preg_replace doc.

In your case, you would like to use like this :

preg_replace('/&#39;/', "'", $desc);

Take a look at this execution: https://eval.in/800948

Can this be used for an example `preg_replace('<*>', " ", $desc);`? – Juanfri Lira May 19 '17 at 08:59
of course @JuanfriLira you can use it like this : `preg_replace('/\<.*\>/', "", $desc);` to replace text between "<" and ">". – Sense May 19 '17 at 09:02

Does it have to be a regex because this is a lot simpler way to do it

$desc = "he&#39;s such a good person and he&#39;ll be very successfull";

$new = str_replace('&#39;', "'", $desc);
echo $new;

RESULT:

he's such a good person and he'll be very successfull

You don't need to use regex as it will be more complex use

$desc = "he&#39;s such a good person and he&#39;ll be very       successfull";
$desc = str_replace("&#39;","'",$desc);
echo "after replace :"." ".$desc;

it is more simpler :)
