Where are you stuck? Post your code.

Hmm, let's hope I understand you correctly.  My code might be a little lazy, but it works for my simple example and might start you off on the right foot.  First it matches all <b>.*</b> strings in $text1.  Then replace any of those exact <b>.*</b> string found in text2 with an empty string.

 

$text1 = "Hello <b>test 1</b> this is a <b>test 2</b> and <b>test 3</b>!";
$text2 = "Hello <b>test 1</b> this is a <b>test 4</b> and <b>test 2</b>!";
preg_match_all(":<b>.*</b>:msU",$text1,$m);
print str_replace($m[0],"",$text2);

 

Output: "Hello  this is a <b>test 4</b> and !"
