打印Array PHP的元素

Question

我有从Array中的Twitter API调用返回的数据数组。我正在重复＆＃34;十大趋势＆＃34;但是不能打印单个元素，例如名称。下面是我尽可能使用的代码：

echo "<pre>";
print_r($string);
echo "</pre>";

结果如下：

Array
(
    [trends] => Array
        (
            [0] => Array
                (
                    [name] => #PagiYlanissa
                    [query] => %23PagiYlanissa
                    [url] => http://twitter.com/search?q=%23PagiYlanissa
                    [promoted_content] => 
                )

            [1] => Array
                (
                    [name] => Torikul SMKN2 SRAGEN
                    [query] => %22Torikul+SMKN2+SRAGEN%22
                    [url] => http://twitter.com/search?q=%22Torikul+SMKN2+SRAGEN%22
                    [promoted_content] => 
                )

            [2] => Array
                (
                    [name] => Wali Supit Tamfan Dan Berani
                    [query] => %22Wali+Supit+Tamfan+Dan+Berani%22
                    [url] => http://twitter.com/search?q=%22Wali+Supit+Tamfan+Dan+Berani%22
                    [promoted_content] => 
                )

            [3] => Array
                (
                    [name] => #SelamatMalamNadyaFatira
                    [query] => %23SelamatMalamNadyaFatira
                    [url] => http://twitter.com/search?q=%23SelamatMalamNadyaFatira
                    [promoted_content] => 
                )

            [4] => Array
                (
                    [name] => #fireproof
                    [query] => %23fireproof
                    [url] => http://twitter.com/search?q=%23fireproof
                    [promoted_content] => 
                )

            [5] => Array
                (
                    [name] => Bersyukur
                    [query] => Bersyukur
                    [url] => http://twitter.com/search?q=Bersyukur
                    [promoted_content] => 
                )

            [6] => Array
                (
                    [name] => Selamat Hari Olahraga Nasional
                    [query] => %22Selamat+Hari+Olahraga+Nasional%22
                    [url] => http://twitter.com/search?q=%22Selamat+Hari+Olahraga+Nasional%22
                    [promoted_content] => 
                )

            [7] => Array
                (
                    [name] => #RIPRise
                    [query] => %23RIPRise
                    [url] => http://twitter.com/search?q=%23RIPRise
                    [promoted_content] => 
                )

            [8] => Array
                (
                    [name] => Tanggal 9
                    [query] => %22Tanggal+9%22
                    [url] => http://twitter.com/search?q=%22Tanggal+9%22
                    [promoted_content] => 
                )

            [9] => Array
                (
                    [name] => #LP3IPastiKerja
                    [query] => %23LP3IPastiKerja
                    [url] => http://twitter.com/search?q=%23LP3IPastiKerja
                    [promoted_content] => 
                )

        )

    [as_of] => 2014-09-08T23:30:17Z
    [created_at] => 2014-09-08T23:25:24Z
    [locations] => Array
        (
            [0] => Array
                (
                    [name] => Indonesia
                    [woeid] => 23424846
                )

        )

)

但是我无法通过顶部的Array访问各个元素。有什么建议吗？

Answer 1

这应该有效：

$trends = $string[0]['trends'];

foreach ($trends as $trend) {
    // Do stuff with $trend['name'], $trend['query'], etc.
}

Answer 2

类似的东西：

foreach ($string[0]['trends'] as $trending)
{
  extract($trending);
  echo $name.'<br>';
}
