Statements: Break

A break statement can be used to interrupt the iteration of a loop statement and to break-out to the statement immediately following that loop statement. For example:

while (true) {
  if ($done)
    break;  // break out of the while loop

Sometimes it is useful to have an infinite loop from which we can escape when the right condition occurs.

Although a break statement must not attempt to break out of a finally block, a break statement can break out of a construct that is fully contained within a finally block.

A break statement can also affect a non-looping context; it terminates a case in a switch statement.
