I am using a bulletin board called mybb and came across the following code:-

$settings['setting'] = "setting"

What does it do, google has failed me, because I don't know what to search for exactly.

How would I make use of it?

Answer 1

This statement sets the value of the item in the array $settings identified by key setting to the string "setting".

You would use it like this:-

$settings['setting'] = "setting";

And if, for example, you wanted to echo the value you would do so like this :-

echo $settings['settings'];

Answer 2

I'm going to use different names so that you might see that the keyword 'setting' is in all 3 cases of your code, arbitrary:

$animals = array("cat"=>"mamal","ant"=>"insect");
$animals['cat']="insect";

the first line merely declares two key value pairs within an array called $animals the second line merely sets the value of key 'cat' to "insect".

echo $animals['ant'];

this last code line should print "insect".
