遍历在PHP中一个复杂的关联数组 [英] Iterating over a complex Associative Array in PHP

问题描述

有没有一种简单的方法来遍历这个结构在​​PHP关联数组：

Is there an easy way to iterate over an associative array of this structure in PHP:

阵列 $搜索有编号的指数，与4和5之间的关联部件。所以，我不仅需要遍历 $搜索[0] 到 $搜索[N] ，也 $搜索[0] [PART0] 到 $搜索[N] [PARTN] 。难的是，不同的指数具有部分不同的数字（有些人可能会丢失一个或两个）。

The array $searches has a numbered index, with between 4 and 5 associative parts. So I not only need to iterate over $searches[0] through $searches[n], but also $searches[0]["part0"] through $searches[n]["partn"]. The hard part is that different indexes have different numbers of parts (some might be missing one or two).

这在某种程度上是很好，整洁，可以理解这样的想法？

Thoughts on doing this in a way that's nice, neat, and understandable?

推荐答案

我不知道我理解的问题。你知道 的foreach 循环？为什么不干脆窝呢？

I'm not sure I understand the problem. Do you know the foreach loop? Why not simply nest it?

foreach ($array as $i => $values) {
    print "$i {\n";
    foreach ($values as $key => $value) {
        print "    $key => $value\n";
    }
    print "}\n";
}
