PHP striptags allowing only title attribute.

[Mudsaf]

Hello, i'm wondering how to striptags span element only allowing title attribute on it.

I'm not sure what you're asking, do you have an example? strip_tags doesn't do anything with attributes, only entire tags.

Well if user enters tags example

$MyString = '<span style="display:block;" title="WADAP">MyText</span>';strip_tags ($MyString,"<span title>"); //So this would remove the style attribute.

Result should look like

<span title="WADAP">MyText</span>

strip_tags doesn't remove attributes, it removes tags. You'll need to use a regular expression if you want to remove attributes.

I found tutorial for style, but didin't find method to remove ID and CLASS attributes.

preg_replace('/style=(["'])[^1]*?1/i', '', $item, -1);

I see several examples if I do a search. If this is user-generated HTML then it would be safer to load the HTML into a DOMDocument object and traverse through the nodes, where you can call removeAttribute to remove attributes for a node and then write out the final HTML. DOMDocument will behave better for broken HTML.
