$args = array( 'post_type' => 'portfolio' );

$args = array( 'post_type' => 'portfolio' );

This is a php array. An array allows you to find data based on a key. You can define arrays in 2 different ways.

$args = array("value1","value2","value3","value4","value5","value6","value7");
$argsTwo = array( 'post_type' => 'portfolio', 'post_id' => 1, 'post_title' => "My test post" );

$args is a standard array, where values are separated by a comma delimited list. The key is based on it's position in the list starting from 0.

$args[0] would give you the value of "value1" $args[5] would give you the value of "value6"

You can set new values by doing. $args[6] = "My great new value"; // Would set the value of $args[6] to "My great new value" $args[] = "New value"; // adds a new key/value to the end of the array

$argsTwo is a dictionary array. It too is based on a comma delimited list but each delimited section is 2 part. a key and a value. the => delineates the key from the value. "KEY" => "VALUE"

Therefore...

$argsTwo['post_type'] has a value of "portfolio" $argsTwo['post_title'] has a value of "My test portfolio"

Similar to the first array you can set a value by doing $argsTwo['post_title'] = "My new test portfolio title";

And you can add a new key value by doing $argsTwo['post_content'] = "My happy new post content"

Does that make sense?

Hi Nijad Kifayeh, you are correct. I've been doing some researching online and found the same answer as you were given in previous comment. Thanks both. (Y)
