Php array\u push创建的array运行异常。尝试输出关联数组时，值返回数组的第一个字母或；A「；

我试图使用foreach来输出下面的数组。我通过基于preg\u match if/else的array\u push（）创建了这个数组

Array (
    [0] => Array (
        [date] => 
        [clickurl] => some data
        [url] => some data
        [dispurl] => some Data...
        [title] => Transformers: Revenge of the Fallen : Reviews
        [abstract] => "Transformers: Revenge of the Fallen" is a horrible experience of unbearable length, briefly punctuated by three or four amusing moments.
    )

    [1] => Array (
        [date] => 
        [clickurl] => some data
        [url] => some data
        [dispurl] => some Data...
        [title] => Transformers : Reviews
        [abstract] => After a string of bad-to-mediocre films, director Michael Bay scores with blockbuster battling robots in "Transformers."
    )
)

尝试输出阵列时：

foreach ($reviewArr as $review) {
    echo($review['clickurl']. '<br/><br/>');
}

输出为：

Array ( 
    [date] => 
    [clickurl] => some data 
    [url] => some data
    [dispurl] => some data... 
    [title] => Transformers : Reviews 
    [abstract] => After a string of bad-to-mediocre films, director Michael Bay scores with blockbuster battling robots in "Transformers." 
) 

我不知道为什么会这样。任何帮助都将不胜感激

谢谢

这是我在下面解析的原始数组，将其拆分为两个不同的数组

Array
    (
[bossresponse] => Array
    (
        [responsecode] => 200
        [web] => Array
            (
                [start] => 0
                [count] => 14
                [totalresults] => 14
                [results] => Array
                    (
                        [0] => Array
                            (
                                [date] => 
                                [clickurl] => http://url.com/1
                                [url] => http://url.com/1
                                [dispurl] => http://url.com/1...
                                [title] => Title of Content 1
                                [abstract] => This is the summary, This is the summary,    This is the summary, ...
                            )

                        [1] => Array
                            (
                                [date] => 
                                [clickurl] => http://url.com/2
                                [url] => http://url.com/2
                                [dispurl] => http://url.com/2...
                                [title] => Title of Content 2
                                [abstract] => This is the summary, This is the summary,  This is the summary, ...
                            )
                    )

              )

       )

)

这就是我设置$reviewArr[]的方式

foreach ($results['bossresponse']['web']['results'] as $key => $result) {
                $url = $result['clickurl'];
                $title = $result['title'];
                $abstract = $result['abstract'];
                $resultItem = print_r($results['bossresponse']['web']['results'][$key], true);
                if (preg_match ("/reviews/i", "$url")) {
                    array_push($reviewArr, "$resultItem");
                } else {
                    array_push($resultsArr, "$resultItem");
                }
            }

更新#2-

多亏了@fabio，我才用上面的

$resultItem

设置了一个字符串。如何创建多维数组？如何将其构建为一个数组-我的所有尝试都返回了错误或字符串

 Array
                    (
                        [0] => Array
                            (
                                [date] => 
                                [clickurl] => http://url.com/1
                                [url] => http://url.com/1
                                [dispurl] => http://url.com/1...
                                [title] => Title of Content 1
                                [abstract] => This is the summary, This is the summary,    This is the summary, ...
                            )

                        [1] => Array
                            (
                                [date] => 
                                [clickurl] => http://url.com/2
                                [url] => http://url.com/2

                            )
                    )

我不知道你是如何在你的阵列上推送物品的，但我认为这可以做到：

foreach ($reviewArr as $index=>$review) {
    echo($review['clickurl']. '<br/><br/>');
}

foreach（$revieweras$index=>$review）{
echo（$review['clickurl'].

）；
}

更改：

foreach ($results['bossresponse']['web']['results'] as $key => $result) {
    $url = $result['clickurl'];
    $title = $result['title'];
    $abstract = $result['abstract'];
    $resultItem = print_r($results['bossresponse']['web']['results'][$key], true);
    if (preg_match ("/reviews/i", "$url")) {
        array_push($reviewArr, "$resultItem");
    } else {
        array_push($resultsArr, "$resultItem");
    }
}

为什么要用print\u r的返回值填充数组

// this will return a string
$resultItem = print_r($results['bossresponse']['web']['results'][$key], true);

这就是您行为的原因：您正在打印返回值的第一个字符，它是

$results[…][…]

数组的字符串表示形式

你自己试试看

$foo = "Hello world";
echo $foo[0]; // output H

---

附则

echo（$review.

）

将输出整个字符串，即打印输出。

您可以添加从

var\u dump（$reviewArr）获得的输出吗$reviewArr

的开头从数组中输出单个“A”我更新了原始问题，说明了我如何设置数组……我假设我使用的是print\r？？我做了很多尝试，但都失败了。谢谢@Fabio的回复。我试图使用

$results['bossresponse']['web']['results'][$key]

来构建新的多维数组，但没有成功。你能提供一些关于如何分配给新数组的建议吗？你在foreach中，可以使用

$result

作为整个子数组。您的

preg\u match

需要针对

$result['url']

运行，您应该使用

array\u push（$reviews，$result）

将其分配给另一个数组。您应该阅读一些关于数组的PHP教程；-）

// this will return a string
$resultItem = print_r($results['bossresponse']['web']['results'][$key], true);

$foo = "Hello world";
echo $foo[0]; // output H
