读取URL最后部分的更好方法

Question

此脚本应该检测完整路径中的最后一部分，如果是stackoverflow输出ok

$current_url = $_SERVER['REQUEST_URI'];

$current_url_arr = explode('/',$current_url);
$count = count($current_url_arr);

if($current_url_arr[$count-2] == 'stackoverflow'){
    echo 'ok';
}
else {
    echo 'not ok';
}

示例1：www.myserver.ext/something/else/stackoverflow/输出：ok

示例2：www.myserver.ext/something/else/stackoverflow输出：not ok

示例3：www.myserver.ext/something/else/stackoverflow/foo输出：not ok

我希望你能理解这个想法。这个脚本运行良好，但我想知道是否有更好、更优雅的方式来读取URL的最后部分？

Answer 1

是!有$_SERVER['PATH_INFO']

if(isset($_SERVER['PATH_INFO'])) {
    $info = explode('/', trim($_SERVER['PATH_INFO'], '/'));

    if($info[count($info) - 1] === 'stackoverflow') {
        echo 'ok';
    } else {
        echo 'not ok';
    }
}

Answer 2

if (preg_match("#stackoverflow/$#", $_SERVER['REQUEST_URI'])) {

    echo 'ok';
}

Answer 3

我认为这是最好的方法：

<?php

    $url = "www.myserver.ext/something/else/stackoverflow/";

    $fullpath = parse_url($url, PHP_URL_PATH);
    $paths = explode("/", $fullpath);
    $path = $paths[sizeof($paths)-1];

    if ($path === "stackoverflow") {
        # Condition satisfied
    }

?>
