Question

I have some text for ex: This is <b>an</b> example <b>text</b>.

How would I remove all the text that is within bold tags, so it should output this:

This is example.

Answer 1

Use preg_replace()
If you would like to remove a simple tag along with the text inside it:

<?php 
$string = 'This is <b>an</b> example <b>text</b>';
echo preg_replace('/(<b>.+?)+(<\/b>)/i', '', $string); 

Output:
This is example

And whit a regular expression (class, id), spacing errors and antislashe:

<?php
$string = 'This is <b class="c1" id=\'c2\'>an</b> example <b>text</B >'; 
echo preg_replace('@<(\w+)\b.*?>.*?</\1.*?>@si', '', $string); 

Output:
This is example
