Write A Php Code Using Do While Loop

How to Use a do-while Loop in PHP. Writing a Standard do-while Loop Breaking Out of a do-while Loop Using continue Inside a do-while Loop Conclusion do-while Loop Syntax. The syntax for a do while loop is pretty straightforward and is somewhat similar to a regular while loop. The code block starts with quotdoquot, followed by the curly brackets.

There is one major difference you should be aware of when using the do--while loop vs. using a simple while loop And that is when the check condition is made. In a do--while loop, the test condition evaluation is at the end of the loop. This means that the code inside of the loop will iterate once through before the condition is ever evaluated.

As you can see, the code block to be executed is enclosed in the do keyword, and the condition to be checked is placed after the while keyword. Usage of do-while Statement. The do-while loop is used in PHP when you want to execute the code block at least once, and then repeat the code block until the given condition is true.

3. How the do-while Loop Works. The code inside the do block is executed once. After the code block is executed, the condition is evaluated. If the condition is true, the loop starts again if false, the loop terminates. This guarantees the code inside the do block will always execute at least once. 4. Examples of Using the do-while Loop

Here's the syntax of the PHP do-while statement lt?php do statement while expression Code language PHP php Unlike the while statement, PHP evaluates the expression at the end of each iteration. It means that the loop always executes at least once, even the expression is false before the loop enters. The following flowchart

Do While Loop In PHP. This article discusses use of the PHP do while loop with examples, how it differs from other loop types, and how it is used.. Similar to the while loop, a do-while loop executes code at least once, regardless of whether the condition is true or false.. It is useful when you need to run at least once a particular block of code, such as when validating user input or

In a do-while loop, the loop is executed at least once when the given expression is quotfalsequot. The first iteration of the loop is executed without checking the condition. Flowchart of the do-while loop Syntax do Code is executed while if the condition is true Example 1 The following code demonstrates the do..while statement. PHP

This makes the Do While Loop useful in menu-driven applications, authentication prompts, and input validation.. Advantages amp When to Use Do While Loop in PHP Key Benefits of Using Do While Loop in PHP. Ensures at Least One Execution The loop runs at least once before checking the condition.

The main difference between While and Do-While loop is that the do-while loop checks the condition at the end, whereas the while loop checks the condition at the beginning. Therefore, for the do-while loop, the block of code will execute at least once even if the condition in do-while is false. PHP do while loop syntax do Code to be
