爲什麼我的PHP case語句不起作用？

Question

下面是我的代碼。相當直線前進。只有默認條件正在執行。註釋掉其他語句是否有效。我正試圖用開關統計來代替。

$currCat = (int)$_GET['cPath']; 

switch ($currCat) { 
case 4: 
$tpl_page_body = '/tpl_product_info_display_threads.php'; 
case 1: 
$tpl_page_body = '/tpl_product_info_display_canvas.php';  
case 3: 
$tpl_page_body = '/tpl_product_info_display_belts.php';  
case 85: 
$tpl_page_body = '/tpl_product_info_display_books.php'; 
case 75: 
$tpl_page_body = '/tpl_product_info_display_beltsDEV.php'; 
default: 
$tpl_page_body = '/tpl_product_info_display.php'; 
} 
/* 
if($currCat == 4) { 
$tpl_page_body = '/tpl_product_info_display_threads.php'; 
} elseif ($currCat == 1) { 
$tpl_page_body = '/tpl_product_info_display_canvas.php'; 
etc. etc. */ 

非常感謝你提前

你需要把break報表在所有情況下，除非之間你希望他們級聯（我假設你不這樣做）

switch ($currCat) { 
    case 4 : 
     $tpl_page_body = '/tpl_product_info_display_threads.php'; 
     break; 
    case 1 : 
     $tpl_page_body = '/tpl_product_info_display_canvas.php'; 
     break; 
    // and so on 
}
