php路由转发

.
function get5() {
    $uri = $_SERVER["REQUEST_URI"];
    $uri = parse_url($uri, PHP_URL_PATH);
    $uri = ltrim($uri, "/");
    $uri = $uri ? explode("/", $uri) : ["index"];

    if (count($uri) < 2) {
        $uri[] = 1;
    }

    return $uri;
}

$tmp = get5();
$_GET[$tmp[0]] = $tmp[1];

这段代码处理了请求的 URI，将其分解为数组，并根据条件把地址转为get参数，比如：域名/ps/500,转为$_GET["ps"]=500;
