在PHP中中断和继续之间的区别? [英] Difference between break and continue in PHP?

问题描述

break 和 continue ?

推荐答案

break完全结束循环，continue只是将当前迭代作为捷径，然后转到下一个迭代.

break ends a loop completely, continue just shortcuts the current iteration and moves on to the next iteration.

while ($foo) {   <--------------------┐
    continue;    --- goes back here --┘
    break;       ----- jumps here ----┐
}                                     |
                 <--------------------┘

它的用法如下:

while ($droid = searchDroids()) {
    if ($droid != $theDroidYoureLookingFor) {
        continue; // ..the search with the next droid
    }

    $foundDroidYoureLookingFor = true;
    break; // ..off the search
}
