The foreach statement
The foreach statement expects an array, the keyword as, and a definition of the variables to receive each element. If a single value follows as, such as foreach($array as $value), then with each turn of the loop, the variable named value will be set with the value of the next array element. You may capture the index of the array element if you form the foreach statement like foreach($array as $key=>$value).
