php foreach returning value=>value instead of key=>value

Question

I have an object, when I do a var_dump this is the output:

array(7) {
  ["foodRaw"     ]=>  string(9) "000000000"
  ["broodRaw"    ]=>  string(9) "111000000"
  ["food"        ]=>  int(0)
  ["brood"       ]=>  int(3)
  ["size"        ]=>  int(0)
  ["foodHarvest" ]=>  int(0)
  ["broodHarvest"]=>  int(0)
}

When I do

foreach ($data AS $key => $Value){ 
    $this->{$key} = $Value;
    echo $this->{$key} . " = " . $Value . "<br>
    ";
}

IT doesn't behave like I expect, It ouputs this nonsense:

000000000 = 000000000<br>
111000000 = 111000000<br>
0 = 0<br>
3 = 3<br>
0 = 0<br>
0 = 0<br>
0 = 0<br>

Does anybody know the logic behind this behavior?

Well sure. You are setting:

$this->{$key} = $Value;

So now those both have the same value. If you immediately echo them:

echo $this->{$key} . " = " . $Value

You'll get the same output for both! This is like setting $a = $b and then being surprised when echo $a = $b shows you the same value for both.

I think what you want is:

echo $key . " = " . $Value
