3. Looping Statements in PHP

Loops are used to execute a block of code repeatedly.

3.1 for Loop Used when the number of iterations is known.

        for ($i = 1; $i <= 5; $i++) {
          echo $i . "<br>";
        }

3.2 while Loop Executes code while condition is true.

        $i = 1;
        while ($i <= 5) {
          echo $i . "<br>";
          $i++;
        }

3.3 do–while Loop Executes code at least once, even if condition is false.

        $i = 1;
        do {
          echo $i . "<br>";
          $i++;
        } while ($i <= 5);

3.4 foreach Loop Used to iterate through arrays.

        $subjects = array("HTML", "CSS", "PHP");
        foreach ($subjects as $sub) {
          echo $sub . "<br>";
        }
