highest "element" in an array

[SchweppesAle]

hi, I wanted to know if there's a method which returns the highest element number in an array rather than the highest value ex: max()

 

Thanks

something which collapses all "NULL" elements within an array would work too.  EX:

 

array1:

[0]  = 10
[1] = NULL
[2] = NULL
[3] = NULL
[4] = 5
[5] = 8

somemethod(array1)

newarray:
[0] = 10
[1] = 5
[2] = 8

as for your 2nd question:

 

$temp = array();
foreach($array as $element){
  if($element !== NULL){
    $temp[] = $element;
  }
}
$array = $temp;

 

//edit:

 

to get the highest index, why not use count($array)-1; //(provided the index is continuous) else:

use array_keys() with end()
