Question

是否有一种简单的方法可以使用为此任务创建的变量数组对数组进行排序？例如：

$fruits [
   'Apple' => '12',
   'Cherry' => '10',
   'Lemon' => '34', 
   'Peach' => '6'
]

$order [
   1 => 'Peach',
   2 => 'Other',
   3 => 'Lemon',
   4 => 'Other2',
   5 => 'Apple',
   6 => 'Cherry',
   7 => 'Other3'
]

我想返回这种数组：

$ordered_fruits [
   'Peach' => '6',
   'Lemon' => '34',
   'Apple' => '12',
   'Cherry' => '10'
]

Answer 1

$ordered_fruits = array();
foreach($order as $value) {

   if(array_key_exists($value,$fruits)) {
      $ordered_fruits[$value] = $fruits[$value];
   }
}

Answer 2

用php函数制作：

$new = array_filter(array_replace(array_fill_keys($order, null), $fruits));

Answer 3

试试这个：

$fruits = array(
   'Apple' => '12',
   'Cherry' => '10',
   'Lemon' => '34', 
   'Peach' => '6'
);

$order = array(
   1 => 'Peach',
   2 => 'Other',
   3 => 'Lemon',
   4 => 'Other2',
   5 => 'Apple',
   6 => 'Cherry',
   7 => 'Other3'
);

$result = array();
foreach ($order as $key => $value) {
  if ( array_key_exists($value, $fruits) ) {
    $result[$value] = $fruits[$value];
  }
}
print_r($result );

Answer 4

排序技巧：

$result = array();

foreach($order as $value){
    if(array_key_exists($value, $fruits)){
        $result[$value] = $fruits[$value];
    }
}

<强>结果

print_r($result);

Array
(
    [Peach] => 6
    [Lemon] => 34
    [Apple] => 12
    [Cherry] => 10
)

PHP - 使用另一个数组排序数组
