主要就是利用数组的key进行排序，然后按照key排序的数组在循环原来的数组即可。
打印的结果如下：
Array ( [0] => Array ( [volume] => 67 [edition] => 2 ) [1] => Array ( [volume] => 86 [edition] => 1 ) [2] => Array ( [volume] => 85 [edition] => 6 ) [3] => Array ( [volume] => 98 [edition] => 2 ) [4] => Array ( [volume] => 86 [edition] => 6 ) [5] => Array ( [volume] => 67 [edition] => 7 ) ) Array ( [0] => 67 [1] => 86 [2] => 85 [3] => 98 [4] => 86 [5] => 67 ) ===== Array ( [3] => 98 [4] => 86 [1] => 86 [2] => 85 [5] => 67 [0] => 67 ) Array ( [3] => Array ( [volume] => 98 [edition] => 2 ) [4] => Array ( [volume] => 86 [edition] => 6 ) [1] => Array ( [volume] => 86 [edition] => 1 ) [2] => Array ( [volume] => 85 [edition] => 6 ) [5] => Array ( [volume] => 67 [edition] => 7 ) [0] => Array ( [volume] => 67 [edition] => 2 ) )
