Add to an Associative Array in PHP
Let's say we have the following associative array:
<?php
$arr = ['a' => 1, 'b' => 2, 'c' => 3];
?>
Let's add an element with the key 'd'
and the value 4 to it:
<?php
$arr = ['a' => 1, 'b' => 2, 'c' => 3];
$arr['d'] = 4; // add a new element to the array
var_dump($arr);
?>
Code execution result:
['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4]
