Resetting the keys of an array after unset?

[duckduckgoose]

I'm trying to delete an element of an array and then reset the keys.

If I do this:

$colors = array('red','blue','green','yellow','purple','gold','silver');
$colors_key = 0;  //It won't always be 0, it could be 3 or 4, etc.

foreach($colors as $key => $value) {
      unset($colors [$colors_key]);
    }

$new_array = array_values($colors);

And then print out the array, I'll get this:

Array ([1] => blue [2] => green [3] =>yellow [4] =>purple [5] => gold [6]=>silver);

What I would like to get is this:

Array ([0] => blue [1] => green [2] =>yellow [3] =>purple [4] => gold [5]=>silver);

Anyone know how I can do this?

Hi,

You could have a look at the array functions, but I do not think there is a function for this, as most people like the keys to be specific for certain elements.

But..

I have no idea why you do this:

foreach($colors as $key => $value) {
      unset($colors [$colors_key]);
    }

$new_array = array_values($colors);

I might be missing something, but why not just do

      unset($colors [$colors_key]);

In regards to your gquestion, you could do something like..

unset($colors[$colors_key]);

$tmp = array();
foreach($colors as $key => value)
  {
  $tmp[] = $value;
  }
$colors = $tmp;
unset($tmp);

You can numerically reindex a single array with arrary_merge() or array_values().
