按另一个数组中给定的特定顺序对数组值进行排序

我有这个顺序正确的数组:

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

这些文档位于几个服务器和数据库的不同表中。
在搜索文档的最后,我通常会得到一个具有以下结构但数组中的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,但是它不起作用。我收到一个错误,因为第二个参数必须是整数:

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

研究完本机功能后,

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

如何获取正确的值顺序?

期望的示例,按$ orderDoc ordes和按数字文档排序:

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功能,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

循环订购文档,并使用preg_grep获取以相同字符开头的所有数组项。
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);

$ result:

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:这会保留阵列中的重复项。
您并不是说应该删除它们,但是如果要删除它们,只需在$ result中合并temp之前添加array_unique()
