php - 从数组中的数组创建升序数组

Question

我在 PHP 中有这个数组，其中我有一个包含名称和排名的数组中的数组。我希望队伍按顺序排列。即从 1 到 16。

$info = array(  array( "Name"=> "Ayush Mishra", "Rank"=> "1"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "16"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "14"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "15"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "13"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "12"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "11"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "10"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "8"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "9"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "7"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "5"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "4"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "3"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "6"),  
  array( "Name"=> "Ayush Mishra", "Rank"=> "2"),   ); 

我想要上面数组中的这个数组。这是我想要得到的结果数组。

$result = array( 


  array( "Name"=> "Ayush Mishra", "Rank"=> "1"),  
  array( "Name"=> "Teaser", "Rank"=> "2"), 
  array( "Name"=> "Pussel", "Rank"=> "3"),
  array( "Name"=> "Condomso", "Rank"=> "4"),  
  array( "Name"=> "Branite", "Rank"=> "5"),  
  array( "Name"=> "Biknol", "Rank"=> "6"),  
  array( "Name"=> "Fuckita", "Rank"=> "7"),
  array( "Name"=> "James", "Rank"=> "8"),  
  array( "Name"=> "Babita", "Rank"=> "9"),  
  array( "Name"=> "Mathse", "Rank"=> "10"), 
  array( "Name"=> "rohan", "Rank"=> "11"),  
  array( "Name"=> "Alex", "Rank"=> "12"), 
  array( "Name"=> "Peter", "Rank"=> "13"),  
  array( "Name"=> "Gabbar Singh", "Rank"=> "14"),  
  array( "Name"=> "raghav", "Rank"=> "15"), 
  array( "Name"=> "Shivam", "Rank"=> "16"),  


             ); 

我想要上面的数组作为 $info 的结果。请给我将 $info 更改为 $result 的代码。

Answer 1

除此之外别无其他:

function sort_by_rank($a, $b) {
    return $a['Rank'] > $b['Rank'];
}

usort($info, "sort_by_rank");
print_r($info);

输出

如果您想维护原始索引，从您的问题来看这似乎不是必需的，但如果是这样，请使用 uasort 而不是 usort。
