Re: [PHP-DEV] PHP 4.0 Bug #6956 Updated: empty( "0" ) returns true From: Matthew Hagerty (mhagerty <email protected>)
Date: 09/29/00

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);
}

Enjoy,
Matthew
