How to insert an item at the beginning of an array in PHP?

Question

I know how to insert it to the end by:

$arr[] = $item;

But how to insert it to the beginning?

Answer 1

Insert an item in the beginning of an associative array with string/custom key

<?php

$array = ['keyOne'=>'valueOne', 'keyTwo'=>'valueTwo'];

$array = array_reverse($array);

$array['newKey'] = 'newValue';

$array = array_reverse($array);

RESULT

[
  'newKey' => 'newValue',
  'keyOne' => 'valueOne',
  'keyTwo' => 'valueTwo'
]

Answer 2

This will help

array_unshift();

Answer 3

Use array_unshift($array, $item);

$arr = array('item2', 'item3', 'item4');
array_unshift($arr , 'item1');
print_r($arr);

will give you

Array
(
 [0] => item1
 [1] => item2
 [2] => item3
 [3] => item4
)

Answer 4

For an associative array you can just use merge.

$arr = array('item2', 'item3', 'item4');
$arr = array_merge(array('item1'), $arr)

Answer 5

Use function array_unshift

Answer 6

With custom index:

$arr=array("a"=>"one", "b"=>"two");
    $arr=array("c"=>"three", "d"=>"four").$arr;

    print_r($arr);
    -------------------
    output:
    ----------------
    Array
    (
    [c]=["three"]
    [d]=["four"]
    [a]=["two"]
    [b]=["one"]
    )
