php - Convert array of keys to associative array -

i have array of data so

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

i need convert so

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

i found out array_flip gives me

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

what can there? clean php way this?

array_combine() way go

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