while (condition)
        {
        code to be executed;
        }

    /The do...while statement will always execute the block of code once, it will then check the condition, and repeat the loop while the condition is true/
    
       do
      {
       code to be executed;
        }
       while (condition);

The idea of a loop is to do something over and over again until the task has been completed.
    In PHP, we have the following looping statements:

        * while - loops through a block of code while a specified condition is true
        * do...while - loops through a block of code once, and then repeats the loop as long as a specified condition is true
        * for - loops through a block of code a specified number of times
        * foreach - loops through a block of code for each element in an array

    The while loop executes a block of code while a condition is true.
