Create multiple Objects from the same class

Question

I've got a very simple question but I don't get it. I've got a class with a few values looking like this:

class test_one{
    private $value1, $value2;

    public function __construct($value1,$value2){
        $this->$value1 = $value1;
        $this->$value2 = $value2;
    }
}

Now I want to create twenty objects of this class.

The Code in C# is looking like this:

ref = new test_one[20];

So my question is: how can I create 20 objects of the same class and save them in a reference so I can adress them by their Index?

You need to use loop

your assigning syntax is wrong

$this->value1 = $value1;$this->value2 = $value2;

You could do something along these lines:

<?php
class test_one{
    private $value1, $value2;

    public function __construct($value1,$value2){
        $this->value1 = $value1;
        $this->value2 = $value2;
    }
}

for($i=1; $i<=20; $i++) {
    $var = "object" . $i;
    $$var = new test_one($value1 = $i, $value2 = $i*$i);
}

 // show, say, object20
 echo '<pre>';
 print_r($object20);
 echo '</pre>';

output:

test_one Object
(
    [value1:test_one:private] => 
    [value2:test_one:private] => 
    [20] => 20
    [400] => 400
)

$value1 = $i, $value2 = $i*$i redundant assignments.

You need a loop, as already said in comments. Simple loop can be:

$i = 0;
while ($i++ < 20) {
    $arr_of_objects[] = new test_one();
}

Also, as already noticed in comments too, assigning values to class properties is done without $:

public function __construct($value1,$value2){
    $this->value1 = $value1;
    $this->value2 = $value2;
    //----^ no $ here
}
