PHP，继续；在 foreach(){ foreach(){

PHP, continue; on foreach(){ foreach(){

提问by Merianos Nikos

Is there a way to continue on external foreach in case that the internal foreach meet some statement ?

如果内部 foreach 遇到某些语句，有没有办法继续外部 foreach？

In example

例如

foreach($c as $v)
{
    foreach($v as $j)
    {
        if($j = 1)
        {
            continue; // But not the internal foreach. the external;
        }
    }
}

Try this, should work:

试试这个，应该工作：

continue 2;

From the PHP Manual:

来自 PHP 手册：

Continue accepts an optional numeric argument which tells it how many levels of enclosing loops it should skip to the end of.

Continue 接受一个可选的数字参数，它告诉它应该跳到结束的封闭循环的级别。

There are two solutions available for this situation, either use breakor continue 2. Note that when using break to break out of the internal loop any code after the inner loop will still be executed.

有两种解决方案可用于这种情况，使用break或continue 2。请注意，当使用 break 跳出内部循环时，内部循环之后的任何代码仍将被执行。

foreach($c as $v)
{
    foreach($v as $j)
    {
        if($j = 1)
        {
            break;
        }
    }
    echo "This line will be printed";
}

The other solution is to use continuefollowed with how many levels back to continue from.

另一种解决方案是使用continue后跟从多少个级别返回继续。

foreach($c as $v)
{
    foreach($v as $j)
    {
        if($j = 1)
        {
            continue 2;
        }
    }
    // This code will not be reached.
}

This will continue to levels above (so the outer foreach)

这将继续高于（因此外部 foreach）

 continue 2

<?php
foreach($c as $v)

    foreach($v as $j)
    {
        if($j = 1)
        {
            continue 2; // note the number 2
        }
    }
}
?>

Try breakinstead of continue.

尝试break代替continue.

You can follow breakwith an integer, giving the number of loops to break out of.

你可以跟break一个整数，给出要跳出的循环数。

回答by Your Common Sense

you have to use breakinstead of continue, if I get you right

break如果我说得对，你必须使用而不是继续

Here I wrote an explanation on the matter: What is meant by a number after "break" or "continue" in PHP?
