[RESOLVED] array_pop problem

[mrbaseball34]

Got this array:

$a = array("", "DPKA-18PG-7", "", "NS", 10, "Connector", "", "", "", "", "");

If I do this:

  array_shift($fields_order); // remove the first element
  array_pop($fields_order); // remove the last 4 elements
  array_pop($fields_order); 
  array_pop($fields_order);
  array_pop($fields_order);

I should get this:

array("DPKA-18PG-7", "", "NS", 10, "Connector");

But, instead, I'm getting this:

Array ("DPKA-18PG-7", "", "NS", 10, "Connector", "");

But, if I add another array_pop, which should remove the last empty element,
I get this result:

Array ("DPKA-18PG-7", "", "NS", 10);

which has 5 trailing empty elements

No, you shouldn't. You really should get

array ("DPKA-18PG-7", "", "NS", 10, "Connector", "");

And it does remove the last empty element.

Apart from that, 6 function calls is unnecessary when one would suffice.

$a = array("", "DPKA-18PG-7", "", "NS", 10, "Connector", "", "", "", "", "");
$slice = array_slice($a, 1, 5);

What's the big mystery?

$a = array(1, 2, 3, 4, 5, 6);

// $a is...
array_shift($a); // 2, 3, 4, 5, 6
array_pop($a); // 2, 3, 4, 5
array_pop($a); // 2, 3, 4
array_pop($a); // 2, 3
array_pop($a); // 2
