strip_tags -- Strip HTML and PHP tags from a string
[B]Description[/B]
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 [URL="mk:@MSITStore:K:\Web\PHP\Articles\php_manual_en.chm::/en/function.fgetss.html"]fgetss()[/URL] function.
You can use the optional second parameter to specify tags which should not be stripped. [INDENT]????: 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.
[/INDENT]
?????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.
