In this tutorial, you shall learn how to iterate through an array in PHP using For loop, with the help of example programs. PHP – Iterate through an array using For Loop To iterate through the elements of an array, we can useFor loop. We initialize an index variable with 0, increment...
Loop through and print all the values of an associative array: <?php $age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43"); foreach($ageas$x=>$x_value) { echo"Key=". $x .", Value=". $x_value; echo""; } ?> Try it...

Using loops, such as the PHP for Loop, you can access each element of the array sequentially, perform operations on them, and automate repetitive tasks efficiently. Common array functions in PHP PHP provides a variety of built-in array functions that enable you to manipulate and operate on ...

Comparing this code to the imperative version, you see that you’ve freed yourself from the responsibility of properly managing a loop counter and array index access; put simply, the more code you have, the more places there are for bugs to occur. Also, standard loops are not reusable ...
