按另一个数组中给定的特定顺序对数组值进行排序

Question

我有这个顺序正确的数组：

$orderDoc = array("ORT", "TRI", "CONT", "RMI");

这些文件在几个服务器和数据库的不同表中。
在搜索文档结束时，我通常会得到一个具有以下结构但元素处于混乱状态的数组：

//模拟变量：

$FindDoc= array("RMI0000191","ORT0000379","ORT0000391","ORT0000392","ORT0000390","CONT0000274","CONT0000275","RMI0000192","ORT0000391");

输出：

array(10) {
  [0]=>
  string(10) "RMI0000191"
  [1]=>
  string(10) "ORT0000379"
  [2]=>
  string(10) "ORT0000391"
  [3]=>
  string(10) "ORT0000392"
  [4]=>
  string(10) "ORT0000390"
  [5]=>
  string(11) "CONT0000274"
  [6]=>
  string(11) "CONT0000275"
  [7]=>
  string(10) "RMI0000192"
  [8]=>
  string(10) "ORT0000394"
  [9]=>
  string(10) "TRI0000170"
}

我尝试使用它，但它不起作用。我得到一个错误，因为第二个参数需要是整数：

$FindDoc=asort($FindDoc,$orderDoc );

在调查 none 这个本机函数工作之后：

PHP - Sort Functions For Arrays
In this chapter, we will go through the following PHP array sort functions:

sort() - sort arrays in ascending order
rsort() - sort arrays in descending order
asort() - sort associative arrays in ascending order, according to the value
ksort() - sort associative arrays in ascending order, according to the key
arsort() - sort associative arrays in descending order, according to the value
krsort() - sort associative arrays in descending order, according to the key

如何获得值的正确顺序？

预期示例，按 $orderDoc ordes 和数字文档排序：

array(10) {
  [0]=>
  string(10) "ORT0000379"
  [1]=>
  string(10) "ORT0000390"
  [2]=>
  string(10) "ORT0000391"
  [3]=>
  string(10) "ORT0000392"
  [4]=>
  string(10) "ORT0000394"
  [5]=>
  string(10) "TRI0000170"
  [6]=>
  string(11) "CONT0000274"
  [7]=>
  string(11) "CONT0000275"
  [8]=>
  string(10) "RMI0000191"
  [9]=>
  string(10) "RMI0000192"
}

更新我尝试使用自定义函数但出现一些错误：

foreach ($FindDoc as $StructureMember) {
    $key = array_search($StructureMember, function ($StructureMember, $orderDoc ) {
        return (strpos($StructureMember, $orderDoc ));
    });
    $result[$key] = $StructureMember;
}
$FindDoc = $result;

输出：

Warning: array_search() expects parameter 2 to be array, object given in C:\xampp\htdocs\class\class.docinfo.php on line 15

循环 orderdoc 并使用 preg_grep 获取所有以相同字符开头的数组项。
然后对返回的数组进行排序，并将它们合并到结果数组中。

$orderDoc = array("ORT", "TRI", "CONT", "RMI");

$FindDoc= array("RMI0000191","ORT0000379","ORT0000391","ORT0000392","ORT0000390","CONT0000274","CONT0000275","RMI0000192","ORT0000391");

$result =[];
foreach($orderDoc as $doc){
    $temp = preg_grep("/^". preg_quote($doc) . "/", $FindDoc);
    sort($temp);
    $result = array_merge($result, $temp);
}

var_dump($result);

$结果：

array(9) {
  [0]=>
  string(10) "ORT0000379"
  [1]=>
  string(10) "ORT0000390"
  [2]=>
  string(10) "ORT0000391"
  [3]=>
  string(10) "ORT0000391"
  [4]=>
  string(10) "ORT0000392"
  [5]=>
  string(11) "CONT0000274"
  [6]=>
  string(11) "CONT0000275"
  [7]=>
  string(10) "RMI0000191"
  [8]=>
  string(10) "RMI0000192"
}

注意：这会保留数组中的重复项。
你不是说应该删除它们，但如果你想删除它们，只需在将 temp 合并到 $result

之前添加 array_unique()

按另一个数组中给定的特定顺序对数组值进行排序
