how to insert a new key in an array php code example

Example 1: insert key-value pair into array php

// If you are creating new array then try this :
$arr = array("key" => "value");

// And if array is already created then try this :
$arr["key"] = "value";

Example 2: php insert in array

$original = array( 'a', 'b', 'c', 'd', 'e' );
$inserted = array( 'x' ); // not necessarily an array, see manual quote

array_splice( $original, 3, 0, $inserted ); // splice in at position 3
// $original is now a b c x d e
