The value will be assigned by reference in such scenario. In case you want to modify array elements within the loop, precede $value with address operator (&). Just like the first variant, the internal pointer will advance to the next item in the array until it reaches the end of the array. The second variant of the foreach loop assigns the current element’s key to $key variable and value to the $value variable. And the internal pointer of an array moves to the next item which you will get in the next iteration. PHP will assign the value of the current array element to the variable $value every iteration. The first variant loops across the array ‘array_expression’. PHP foreach can be written in 2 ways: foreach ( array_expression as $value)Īnd foreach (array_expression as $key => $value) Example II of foreach loop for multidimensional arrayįirst, let’s start off with the syntax.Example I of foreach loop for multidimensional array.Example of foreach loop and var_dump function.
