我无法弄清楚如何从这个数组中获取我需要的值:::我需要的3辆车的值是。
我试图通过PHP array documentation来解决这个问题但没有取得多大成功。

答案 0 :(得分:1)
试试这个:
如果此数组位于名为$array
1 - $array['query']['result']['div'][0]['a']['href']
2 - $array['query']['result']['div'][1]['p']
3 - $array['query']['result']['span'][0]['class']
要调试并找到所需的值,请尝试这样做,
var_dump($array['query']);
然后
var_dump($array['query']['result']);
...等

看起来你能够从评论和其他答案中找到答案。但是,我应该澄清一下,我对这个问题的评论有些误导,所以你可以忽视它们。我实际上假设class
引用了PHP对象,实际上class
只是一个字符串的键(该数组看起来像一些解析的HTML / XML)。当您在评论中发布了var_dump()
数组时,我意识到了这一点。
问题是阵列结构相当复杂,所有嵌套都在进行,因此可能很难看出它是什么。一般来说,我同意另一个答案;使用var_dump()
进行调试是一种很好的检查方法。这是我对答案的看法。
假设您的数组变量为$array
:
1
$array['query']['results']['div'][0]['span']['a']['href']
$array['query']['results']['div'][0]['span']['a']['img']['src']
2
$array['query']['results']['div'][1]['span']['p']
3
$array['query']['results']['span'][0]['content']
4
$array['query']['results']['span'][1]['content']
