I have the following multidimensional array
我有以下多维数组
Array
(
[June 2015] => Array
(
[LOW] => Array
(
[0] => 160.50
)
[MEDIUM] => Array
(
[0] => 0.00
)
[HIGH] => Array
(
[0] => 60.80
)
)
[July 2015] => Array
(
[MEDIUM] => Array
(
[0] => 226.00
)
[HIGH] => Array
(
[0] => 263.00
)
[LOW] => Array
(
[0] => 121.96
)
)
)
I need to sort each of the inner arrays by their key so they are in the order LOW, MEDIUM, HIGH (the first is correct by chance).
我需要按其键排序每个内部数组，因此它们的顺序为LOW，MEDIUM，HIGH（第一个是偶然的正确）。
I tried the following code which I took and adjusted from here:
我尝试了以下代码，我从这里开始调整：
function cmp($a, $b){
$a = preg_replace('@^(LOW|MEDIUM|HIGH) @', '', $a);
$b = preg_replace('@^(LOW|MEDIUM|HIGH) @', '', $b);
return strcasecmp($a, $b);
}
foreach($live_quotations as $exp_conversion_date => $Aconversion_likelihood){
foreach($Aconversion_likelihood as $conversion_likelihood => $quotation_values){
uksort($live_quotations[$exp_conversion_date], "cmp");
}
}
but this orders them as HIGH, MEDIUM, LOW (ascending alphabetical). It does not matter if I change the order in the cmp function they are always sorted this way. I don't think I'm understanding this uksort or cmp function correctly. Any help will be great!
但是这会将它们命令为HIGH，MEDIUM，LOW（按字母顺序排列）。如果我改变cmp函数中的顺序并不重要，它们总是以这种方式排序。我不认为我正确理解这个uksort或cmp函数。任何帮助都会很棒！
Thanks

You could use the following comparison function:
您可以使用以下比较功能：
function cmp($a, $b) {
$order = Array( 'LOW' => 0, 'MEDIUM' => 1, 'HIGH' => 2 );
return $order[$a] - $order[$b];
}
Example of this code is here.
