PHP break Statement

With the break statement we can stop the loop even if the condition is still true:

<h4>break Statement</h4>
<p>Stop the loop when $i is 3:</p>
<?php
    $i = 1;

    do {
      if ($i == 3) break;
      echo $i;
      $i++;
    } while ($i < 6);
?>

PHP continue Statement

The continue statement breaks one iteration (in the loop), if a specified condition occurs, and continues with the next iteration in the loop.

<h4>continue Statement</h4>
<p>Stop, and jump to the next iteration if $i is 3:</p>
<?php
    $i = 0;

    do {
      $i++;
      if ($i == 3) continue;
      echo $i;
    } while ($i < 6);
?>
