Question

I have this:

$text = 'text text text s html tagove
<div id="content">ss adsda sdsa </div>
oshte text s html tagove';
$content = preg_replace('/(<div\sid=\"content\">)[^<]+(<\/div>)/i', '', $text);
var_dump($content); 

But if the <div id="content"></div> contains other tags, such as <b>,<i> etc, it does not work.

For example:

$text = 'text text text s html tagove
<div id="content"><b> stfu </b> ss adsda sdsa </div>
oshte text s html tagove';

Answer 1

You can use lazy quantifiers instead.

$s="foo<div>Some content is <b>bold</b>.</div>bar\n";

print preg_replace("/<div>.+?<\/div>/i", "", $s);'

output:

foobar

UPDATE per comments:

[ghoti@pc ~]$ cat doit.php 
<?php

$text = 'text text text s html tagove
<div id="content"><b> stfu </b> ss adsda sdsa </div>
oshte text s html tagove';

print preg_replace('/<div id="content">.+?<\/div>/im', '', $text) .  "\n";

[ghoti@pc ~]$ php doit.php 
text text text s html tagove

oshte text s html tagove
[ghoti@pc ~]$
