So I have an array called $links
array(
[0] = array(
'type' => 'thread'
'url' => 'blah blah blah'
),
[1] = array(
'type' => 'media'
'url' => 'blah blah blah'
),
[2] = array(
'type' => 'website'
'url' => 'blah blah blah'
)
);
What I am trying to do is sort this array alphabetically using "type". For this I am using usort()
usort($links, create_function('$b, $a', 'return $a["type"] - $b["type"];'));
The problem is, this is not actually sorting the array... all it does is REVERSE the array. After running through, I get Website > Media > Thread. If I process it a second time, it reverses back to Thread > Media > Website.
The final result should be Media > Thread > Website. Am I missing something? Why is this not sorting correctly?
试试这个,代替:
usort($links, create_function('$a, $b', 'return strcmp($a["type"], $b["type"]);'));
