PHP remove the first index of an array and re-index

Question

I have an array like Array

(
    [0] => A
    [2] => B
    [4] => C
    [6] => D
)

I want to remove the first element and then re-index array to get the output

(
    [0] => B
    [1] => C
    [2] => D
)

Which PHP function i need to use?

Update

Input array is

Array
(
    [0] => Array
        (
            [0] => Some Unwanted text
            [1] => You crazyy
        )

    [2] => Array
        (
            [0] => My belowed text
            [1] => You crazyy
        )

    [10] => Array
        (
            [0] => My loved quote
            [1] => You crazyy
        )

)

And the output should be like

Array
(
    [0] => Array
        (
            [0] => My belowed text
            [1] => You crazyy
        )

    [1] => Array
        (
            [0] => My loved quote
            [1] => You crazyy
        )

)

Please use [`var_export`](http://php.net/manual/en/function.var-export.php) so it's easier to test. — Matthew Flaschen, Jun 09 '10 at 06:12

You can use

array_shift($array)

i dont think array_shift would reindex the array – lemon Jun 09 '10 at 05:32
@lemon: the manual says otherwise: `All numerical array keys will be modified to start counting from zero` – intuited Jun 09 '10 at 05:53

Please see the updated question, array_shift trick is not working if the values of passing array is again an array – Mithun Sreedharan Jun 09 '10 at 05:54
Melmacian's answer with array_splice seems to be working, any one tried that? – Mithun Sreedharan Jun 09 '10 at 06:03
For me (PHP 5.3.2, Ubuntu), it gives the output requested in the updated question. – Matthew Flaschen Jun 09 '10 at 06:16

With array_splice.

http://www.php.net/manual/en/function.array-splice.php

php > print_r($input);
Array
(
    [0] => A
    [2] => B
    [4] => C
    [6] => D
)
php > array_splice($input, 0, 1);
php > print_r($input);
Array
(
    [0] => B
    [1] => C
    [2] => D
)

Need to omit the third parameter array_splice($input, 0) – Mithun Sreedharan Jun 09 '10 at 05:58

Use array_splice($input, 1); // 1 is start index to get this array ([0] => B, [1] =>C, [2] => D) – sayvortana May 01 '13 at 11:05
This is perfect if you want the actual array returned from the function, which is what I needed. Rather than using `array_shift` which returns the removed element for some reason known only to the PHP Devs?!? – superphonic Apr 04 '17 at 16:36

we can do it with array_shift() which will remove the 1st index of array and after that use array_values() which will re-index the array values as i did not get from the @User123's answer, try below one:

<?php
    $array = array(
                0 => "A",
                2 => "B",
                4 => "C",
                6 => "D"
            );
    array_shift($array);
    $array = array_values($array);
    echo "<pre>";
    print_r($array);

Output: check the output here https://eval.in/837709

Array
    (
        [0] => B
        [1] => C
        [2] => D
    )

Same for your Updated Input array

<?php
    $array = array(
                    0 => array(
                            0 => "Some Unwanted text",
                            1 => "You crazyy"
                        ),

                    2 => array(
                            0 => "My belowed text",
                            1 => "You crazyy"
                        ),

                    10 => array(
                            0 => "My loved quote",
                            1 => "You crazyy"
                        )

                );
    array_shift($array);
    $array = array_values($array);
    echo "<pre>";
    print_r($array);

Output: check the output here https://eval.in/837711

Array
(
    [0] => Array
        (
            [0] => My belowed text
            [1] => You crazyy
        )

    [1] => Array
        (
            [0] => My loved quote
            [1] => You crazyy
        )

)

You can cut the array as many many index as you want

$newArray = array_splice($oldArray, $startIndex, $lengthToSlice);

$array=array(
0 => 'A',
2 => 'B',
4 => 'C',
6 => 'D'
);

unset($array[0]);
$array = array_values($array);
print_r($array);

This is also another solution to this issue using unset

Output:

Array
(
    [0] => B
    [1] => C
    [2] => D
)
