I’m looking for a PHP function to close HTML tags.

I’m building a site that has admins entering content in a “WYSIWYG” editor. Some of the screens will only show part of the content and then prompt the user to “click for more”. So I need to be able to close all the HTML tags that were opened in the part of the content that is initially displayed.

Thanks for any help

    I think you can do this by running the HTML through something like tidy. An extension for this is available in PHP.

    For example, suppose you had a fragment like this

    <h1>hello

<table>
<tr><td>and you cut the text right here... </t

    Thorny! Dangling tags and a truncation in mid-tag!

    Here’s what you’d get back

    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<meta name="generator" content=
"HTML Tidy for Linux/x86 (vers 25 March 2009), see www.w3.org">
<title></title>
</head>
<body>
<h1>hello</h1>
<table>
<tr>
<td>and you cut the text right here...</td>
</tr>
</table>
</body>
</html>

    Pretty impressive! Now all you need to do is just extract the repaired fragment back out of the body element.
