array_splice function problem

hi,
i have i problem with array_splice function.
i have following code:

<? $input = array (11=>"a", 22=>"b", 33=>"c", 44=>"d");
      array_splice ($input, 1, 1);
      foreach($input as $ind=>$val) {
            echo "$ind=>".$val."<br>";
      };
?>

and it gives following result:
0=>a
1=>c
2=>d

instead of
11=>a
33=>c
44=>d

what i was expecting.
am i doing something wrong? how to delete some array member and keep these indexes?

thanks in advance

in this case you could just use:
unset($input[22]);

but array_splice does not preserve keys, and you would have to write your own associative array splice function, or use one from the array_splice php manual (php.net/array_splice) comments.

what about this:
<? $input = array (11=>"a", 22=>"b", 33=>"c", 44=>"d");
     foreach($input as $ind=>$val) {
          echo "$ind=>".$val."<br>";
     };
?>

Hello kirez,

<?php

function new_array_splice($input, $position, $count) {
      $i = 0;
      foreach($input as $key => $value) {
             if($i < $position or $i > $position + $count - 1) {
                     // echo $key ." => ".$value;
                     $output[$key] = $value;
             }
      $i++;       
      }
      return $output;
}

$input = array (11=>"a", 22=>"b", 33=>"c", 44=>"d");

$output = new_array_splice($input, 1, 1);

print_r($output);

?>

Just noticed that you accepted  Roönaän 's solution. I wrote a function to do what you wanted so here.
