PHP Loops

Loops in PHP are used to execute a block of code multiple times. There are different types of loops like for, while, foreach, and do-while.

For Loop

The for loop repeats a block of code a specific number of times:

      
        <?php
          for ($i = 0; $i < 5; $i++) {
            echo "Number: $i <br>";
          }
        ?>
      
    

While Loop

The while loop repeats a block of code as long as a condition is true:

      
        <?php
          $i = 0;
          while ($i < 5) {
            echo "Number: $i <br>";
            $i++;
          }
        ?>
