Hi all I have this in a simple routine... for($i=0, $if=count($array); $i<$if; ++$i)

      if( $array[$i] == '' )
      {
              array_splice( $array, $i, 1);

              --$i;

My question: is this the better way to do it? -- Martin Scotta

array_filter() will return an array without any elements that equate to false (empty strings, 0, false) although you can use the optional argument to specify your own function which should return true if you want to keep an element, or false if you want to ditch it, if you need to eliminate only empty strings.

I'd just do foreach($array as &$v) {

    if($v === false || $v === null || $v === 0) {
        unset($v);
    }

} I wouldn't do anything more complicated >.>

And you would unfortunately find it doesn't work. Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP
