Do-While Loop Function PHP:

PHP Do-While loop method is another type of loop which runs at least once, since this loop checks the condition after executing the code within. We generally use Do-While loop  when the iteration must run at least once despite of the validity of the variable. In Do-While loop we need to initialize the variable first the coding within the loop executes and at last the this loop checks the condition. We should change the value of the variable within the loop.

PHP do while loop Example:

$i=34;

do{

echo "Value of \$i is $i <br/>";

$i++;

}while($i<11);

Output:

Value of $i is 34

Exaplanation:

In the above example, value of $i is not valid but do-while loop runs at least one time despite the validity of the variable.
