Question

I have out put like below

[0]
{
    [0]=>'a'
    [2]=>'b'
    [5]=>'c'
    [6]=>'d'
}

No What i want is to insert un-created array index and set their values to ‘0’.

e.g: in this case i want output like below instead of the one above. can any one show me a sample of code please…………. i tried to use array_fill() but didn’t work it just inserts array index at end.

array_fill($b1, 1, "0");

Desired Output:

[0]
    {
        [0]=>'a'
        [1]=>'0'
        [2]=>'b'
        [3]=>'0'
        [4]=>'0'
        [5]=>'c'
        [6]=>'d'
    }

Cycle through your array, watching the keys. Anytime the last iteration is more than 1 from the current key, perform a short while loop to catch up the array contents.

$newArray = array();
$lastKey = 0;

foreach ( $array as $key => $value ) {
  while ( $lastKey++ < $key ) $newArray[] = 0;
  $newArray[$key] = $value;
}

The output is:

Array
(
    [0] => a
    [1] => 0
    [2] => b
    [3] => 0
    [4] => 0
    [5] => c
    [6] => d
)
