显示对象按数组排列

Question

I have an object student which has variables like student->name , student->age , student->marks , student->id

I have tried this : i have done this to get sorted array of ids

foreach($student as $s){
array_push($student_id_array,$s->id) }
sort($student_id_array);

So i have the array of sorted id of student, but how can i display 100 instances of $student in the same order a $student_id_array ?

Answer 1

This will sorts all your $students array based on each $student->id:

$stud = array (
                (object)array('name' => 'John Doe', 'id' => 1),
                (object)array('name' => 'Jane Doe', 'id' => 3),
                (object)array('name' => 'Luke Will', 'id' => 4),
                (object)array('name' => 'Eric Sting', 'id' => 2)
            );
$Students = array();
foreach($stud as $s){
     $Students[$s->id] = $s;
}
ksort($Students);

foreach($Students as $s){
     echo $s->name; 
}
