Hello,

This is kinda a noob question, but that's what i am :)

I have a 2 dimensions array (the first dimension are "normal" keys ) and in
the second dimension haves custom arrays but they all have a comon key that
is *id.
*The array comes ascending ordered by the numbers of *id* .

When i receive this array i need to look for and array that haves the
*id*== 0, so i do a for loop looking for it and i unset this values
after
that.
But need i need that the unset array looks like this sub-array never existed
( eg. if the key that with id = 0 was "5", the "5" will the number "6" and
"6" the "7" and so on).
Here is the code:

<?php

// $data the name of the array

//Look for the main email
for ($i = 0; $i < count($data); $i++) {
if ($data[$i]['id'] === 0) {
// It can't be empty
if (!empty($data[$i])) {
$this->email = $data[$i]['contact'];
$main_email_found = true;
}
unset($data[$i]);
}
}
?>

I have tree ways of doing this:

- Use a method that i that looks from duplicate entru based on the *id *key
as index and after and return the array ordered by this index.
- Adding a new entry to another array in this loop that not haves the
*id*== 0. and after that reverse the order
- Use the array_splice native function.

What do you recommend me ?
Sorry by the bad English.

Once you've cleared out the array of the data you don't want, would
the following output the right result?


sort($data);
foreach($data as $id => $node) {
$node['id'] = $id;
}
print_r($data);
