(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.
You can use the optional second parameter to specify tags which
should not be stripped.
Note:
allowable_tags was added in PHP 3.0.13
and PHP 4.0b3. Since PHP 4.3.0, HTML comments are also 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.
|
Example 1. strip_tags() example |
<?php
$text = '
<p>Test paragraph.</p>
<!-- Comment -->
Other text';
echo strip_tags($text);
echo "\n\n-------\n";
echo strip_tags($text, '<p>');
?>
|
The above example will output:
Test paragraph.
Other text
-------
<p>Test paragraph.</p>
Other text |
|
| 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.
