![]() ![]() by using the length property to get the length of the array and then using it as the max operator. You can also use a simple for loop to manipulate arrays e.g. The foreach will loop through each element of the given array. The PHP foreach loop is used to manipulate arrays. See online demo and code Why we use PHP foreach? See the demo and code by clicking the link or image below: To see the difference between array before and after assigning the new values, the array is displayed by using the print_r function, which is used to display the visual representation of the given array. Inside curly braces, we assigned new values to the array elements. ![]() ![]() Then we simply used a foreach loop to display array element values.Īfter that, we used another foreach loop where the $value_of_element is preceded by “&”. In this example, we have created a numeric array of five elements. To make it clearer, see the following example. For that, use the “&” before the “$” for the value variable e.g. You can modify the values of the elements of the given array by using the foreach loop. See online demo and code An example to change array element values in foreach loop The $salaries array is defined followed by three employee names (acting as keys) and salaries as values. For that, we have created an associative array of three elements. In this example, we will use the other way of using the foreach loop i.e. See online demo and code An example with array key and values See the example and code by clicking the image or link below: Inside the foreach loop, we used PHP echo statement to display the array values. After that, a foreach PHP loop is used to iterate through that array. In this example, we have created an array of five elements with numeric values. Both of these methods of using foreach are explained in the last part of this tutorial, after the examples below.Įxample of using foreach loop with numeric array ![]()
