Loops in PHP

Loops are used to execute a block of code repeatedly. PHP supports various types of loops.

For Loop

The for loop is used when you know how many times the loop should run:

      
        <?php
          for ($i = 1; $i <= 5; $i++) {
            echo "Number: $i 
";
          }
        ?>

While Loop

The while loop runs as long as a condition is true:

      
        <?php
          $i = 1;
          while ($i <= 5) {
            echo "Number: $i 
";
            $i++;
          }
        ?>
