我想將多級數組轉換爲表。但是，我的代碼不輸出我想要的。它顯示了最後一個孩子，但沒有顯示其他孩子和孫子。多級數組到表

我感謝您的幫助。

DB表

該解決方案涉及遞歸。如果您對該術語不熟悉或難以理解，請參閱此IBM標題爲「Mastering recursive programming」的條目以熟悉您自己。看起來好像你只打算有三個級別的導航。據說，這段代碼只處理這三個級別的父類/子級/孫級。您可以通過向$depthClassMapping添加新的陣列條目來輕鬆添加更多內容。

/** 
* @param array $level The current navigation level array 
* @param string $output The output to be added to 
* @param int $depth The current depth of the tree to determine classname 
*/ 
function generateRowsByLevel($level, &$output, $depth = 0) { 

    $depthClassMapping = array(0 => 'parent', 1 => 'child', 2 => 'grandchild'); 

    foreach ($level as $row) { 
     $output .= "<tr class=\"" . $depthClassMapping[$depth] . "\" valign='top'>\n"; 
     $output .= "<td>". $row['id']."</td>\n"; 
     $output .= '<td><a href="'. site_url(). '/admin/menus/submenus/' . $row['id'] . '">' . $row['name']."</a></td>\n"; 
     $output .= "<td align='center'>". $row['status']."</td>\n"; 
     $output .= "<td align='center'>". $row['parentid']."</td>\n"; 
     $output .= "<td align='center'>"; 
     $output .= anchor('admin/menus/editMenu/'. $row['id'],'edit'); 
     $output .= " | "; 
     $output .= anchor('admin/menus/deleteMenu/'. $row['id'],'delete', array('class' => 'delete_link')); 
     $output .= "</td>\n"; 
     $output .= "</tr>\n"; 

     // if the row has any children, parse those to ensure we have a properly 
     // displayed nested table 
     if (!empty($row['children'])) { 
      generateRowsByLevel($row['children'], $output, $depth + 1); 
     } 
    } 
} 

//================== 
// RUN THE GENERATOR 
//================== 
if (count($navlist)){ 

    // begin table 
    $output = "<table border='1' cellspacing='0' cellpadding='3' width='800'>\n"; 
    $output .= "<thead>\n<tr valign='top'>\n"; 
    $output .= "<th>ID</th>\n<th>Name</th><th>Status</th><th>parentid</th><th>Actions</th>\n"; 
    $output .= "</tr>\n</thead>\n<tbody>\n"; 

    // generate all table rows 
    generateRowsByLevel($navlist, $output); 

    // close up the table 
    $output .= "</tbody>\n</table>"; 

    // display table 
    echo $output; 
}

我將+ =改爲。=和$ depthClasMapping [$ depth]改爲$ depthClassMapping [$ depth]。那麼它的工作。謝謝。 – shin 2009-12-11 16:09:13

今天早上我一定在想'javascript +'' – 2009-12-11 16:12:39

你需要實現一個遞歸函數或使用像函數array_map有一個回調函數來處理多陣列時適當發回數據，您可以在php.net網站上看到有關該功能的更多信息。
