strip_tags -- Strip HTML and PHP tags from a string

Description

string strip_tags ( string str [, string allowable_tags] )

This function tries to return a string with all HTML and PHP tags stripped from a given str . It uses the same tag stripping state machine as the fgetss() function.

You can use the optional second parameter to specify tags which should not be stripped.

Warning

Because strip_tags() does not actually validate the HTML, partial, or broken tags can result in the removal of more text/data than expected.

Warning

This function does not modify any attributes on the tags that you allow using allowable_tags , including the style and onmouseover attributes that a mischievous user may abuse when posting text that will be shown to other users.

Example 1. strip_tags() example

<?php
$text = '<p>Test paragraph.</p><!-- Comment --> Other text';
echo strip_tags($text);
echo "\n";

// Allow <p>
echo strip_tags($text, '<p>');
?>

The above example will output:

Test paragraph. Other text
<p>Test paragraph.</p> Other text

strip_tags() has been binary safe since PHP 5.0.0
