How can I implode an array while skipping empty array items?

Question

Perl\'s join() ignores (skips) empty array values; PHP\'s implode() does not appear to.

Suppose I have an array:

$array = a         


        

Answer 1

Try this:

$result = array();

foreach($array as $row) { 
   if ($row != '') {
   array_push($result, $row); 
   }
}

implode('-', $result);
