strip_tags
Strip HTML and PHP tags from a string
(PHP 4, PHP 5)
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.
Parameters
- str
The input string.
- allowable_tags
You can use the optional second parameter to specify tags which should not be stripped.
Note:HTML comments are also stripped. This is hardcoded and can not be changed with allowable_tags.
ChangeLog
| Version | Description |
|---|---|
| 5.0.0 | strip_tags() is now binary safe |
| 4.3.0 | HTML comments are now always stripped |
| 4.0.0 | The allowable_tags parameter was added |
Examples
Example 2452. strip_tags() example
<?php
$text = '<p>Test paragraph.</p><!-- Comment --> <a href="#fragment">Other text</a>';
echo strip_tags($text);
echo "\n";
// Allow <p> and <a>
echo strip_tags($text, '<p><a>');
?>The above example will output:
Test paragraph. Other text
<p>Test paragraph.</p> <a href="#fragment">Other text</a>
Notes
Because strip_tags() does not actually validate the HTML, partial, or broken tags can result in the removal of more text/data than expected.
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.
