正如您所看到的，每个id都有7个不同级别的成绩。我的问题是，如何根据最大值确定id选择条件的类id，以便每个id只在一个类中。每个类都有不同的id可接受限制

Answer 1

我会循环数组但首先要做的事情。

将所有行更改为像这样的实数数组

Array ( [id] => Siswa_289 [class] => TSM [value] => 0.93307929758057 )

进入

$myarray [] = Array( [id] => Siswa_289 [class] => TSM [value] => 0.93307929758057 );

然后，您可以使用foreach来浏览数组。

foreach($myarray as $k => $data_r){

// Add your if in here for instance
if($data_r["class"]=="TSM){
    print_r($data_r);
}

}
