将键数组转换为关联数组

Question

I have an array of data like so

[
 'one', 'two', 'three'
]

I need to convert it like so

[
  'one' => 'one',
  'two' => 'two'
]

I found out about array_flip which gives me

[
   'one' => 0,
   'two' => 0,
   'three' => 0
]

What can I do from there? Any clean PHP way to do this?

Answer 1

array_combine() is the way to go

$a = array('one', 'two', 'three');
$output = array_combine($a, $a);
