foreach($array as $key => $value) { if($value == 5)break; } // 这是一种. // 如果是嵌套的循环,用continue加数字也可以实现 foreach($array as $key => $value) { foreach($value as $key2 => $value2) { if($value == 5)continue 2; } } //只中止第二层 ,第一层继续 foreach($array as $key =&g…
最近几天被这个嵌套搞晕了,还好经过几天的努力终于解决了,特记录下,因为要传两个List集合到jsp页面,还都是在一起输出,发现不能把两个集合放在一个foreach,所以就写了两个foreach来接受,可是问题来了,因为是嵌套,里层foreach的循环次数会被外层的循环次数影响,里层的foreach循环次数总是里层乘以外层的总和,我只想两个foreach循环次数是一样,这样取出的值,才能凑一起,想过在后台把两个集合放一起在传,但是因为是两个不同类型的集合,要么存不进去,要么存进去取出来就有问题了,…

Given a non-negative integer num, repeatedly add all its digits until the result has only one digit. For example: Given num = 38, the process is like: 3 + 8 = 11, 1 + 1 = 2. Since 2 has only one digit, return it. Follow up:Could you do it without any…
