Each student’s information, such as name, age, and grades, can be stored in an individual array. With a multidimensional array, you can easily access and manipulate specific elements within the array by specifying the appropriate indices at each level.įor example, consider a multidimensional array representing a student database. Using a multidimensional array is especially useful when dealing with structured data, such as employee records, product details, or any other scenario where you want to group related information together. For example, a two-dimensional array is the most common type, with rows and columns, but you can have three-dimensional arrays, four-dimensional arrays, and so on, depending on the complexity of your data. The depth or number of dimensions in a multidimensional array is not limited and can be extended based on your needs. This nesting of arrays creates a multi-level structure. Each element in the array represents a row, and within each row, there can be additional arrays representing columns or attributes. To visualize a multidimensional array, you can think of it as a matrix or a table. It is a way to organize data in a hierarchical structure, allowing for more complex and structured data representation. Here is an example.In PHP, a multidimensional array is an array that contains one or more arrays as its elements. One for loop can be kept inside another for loop and we can generate different scripts using nested loops. $no=count($a) // Number of elements in array We can get the number of elements and use that in our condition checking. This is not a good idea as the count() function returns the same value in each iteration all the time. Here we are counting number of elements in array in each iteration. We can get number of elements in an array by using count(). Read how to display elements of an array Speed of looping This will list all the values of the array from starting to end. So we need not call the reset() again( Reset() rewinds array's internal pointer to the first element. Once the foreach function is called the array pointer will reset to the first element of the array. While handling PHP Arrays foreach function is required to display the elements of an array. If the condition to check is never meet then it will be an infinite loop execution and PHP execution will hang or stop after reaching maximum execution time. We can reduce the step value in each step of iteration. Similarly $i -=10 is same as $i=$i-10 Decrement step value in loop The If condition inside the for loop will exit the loop when the value of $i exceeds 5 ( that is when it equals to 6)Ĭontinue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.Ībove code will print 1 to 10 except the number 5. Check the ouput just outside the for loop.Įcho " Value of \$i Outside the loop: ".$i īy using break we can exit the loop without completing the total required loopings (early exit). For and foreach loop in PHP with break statement and creating patterns using nested for loopsĮxpr3 is executed at the end of the loop.
