Do While Loop Php

Learn how the PHP dowhile loop ensures code execution at least once before condition checking. Dive into syntax, examples, and practical use cases in this comprehensive guide.

PHP do while loop is very similar to the while loop, but it always executes the code block at least once and furthermore as long as the condition remains true. Syntax lt?php do code to be executed while condition ?gt

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

Difference Between while and dowhile Loop. The while loop differs from the do-while loop in one important way with a while loop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never be executed.. With a do-while loop, on the other hand, the loop will always be executed once, even if the

A do-while loop in PHP is a control structure that repeatedly executes a block of code at least once, and then continues to execute the code as long as the condition remains true. Unlike the while loop, which checks the condition before the first iteration, the do-while loop checks the condition after the first iteration, ensuring that the loop

Note In a dowhile loop the condition is tested AFTER executing the statements within the loop. This means that the dowhile loop will execute its statements at least once, even if the condition is false. See example below.

The do-while loop in PHP or any other programming languages is just an opposite of the while loop. Its function is exactly like an ordinary while loop, with only one key difference The while loop evaluates the condition before executing the code contained in the loop body. If the condition evaluates to false on the first check, the code inside

Introduction to PHP dowhile loop statement The PHP dowhile statement allows you to execute a code block repeatedly based on a Boolean expression. 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 Do While Loop in PHP executes a block of code at least once before checking the condition. If the condition remains true, the loop continues execution. Syntax do Code to be executed while condition The do block runs first, and then the while statement checks if the loop should continue.

do-while PHP 4, PHP 5, PHP 7, PHP 8 do-while loops are very similar to while loops, except the truth expression is checked at the end of each iteration instead of in the beginning. The main difference from regular while loops is that the first iteration of a do-while loop is guaranteed to run the truth expression is only checked at the end of the iteration, whereas it may not necessarily
