[php]如何用逗号将数组值转换为一个数组值？

Question

是否可以在一个值中连接关键类型country 例如[genres] =＆gt; value1，value2，value3 因为存在一个问题，即前一个循环的值被添加到下一个循环

Change:  
require_once __DIR__.'../public/index.php';  
To:  
require_once __DIR__.'../public_html/new_project/index.php';  
Save and close. 

这是我的代码：

上一个循环的值将添加到下一个

离。

1. A
2. 乙
3. C
4. d

结果：

A = A

A + B = B

A + B + C = C

A + B + C + D = D

输出[genres]

foreach( $urll as $urle){

$results = My_Parser::getMovie($urle);

        foreach($results as $itemz => $valuez) {
        if($itemz=='genres'){
        foreach($valuez as $val) {
            $genr[] = $val['value'];
        }}
        }

        $genre = implode(', ', $genr);

        echo '<tr><th>'.$genre.'</th><th>Importuj</th></tr>'; 

}

Answer 1

您的$genr会不断被追加。在进入嵌套循环之前重置它：

foreach( $urll as $urle){
    ...
    $genr = array(); // Add this!
    foreach($results as $itemz => $valuez) {
       ...
    }
    ...
    $genre = implode(', ', $genr); // Now you're good.
    ...
}

Answer 2

您需要在foreach($valuez as $val)

的foreach之前初始化数组

 foreach( $urll as $urle){

    $results = My_Parser::getMovie($urle);

        foreach($results as $itemz => $valuez) {
            if($itemz=='genres'){
             $genr=array();  //initialization
            foreach($valuez as $val) {
                $genr[] = $val['value'];
                }
               $genre = implode(', ', $genr); // use the variable -- As per as your requirement.
               echo '<tr><th>'.$genre.'</th><th>Importuj</th></tr>'; 
             }

            }

    }
