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.
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. This is hardcoded and can not be changed with allowable_tags .
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
