如何在不停止 PHP 脚本的其余部分的情况下停止 foreach 循环？

How to stop foreach cycle without stopping the rest of the PHP script?

提问by daGrevis

Having a foreachloop, is it possible to stop it if a certain condition becomes valid?

有一个foreach循环，如果某个条件有效，是否可以停止它？

Example:

例子：

<?php
foreach ($foo as $bar) {

  if (2+2 === 4) {
    // Do something and stop the cycle
  }

}
?>

I tried to use returnand exit, but it didn't work as expected, because I want to continue executing the remaining of the PHP script.

我尝试使用returnand exit，但它没有按预期工作，因为我想继续执行剩余的 PHP 脚本。

Use break:

使用break：

foreach($foo as $bar) {    
    if(2 + 2 === 4) {
        break;    
    }    
}

Break will jump out of the foreachloop and continue execution normally. If you want to skip just one iteration, you can use continue.

Break 会跳出foreach循环，继续正常执行。如果只想跳过一次迭代，可以使用continue.
