how to loop though an array and unset variables in the array

Question

is there a way to loop through an array and unset any variables that are =""? i am looking for a faster way to do this aside form writing 4 if else statements.i thought this might work but i don't know if it can be done this way or not.

$a=""
$b="123"
$c=""
$d"123"

$var=array($a,$b,$c,$d)

i am trying to loop through $var array to get

$var= array($b,$d)

is this even possible or should i stick with writing 4 if else statements?

`foreach($var as $k=>$v) if(!isset($v[0])) unset($var[$k]); ` or `$var = array_filter($var)` like @MarkBaker said. — Silviu-Marian, Sep 08 '14 at 22:21

$x=["","123","","345"];
$var = array_filter($x);
print_r($var);

The result:

Array
(
    [1] => 123
    [3] => 345
)

Have a look here : How to delete object from array inside foreach loop? or here : How do you remove an array element in a foreach loop?

foreach ($array as $key => $value) {
  if($value == "") {
    unset($array[$key]);
  } 
}

Good luck
