How do I remove an element from an array and insert into another position in PHP?
Question by deltanovember
For example suppose I have
$input = array(0, 1, 2, 3, 4, 5, 6, 7);
How would I remove element 5 and insert at position 2 leaving me with
0, 1, 5, 2, 3, 4, 6, 7
Answer by Starx
$input = array(0, 1, 2, 3, 4, 5, 6, 7);
array_splice($input, 2, 0, array($input[5])); //Place the a new array in the 3rd place of array
unset($input[6]); //remove the fifth element
array_splice($input, 0, 0); //to update the indexes
echo "<pre>".print_r($input,1)."</pre>"; //to view the array
Method without the need to unset and rearrange the index
$input = array(0, 1, 2, 3, 4, 5, 6, 7);
array_splice($input, 2, 0, array_splice($input,5,1));
Output
Array
(
[0] => 0
[1] => 1
[2] => 5
[3] => 2
[4] => 4
[5] => 5
[6] => 6
[7] => 7
)
