错误500当试图从数组中生成PHP开关

Question

我想切换出目录中的文件名，所以我不必每次添加新的开关时，我添加新的内容...例如，如果文件名称是Domain_Hosting.php，我想使交换机/ url？op = Domain_hosting（减去.php）。下面的脚本作品最多foreach语句，我究竟做错了，请帮忙

<? 
require_once("C:/www/db.php"); 
stripslashes($_GET); 
str_replace("%", '', $_GET); 
$op = $_GET['op']; 
$op = stripslashes($op); 
$op = str_replace("/", '', $op); 
$op = str_replace("%", '', $op); 
$op = str_replace(".", '', $op); 
$op = str_replace("+", '', $op); 
$dir = './includes/content/'; 

$files1 = scandir($dir, 1); 

$files1 = array_map(function($e){ 
return pathinfo($e, PATHINFO_FILENAME); 
}, $files1); 

switch($op) { 

default: 
require_once("includes/content/home.php"); 
break; 

    foreach ($files1 as &$file) { 
    case "$file": 
    require_once("includes/content/$file.php") 
    } 
} 
?> 

Answer 1

尝试这种方法

<? 
require_once("C:/www/db.php"); 
stripslashes($_GET); 
str_replace("%", '', $_GET); 
$op = $_GET['op']; 
$op = stripslashes($op); 
$op = str_replace("/", '', $op); 
$op = str_replace("%", '', $op); 
$op = str_replace(".", '', $op); 
$op = str_replace("+", '', $op); 
$dir = './includes/content/'; 

$files1 = scandir($dir, 1); 

$files1 = array_map(function($e){ 
return pathinfo($e, PATHINFO_FILENAME); 
}, $files1); 


if(count(files1)>0){ 
foreach ($files1 as &$file) { 
    require_once("includes/content/$file.php") 
    } 
} 
else 
require_once("includes/content/home.php");

这缝工作

require_once("C:/www/db.php"); 
stripslashes($_GET); 
str_replace("%", '', $_GET); 
$op = $_GET['op']; 
$op = stripslashes($op); 
$op = str_replace("/", '', $op); 
$op = str_replace("%", '', $op); 
$op = str_replace(".", '', $op); 
$op = str_replace("+", '', $op); 
$dir = './includes/content/'; 

$files1 = scandir($dir, 1); 

$files1 = array_map(function($e){ 
return pathinfo($e, PATHINFO_FILENAME); 
}, $files1); 

if (!isset($op)) { 
require_once("includes/content/home.php"); 
home(); 
} 

if(isset($op)) { 
    foreach ($files1 as &$file) { 
    if($op == $file){ 
    require_once("includes/content/$file.php"); 
    } 
    } 
}
