Core PHP: The break Statement (5.15)

The break Statement

As discussed in the previous lesson, the break statement is used to break out of the switch when a case is matched.
If the break is absent, the code keeps running. For example:

$x=1;
switch ($x) {
  case 1:
    echo "One";
  case 2:
    echo "Two";
  case 3:
    echo "Three";
  default:
    echo "No match";
}

//Outputs "OneTwoThreeNo match"

Break can also be used to halt the execution of for, foreach, while, do-while structures.

The break statement ends the current for, foreach, while, do-while or switch and continues to run the program on the line coming up after the loop.
A break statement in the outer part of a program (e.g., not in a control loop) will stop the script.
