有没有办法转换一个看起来像这样的数组：

Array ( [level-1] => 2 [quarter-1] => 1 [year-1] => 2014 [level-2] => 2 [quarter-2] => 2 [year-2] => 2015 [level-49] => 2 [quarter-49] => 2 [year-49] => 2015 [level-58] => 1 [quarter-58] => 1 [year-58]

并且只取关键字后面的数字以在 sql 表中使用它们。例如，该表如下所示：

 ID 1 Level 2 Quarter 1 Year 2014 
 ID 2 level 2 quater 2 Year 2015
 ID 49 level 2 quarter 2 year 2015

ETC

我试过了

if(!empty($_POST)){
        print_r ($_POST);
        echo "<br/><br/>";
        $s=$_POST;

        echo $abc= implode(',', $s);
        for($a=0;$a<count($s);$a++){
            $ar=explode(',',$abc);
            echo $var=$ar[$a];

        }
  }

但我得到的结果是这样的：

2,1,2014,2,2,2015,2,2,2015...

我还需要出示身份证。但最重要的是我不知道如何解释结果以将它们放入数据库中。

尝试这个 ：

$array = array ( "level-1" => 2, "quarter-1" => 1, "year-1" => 2014, "level-2" => 2, "quarter-2" => 2, "year-2" => 2015, "level-49" => 2, "quarter-49" => 2, "year-49" => 2015, "level-58" => 1, "quarter-58" => 1, "year-58"=>2016);

foreach(array_chunk($array,3,true) as $val){
    foreach($val as $k=>$v){
       if(strpos($k, "level") !== false){
           $temp    = explode("-",$k);
           $id      = $temp[1];
           $level   = $v;
       }
       if(strpos($k, "quarter") !== false){
           $quarter = $v;
       }
       if(strpos($k, "year") !== false){
           $year    = $v;
       }
    }
    echo "ID ".$id." Level ".$level." Quarter ".$quarter." Year ".$year;
    echo "<br>";
}

输出 ：

ID 1 Level 2 Quarter 1 Year 2014
ID 2 Level 2 Quarter 2 Year 2015
ID 49 Level 2 Quarter 2 Year 2015
ID 58 Level 1 Quarter 1 Year 2016

我不知道用 PHP 编码，所以我将向您解释这样做的逻辑。

for(int i=0;i<array.length;i=i+3) {

//get value from array[i]; get the level-x field and retrieve the x value, then extract integers accordingly from it after keywords. In java StringTokenizer can be used for this, or regex etc

//again get value from array[i+1] and extract the integer

//get the value from array[i+2] and do the same as above.

}

如果数组被打乱，您可以将其与 level-x 匹配以获取要插入的确切元组。所以 level-x，x 值充当索引，将所有相关值分组。
