Add values to an associative array in PHP

Question

I want to append an element to to end of an associative array.

For example, my array is

$test=Array ([chemical] => asdasd [chemical_hazards] =>         


        

Answer 1

You can do this with PHP's array_merge function.

$test = array('chemical' => 'asdasd', 'chemical_hazards' => 'ggggg'); 
$test2 = array('solution' => 'good');
$result = array_merge($test, $test2);
var_dump($result);

Answer 2

Just add it like you would with a non-associative array:

$test = array('chemical' => 'asdasd', 'chemical_hazards' => 'ggggg'); //init
$test['solution'] = 'good';
