This function tries to return a string with all NULL bytes, HTML and PHP tags stripped from a given str
. It uses the same tag stripping state machine as the fgetss() function.
The input string.
You can use the optional second parameter to specify tags which should not be stripped.
Note:
HTML comments and PHP tags are also stripped. This is hardcoded and can not be changed with
allowable_tags
.
Note:
In PHP 5.3.4 and later, self-closing XHTML tags are ignored and only non-self-closing tags should be used in
str
. For example, to allow both <br> and <br/>, you should use:<?php strip_tags($input, '<br>'); ?>
Returns the stripped string.
strip_tags()
allowable_tags
strip_tags()
Tag names within the input HTML that are greater than 1023 bytes in length will be treated as though they are invalid, regardless of the allowable_tags
parameter.
In PHP 5.3.4 and later, self-closing XHTML tags are ignored and only non-self-closing tags should be used in str
. For example, to allow both <br> and <br/>, you should use:
<?php strip_tags($input, '<br>'); ?>
<?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>
