Re: PHP 4.0 Bug #6956 Updated: empty( "0" ) returns true

The function empty() is really confusing and once I read the docs on it I realized I was using it for the wrong purpose. I wrote a quick function that does what I thought empty() was doing. Hope this helps. /* * Determine is a string is *really* empty. */ function blank($sString) {

        /*
         * Make sure we really got passed a string.
         */
        settype($sString, "string");

        $sTemp = trim($sString);

        if ( strlen($sTemp) <= 0 )
                return(true);

        return(false);
