PHP provides a way to define objects so that it is possible to iterate through a list of items, such as the statement foreach. By default, all visible properties will be used for iteration.

Example #1 Simple object iteration

<?php
class MyClass
{
    public $var1 = 'value 1';
    public $var2 = 'value 2';
    public $var3 = 'value 3';

    protected $protected = 'protected var';
    private   $private   = 'private var';

    function iterateVisible() {
       echo "MyClass::iterateVisible:\n";
       foreach ($this as $key => $value) {
           print "$key => $value\n";
       }
    }
}

$class = new MyClass();

foreach($class as $key => $value) {
    print "$key => $value\n";
}
echo "\n";


$class->iterateVisible();

?>

The above example will print:

var1 => value 1
var2 => value 2
var3 => value 3

MyClass::iterateVisible:
var1 => value 1
var2 => value 2
var3 => value 3
protected => protected var
private => private var

As the output shows, the foreach has passed through each of the visible variables that can be accessed.

You can use the foreach it works only on arrays and objetos, and will issue an error when trying to use it in a variable with a different data type or an uninitialized variable. 

foreach ($meu_array as $chave => $item_objeto){
    echo "Chave do Array: ".$chave."<br>";
    echo "id: ".$item_objeto->id;
    echo "first_name: ".$item_objeto->first_name;
    // Assim por diante ...
}
