The unshift() method adds new elements to the beginning of an array.
You can use the end() function in PHP to get the last element of any PHP array. It will set the internal pointer to the last element of the array and return its value.
Definition and Usage. The array_push() function inserts one or more elements to the end of an array. Tip: You can add one value, or as many as you like. Note: Even if your array has string keys, your added elements will always have numeric keys (See example below).
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
)
In case of an associative array or numbered array where you do not want to change the array keys:
$firstItem = array('foo' => 'bar');
$arr = $firstItem + $arr;
array_merge does not work as it always reindexes the array.
For an associative array you can just use merge.
$arr = array('item2', 'item3', 'item4');
$arr = array_merge(array('item1'), $arr)
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'
]
