Question

I’m not 100% but this ($settings) would be called an array in php:

$setting;

$setting['host'] = "localhost";
$setting['name'] = "hello";

but what’s the name for this that’s different to the above:

$settings = array("localhost", "hello");

Also from the first example how can i remove the element called name?

(please also correct my terminology if I have made a mistake)

I’m not 100% but this ($settings)
would be called an array in php:

You should be 100% sure, they are 🙂

but what’s the name for this that’s
different to the above:

This:

$setting['host'] = "localhost";
$setting['name'] = "hello";

And this are different ways of declaring a php array.

$settings = array("localhost", "hello");

In fact this is how later should be to match the first one with keys:

$settings = array("host" => "localhost", "name" => "hello");

Also from the first example how can i
remove the element called name?

You can remove with unset:

unset($setting['name']);

Note that when declaring PHP array, do:

$setting = array();

Rather than:

$setting;

Note also that you can append info to arrays at the end by suffixing them with [], for example to add third element to the array, you could simply do:

$setting[] = 'Third Item';
