php - foreach 结果在同一行

Question

我有这段代码:

    foreach ($ck as $k) {
         if (substr ($k, 0, 1) == '_')
         {   // skip keys starting with '_'
             continue;
         }
         $cv = get_post_custom_values($k, $post_id );  //Array

            foreach ($cv as $c) {
                if (empty ($c))
                {   // skip empty value
                    continue;
                }
                $format_c =  $c;

                print_r ('<div style="font-size: 14px;">'.$k .': '. $format_c . ' / </div>');

            }
    }

?>

但是结果是这样的:

something: result /
something: result /
something: result /

我怎样才能更改代码:

something: result / something: result / something: result /

谢谢!

A <div> 是 block 级元素。使用像 <span> 这样的内联元素相反。

    foreach ($ck as $k) {
         if (substr ($k, 0, 1) == '_')
         {   // skip keys starting with '_'
             continue;
         }
         $cv = get_post_custom_values($k, $post_id );  //Array

            foreach ($cv as $c) {
                if (empty ($c))
                {   // skip empty value
                    continue;
                }
                $format_c =  $c;

                echo "<span style='font-size: 14px;'>$k: $format_c / </span><br/>";

            }
    }

?>

另外，我不认为print_r()做你认为它做的事。 echo 或 print 用于输出文本。
