As I told most important part that number changes everytime so when a preg match it it doesn't recognize
how can i solve a problem like this ?

 

preg_match('~<div id="post_message_\d+">(.*?)</div>~s', $text, $match);

echo $match[1];

PHP:

This should do it.

 

$str = '<div id="post_message_2052965">Hello Everyone<br /><br />There is a good movie for you all, a good creation from Mrinal Sen. <br />Cast:Utpal Dutt, Suhasini Muley, Shekar Chatterjee and others...<br />Story by Banafool<br />VCD quality, Size: 930MB<br /><br />Hope you will like and if so please leave your comments...</div>';
echo strip_tags($str, '<br>');

PHP:
