通过多个阵列PHP循环 [英] php looping through multiple arrays

问题描述

好了，所以我有两个数组

okay so I have two arrays

$array_one([a]=>2,[b]=>1,[c]=>1);
$array_two([a]=>1,[b]=>2,[c]=>1);

我希望能够遍历这两个阵列同时这样我就可以进行简单的比较。我看着使用foreach循环，但我只能一次处理信息的一个数组。我又看了看合并的阵列，但我看不到这样做的使用，因为我同时需要键值，以使比较。没有任何人有一个解决这个问题？我AP preciate您先进的时间。

I want to be able to loop through both of these arrays simultaneously so I can make simple comparisons. I looked at using a foreach loop but I can only process the information one array at a time. I also looked at merging the arrays but I can not see the use in doing this since I need both the keys and values to make the comparisons. does anyone have a solution to this problem? I appreciate your time in advanced.

要具体到我想要的东西攀比到这个程度。

to be specific on the comparisons i want to something to this extent

if ($keyone == $keytwo && $valuetwo <= $valueone)
{
   print_r ($array_two);
}

有没有可能使用递归循环，而不是使用和迭代循环？

Would it be possible to use recursion to loop instead of using and iterative loop?

推荐答案

如果他们有相同的键就可以使用的 array_keys ：

If they have the same keys you can just loop through the keys and use them to index the arrays using array_keys:

foreach(array_keys($array_one) as $key) {
    // do something with $array_one[$key] and $array_two[$key]
}

如果你担心某些键不存在，你可以尝试（例如） array_key_exists（$键，$ array_two）。

If you're worried about some keys not existing you can try (e.g.) array_key_exists($key,$array_two).
