    copied!<p>I am trying to write a preg_replace that will clean all tag properties of the allowed tags, and all tags that do not exist in the allowed list.</p> <p>Basic example- this: </p> <pre><code>&lt;p style="some styling here"&gt;Test&lt;div class="button"&gt;Button Text&lt;/div&gt;&lt;/p&gt; </code></pre> <p>would turn out to be:</p> <pre><code>&lt;p&gt;test&lt;/p&gt; </code></pre> <p>I have this working well.. Except for img tags and a href tags. I need to not clean the properties of the img and a tags. Possibly others. I was not sure if there was a way to set two allow lists? </p> <p>1) One list for what tags are allowed to stay after being cleaned<br> 2) One list for the tags that are allowed but left alone?<br> 3) The rest are deleted.</p> <p>Here is the script I am working on:</p> <pre><code>$string = '&lt;p style="width: 250px;"&gt;This is some text&lt;div class="button"&gt;This is the button&lt;/div&gt;&lt;br&gt;&lt;img src="waves.jpg" width="150" height="200" /&gt;&lt;/p&gt;&lt;p&gt;&lt;b&gt;Title&lt;/b&gt;&lt;br&gt;Here is some more text and &lt;a href="#" target="_blank"&gt;this is a link&lt;/a&gt;&lt;/p&gt;'; $output = strip_tags($string, '&lt;p&gt;&lt;b&gt;&lt;br&gt;&lt;img&gt;&lt;a&gt;'); $output = preg_replace("/&lt;([a-z][a-z0-9]*)[^&gt;]*?(\/?)&gt;/i", '&lt;$1$2$3$4$5&gt;', $output); echo $output; </code></pre> <p>This script should clean the $string to be:</p> <pre><code>&lt;p&gt;This is some text&lt;br&gt;&lt;img src="waves.jpg" width="150" height="200" /&gt;&lt;/p&gt;&lt;p&gt;&lt;b&gt;Title&lt;/b&gt;&lt;br&gt;Here is some more text and &lt;a href="#" target="_blank"&gt;this is a link&lt;/a&gt;&lt;/p&gt; </code></pre>
