Array question: Deletion..

[Anon]

Hi guys:

I have a two dimensional array called $array, and I want to delete the fourth element in every second dimension. For instance, I want to delete all these records:

$array[0][4];
$array[1][4];
$array[2][4];
$array[3][4];

In other words, I'd like to delete every element where the second dimension = 4. And also, is it possible to have the 5th element in the array become the NEW 4th element.......after the deletion I mean...

Basically, I want to be able to delete certain columns and have all remaining columns move forward by one index.

All help will be appreciated...
Thanks..

Of course its possible:

<?php

function deleteCol($array,$col) {
for($i=0;$i < sizeof($array);$i++) {

$array[$i][$col] = $array[$i][$col+1];
$array[$i][$col+1] = "";

}// end for

return $array;

}// end function

So you would say something like:

 $newArray = deleteCol($array,4);

Now this has a lot of limitations, being there must exist a $col and $col+1 index. (ie. there must exist a 4 index and a 5 index). I hope this helps get you started though.

<?
foreach ($array as $key => $value) {
unset ($value[4]);
$array[$key][$value] = array_values ($value);
}
?>

the unset() function will delete the 4th element and the array_values() function reorders the elements.
