php - 设置 php 变量以查找当前页面

Question

$pages = array('Text1.php', 'Text2.php', 'Text3.php');

// $currentpage depends the page you're on

$currentId = array_search($currentpage, $pages);

我有通过 an 访问的 php 脚本，include(Text4.php)并且include(Text4.php)存储在数组中的所有三个 php 脚本中。现在我要做的是设置£currentpage它，使其等于用户当前所在的页面，并匹配一个值，$pages该值应该是当前页面的文件名。

我的问题是，在上面的代码中，应该如何编写 $currentId 变量来执行它应该实现的功能？

Answer 1

仅文件名：

$currentPage = basename(__FILE__);

__

目录名+文件名：

$currentPage = __FILE__;

__

仅目录：

$currentPage = __DIR__;

Answer 2

//如果你想要一个路径

$currentpage = $_SERVER['PHP_SELF'];

//如果你只想要实际的文件名（字面意思是“Test.php”）

$posofslash = strrpos($_SERVER['PHP_SELF'],'/');
$currentpage = substr($_SERVER['PHP_SELF'],$posofslash);

这是我用于浏览器游戏的一段代码。措辞略有改变，但代码本身运行良好。任何 php 代码都可以放在“if”语句中，我使用了“print”。

    ///---Various Navigation & Functions Depending on Current Page---///

$findpage = strrpos($_SERVER['PHP_SELF'],'/');  
$currentpage = substr($_SERVER['PHP_SELF'],$findpage);
if ($currentpage == '/home.php'){
 print "This message is displayed when the client is on the 'home' page.";
 print "If you so chose, you can put the entire 'home' page code in here.";
 print "While keeping this the only code being executed.";}
if ($currentpage == '/features.php'){
 print "This message is displayed when the client is on the 'features' page.";
 print "If you so chose, you can put the entire 'features' page code in here.";
 print "While keeping this the only code being executed.";}
if ($currentpage == '/menu.php'){
 print "This message is displayed when the client is on the 'menu' page.";
 print "If you so chose, you can put the entire 'menu' page code in here.";
 print "While keeping this the only code being executed.";}
if ($currentpage == '/store.php'){
 print "This message is displayed when the client is on the 'store' page.";
 print "If you so choose, you can put the entire 'store' page code in here.";
 print "While keeping this the only code being executed.";}
