Question

I have a question about the general functionality of PHP that I haven’t been able to get a good, clean, simple answer on.

Say I have a class, student. And I create an array called Students that contains instances of the class student. How would I go about iterating through that array and pulling, say, StudentID off each of the student class instances? Thanks for the support!

Answer 1

If I understand correctly, you have a class like this:

class Student {
    public $StudentId = 0;
    public function __construct($id) {
        $this->StudentId = $id;
    }
}

And an array like this:

$students = array(
    new Student(1),
    new Student(2),
    ....
);

To get the StudentId of each, simply iterate through the array like any other normal array iteration:

foreach ($students as $student) {
    $id = $student->StudentId;
}
