Reindex a numberic array

[Cep]

Hello,

 

Is there a function which will re-index a numeric array?

 

For example if I do this,

 

<?php

$myarray = array(red, yellow, green, blue);

unset($myarray[1]);
unset($myarray[3]);

print_r(array_keys($myarray));

// will show
// Array ( [0] => 0 [1] => 2 )
?>

 

As you can see the second key has an index of 2, I would like to re-index this to 1 as that is the next index number available. I have been looking through the php docs and so far have not found a function that does this, does anyone know if this functionality even exists?

Its ok just found it! array_values() will re-index the numerical array
