遍历数组和presenting结果数组 [英] Iterating over array of arrays and presenting the results

问题描述

我如何访问$值的内容[$ i]这是一个数组。没有运气下面的表格使用的foreach。

我们的想法是通过$ contentArray循环并显示一个项目从每次迭代每个子阵列

  $ addsContent = $ Adds-＆GT; selectAdds（10）;
$ sharedArticlesContent = $ SharedContent-＆GT; getSharedContent（$ topic_selected，$ filter_selected）;
$ blogPostsContent = $ BlogPosts-＆GT; getRecentBlogPostsByTopic（业务）;$ contentArray =阵列（    $ sharedArticlesContent，
    $ addsContent，
    $ blogPostsContent
）;
的foreach（$ contentArray为$值）
    {
        如果（计数（$值）＆GT; $最大长度）
        {
            $最大长度=计数（$值）;
        }
    }为（$ I = 0; $ I＆LT; $最大长度; $ I ++）
{
    的foreach（$ contentArray为$值）
    {
        如果（使用isset（$价值[$ i]））
        {
            如果（$价值== $ sharedArticlesContent）{
                $数据= $价值[$ i];
                的foreach（$ sharedArticlesContent为$数据）{                    $ POST_ID = $数据['身份证'];
                    $ uploaded_by = $数据['uploaded_by'];
                    $文字= $数据['文本'];
                    $图像= $数据['形象'];                    需要'template1.php';              }
            } ELSEIF（$价值== $ addsContent）{
                //则Template2
            }其他{
               // template3
            }        }    }
}
 

解决方案

您不需要的foreach 。 $数据是一个关联数组，你不通过它需要循环。

 如果（$价值== $ sharedArticlesContent）{
            $数据= $价值[$ i];
            $ POST_ID = $数据['身份证'];
            $ uploaded_by = $数据['uploaded_by'];
            $文字= $数据['文本'];
            $图像= $数据['形象'];            需要'template1.php';
          }
 

How can I access the contents of $value[$i] which is an array. No luck using foreach in the form below.

The idea is to loop through $contentArray and display one item from each sub-array on every iteration.

$addsContent = $Adds->selectAdds(10);
$sharedArticlesContent = $SharedContent->getSharedContent($topic_selected, $filter_selected);
$blogPostsContent = $BlogPosts->getRecentBlogPostsByTopic("business");

$contentArray = array(

    $sharedArticlesContent,
    $addsContent ,
    $blogPostsContent
);


foreach($contentArray as $value)
    {
        if(count($value)>$maxLength)
        {
            $maxLength = count($value);
        }
    }

for($i=0; $i<$maxLength; $i++)
{
    foreach($contentArray as $value)
    {
        if(isset($value[$i]))
        {
            if($value==$sharedArticlesContent){
                $data = $value[$i];
                foreach($sharedArticlesContent as $data){

                    $post_id = $data['id'];
                    $uploaded_by = $data['uploaded_by'];
                    $text = $data['text'];
                    $image = $data['image'];

                    require 'template1.php';

              }
            }elseif($value==$addsContent){
                //template2
            }else{
               //template3
            }

        }

    }
}

解决方案

You don't need the foreach. $data is an associative array, you don't need to loop through it.

        if($value==$sharedArticlesContent){
            $data = $value[$i];
            $post_id = $data['id'];
            $uploaded_by = $data['uploaded_by'];
            $text = $data['text'];
            $image = $data['image'];

            require 'template1.php';
          }
