What is do while loop with example?

The do while loop checks the condition at the end of the loop. The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once. An example of such a scenario would be when you want to exit your program depending on the user input.

Example Explained

1. $x = 1; – Initialize the loop counter ($x), and set the start value to 1.
2. $x <= 5 – Continue the loop as long as $x is less than or equal to 5.
3. $x++; – Increase the loop counter value by 1 for each iteration.

Like any other language, loop in PHP is used to execute a statement or a block of statements, multiple times until and unless a specific condition is met. This helps the user to save both time and effort of writing the same code multiple times. PHP supports four types of looping techniques; for loop. while loop.

The do… while loop will always execute the block of code once, it will then check the condition, and repeat the loop while the specified condition is true.

JavaScript while loop examples First, outside of the loop, the count variable is set to 1. Second, before the first iteration begins, the while statement checks if count is less than 10 and execute the statements inside the loop body.

A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement….Here is the difference table:

The foreach loop is mainly used for looping through the values of an array. It loops over the array, and each value for the current array element is assigned to $value, and the array pointer is advanced by one to go the next element in the array.

The keyword break ends execution of the current for, foreach, while, do while or switch structure. When the keyword break executed inside a loop the control automatically passes to the first statement outside the loop. A break is usually associated with the if.

The PHP do-while loop is used to execute a set of code of the program several times….Difference between while and do-while loop.

Following is the syntax of a do…while loop − do { // Statements }while (Boolean_expression); Notice that the Boolean expression appears at the end of the loop, so the statements in the loop execute once before the Boolean is tested.

A do-while loop is a kind of loop, which is a kind of control statement. It is a loop with the test at the bottom, rather than the more usual test at the top.

The Do Until loop keeps iterating while the condition is false and until the condition is true. The Do While loop simply executes as long as the condition is true. Examine the code above and verify that you understand this.

The while and do while loops are generally available in different programming languages. Python also has while loop, however, do while loop is not available. As such, the difference between while and do while loop is the do while loop executes the statements inside it at least once; even the condition fails at first iteration.
