How do you reindex an array in PHP?

I have an array:

$input =array{0 => 'a', 1 => 'b',2 => 'c'}

Then, If I destroyed a variable in the array. Like this:

unset($input[1]);

The array will be like this:

$input =array{ 
    0 => 'a',
    2 => 'c' 
}

I want to rearrange it to become like this:

$input =array{ 
    0 => 'a',
    1 => 'c' 
}

How can I do it?

Thanks

A quick look into the online manual suggests to use array_values();

$input = array_values($input);

Check the online manual for further information

$input = array_values($input);

There are lots of sorting methods in php. Have a look: http://php.net/manual/de/array.sorting.php

As i think you want to sorty by key, ksort() should to it.

EDIT: Just have seen that ksort() is not what you are looking for. Use array_values()
