Unknown Modifier - preg_match_all

Question

<?php
$url="example.com";
$get=addslashes(file_get_contents($adres)); 
$filter = "#/<\b\>(.*?)<\/b>/#i";
preg_match_all($get, $filter, $result); 
echo $result[0][0];
?>

While trying to work with these codes i get such an error like: "Unknown modifier '<'"

I read other answers about this problem. i know that the problem is about delimiters but what is the solution? Thanks for your helps from now on..

`preg_match_all (string $pattern, string $subject...)`; are you sure you got it right? — Salman A, May 10 '14 at 06:06
if not how should modify it? preg_match_all($get, $filter, $result); This is what i have now... — DanTeS9, May 10 '14 at 06:09
preg_match_all pattern must come first then the string preg_match_all(pattern, string, match) preg_match_all($filter,$get,$result); — Sirius_Black, May 10 '14 at 06:10
preg_match_all($filter,$get,$result); yes i got the sution with that order.. thanks ;) — DanTeS9, May 10 '14 at 06:17

You have incorrect order or arguments.Change :

 preg_match_all($get, $filter, $result);

To :

 preg_match_all($filter, $get, $result);

@user3412957 : `preg_match_all($filter, $get, $result); ` – arguments in the `preg_match_all` function in your code have incorrect order. – potashin May 10 '14 at 06:17

I'm pretty sure that the filter you are looking for is #<b>(.*?)</b>#i and not what you currently are using
