数组排序 - php用系统函数将一个数组按另一个数组的值进行排序

<code>array (size=6)
  0 => string 'id' (length=2)
  1 => string 'name' (length=4)
  2 => string 'identityId' (length=10)
  3 => string 'phone' (length=5)
  4 => string 'email' (length=5)
  5 => string 'schoolId' (length=8)
array (size=6)
  'id' => string '唯一标识' (length=12)
  'identityId' => string '身份证' (length=9)
  'phone' => string '手机号' (length=9)
  'email' => string '邮箱' (length=6)
  'name' => string '姓名' (length=6)
  'schoolId' => string '学校' (length=6)</code>

<code><?php

    'schoolId' => '学校'
];

var_dump(array_merge(array_flip($a), $b));</code>

<code class="php">$arr1 = array(
    'id',
    'name',
    'identityId',
    'phone',
    'email',
    'schoolId'

    'phone' => '手机号',
    'email' => '邮箱',
    'name' => '姓名',
    'schoolId' => '学校',
);
array_multisort($arr1,SORT_DESC,$arr2);
print_r($arr2);
// 结果为：
Array
(
    [schoolId] => 学校
    [email] => 邮箱
    [identityId] => 身份证
    [phone] => 手机号
    [id] => 唯一标识
    [name] => 姓名
)
</code>

<code>$c[$v] = $b[$v];</code>

<code>$c = array();
foreach ($a as $value) $c[$value] = $b[$value];
print_r($c);</code>
