A recursive algorithm repeatedly calls itself. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Recursive loop through multidimensional PHP arrayĪs mentioned already, recursive algorithms are not concerned with the complexity of a multidimensional array, making them more robust and practical in actual scenarios. ![]() So it iterates the arrays on the same level as. The second loops check if the element is an array and loops through it if true. The second loop accesses elements inside the ]. The outermost foreach loop accesses the elements on the same level of ]. $arr = [īecause the associative array is 3D, there’ll be three foreach loops. Let’s take a three-dimensional associative array in PHP. How to print a multidimensional array in PHP using for loop So, it is always better to resort to recursive algorithms for more arrays that are more complex and inconsistent in terms of structure and complexity. Generally, using more than two nested loops is not a good practice. So, a foreach loop is helpful if the maximum level of a multidimensional array is known beforehand. Note that the code complexity increases as the loop nesting increases. A three-dimensional array would require two nested loops. The foreach loop nesting is directly related to nesting in a multidimensional array. Can we use the foreach loop for multidimensional arrays in PHP?Ī multidimensional array has nested levels of arrays. The array in the example is linear, but what if it is multidimensional? How does that affect the foreach loop? Let’s see that next. The foreach loop accesses them by keeping a reference two both as it loops through the array. Let’s review the syntax of the foreach loop through an example. ![]() Look Through PHP Multidimensional Arrays Using the foreach loop Nevertheless, you can read an in-depth article about the loops in PHP. This article answers how to loop through a multidimensional array in PHP, and thus it will focus on the foreach loop. Besides foreach, PHP has for, while, and do-while loops. ![]()
