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] => ggggg )  

and my result should be

$test=Array ([chemical] => asdasd [chemical_hazards] => ggggg [solution] => good)  

Could you tell me how to implement this?

Answer 1

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

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