3.4.5 Break/Continue

PHP Break

• You have already seen the break statement used in an earlier chapter of this tutorial. It was used to "jump out" of a switch statement.
• The break statement can also be used to jump out of a loop.
• This example jumps out of the loop when x is equal to 4:

Example 1: PHP Loops - Break

<?php
for ($x = 0; $x < 10; $x++) {
  if ($x == 4) {
    break;
  }
  echo "The number is: $x <br>";
}
?>

PHP Continue

• The continue statement breaks one iteration (in the loop), if a specified condition occurs, and continues with the next iteration in the loop.
• This example skips the value of 4:

Example 2: PHP Loops - Continue

<?php
for ($x = 0; $x < 10; $x++) {
  if ($x == 4) {
    continue;
  }
  echo "The number is: $x <br>";
}
?>

Break and Continue in While Loop

You can also use break and continue in while loops:

Example 3: PHP Loops - Break in While Loop

<?php
$x = 0;

while($x < 10) {
  if ($x == 4) {
    break;
  }
  echo "The number is: $x <br>";
  $x++;
}
?>

Example 4: PHP Loops - Continue in While Loop

<?php
$x = 0;

while($x < 10) {
  if ($x == 4) {
    $x++;
    continue;
  }
  echo "The number is: $x <br>";
  $x++;
}
?>
