Break

Break is a control structure, which ends execution of the current for, foreach, while, do-while or switch structure.

break accepts an optional argument, which tells how many enclosing structures are to be broken out of.

break should not be confused with continue : continue doesn’t work in a switch, like a break does.

<?php

foreach([1,2,3] as $b) {
    // break upon the first even number
    if ($b % 2 == 0) {
        break;
    }

    echo $b;
}

?>
