How to create array in PHP with strings from another array as position names?

Question

Basically what I'm trying to do is create an array that has strings for their position names, such as:

$types = [
    "Methods" => array(),
    "Systems" => array(),
    "Equipment" => array()
]

This is what var_dump($types) results in:

array(3) { ["Methods"]=> array(0) { } ["Systems"]=> array(0) { } ["Equipment"]=> array(0) { } } 

However, instead of declaring $types like this, I want to have an array $list ...

$list = ['Foo', 'Bar', 'Baz', ...];

...that generates an array $types ...

$types = ["Foo" => array(), "Bar" => array(),"Baz" => array(), ...]

Is it possible? I have tried doing array_push($types, $list) but that just copies the the string array into the last position of $types

Answer 1

使用array_fill_keys函数

$types = array_fill_keys($list, []);
