strip_tags
(PHP 3 >= 3.0.8, PHP 4, PHP 5)
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.
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.
Return Values
Returns the stripped string.
Examples
Example 1. 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
| 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.
