php – 获取基本路径/ URL

导读：我试图通过函数获取文档的基本路径,因为我不想找到像../folder1/folder2/mypage.php或../../../folder1/folder2/somepage这样的路径. PHP. 所以我试过…… function getBaseUrl() {// output: /myproject/index.php$currentPath = $_SERVER['PHP_SELF'];// o

我试图通过函数获取文档的基本路径,因为我不想找到像../folder1/folder2/mypage.php或../../../folder1/folder2/somepage这样的路径. PHP.

所以我试过……

function getBaseUrl() {
// output: /myproject/index.php
$currentPath = $_SERVER['PHP_SELF'];

// output: Array ( [dirname] => /myproject [basename] => index.php [extension] => php [filename] => index )
$pathInfo = pathinfo($currentPath);

// output: localhost
$hostName = $_SERVER['HTTP_HOST'];

// output: http://
$protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],5))=='https://'?'https://':'http://';

// return: http://localhost/myproject/
return $protocol.$hostName.$pathInfo['dirname']."/";
}

然后我给写代码……

$base = getBaseUrl();
require_once $base.'_include/db/qry.php';
require_once $base.'_include/db/functions.php';

两个文件qry.php& functions.php在http：// localhost / mysite / _include / db /中

当我运行页面时,错误显示…

Warning: require_once(): http:// wrapper is disabled in the server configuration by allow_url_include=0 in C:xampphtdocsmysite_includeheader.php on line 9

Warning: require_once(http://localhost/mysite/_include/db/qry.php): failed to open stream: no suitable wrapper could be found in C:xampphtdocsmysite_includeheader.php on line 9

Fatal error: require_once(): Failed opening required 'http://localhost/mysite/_include/db/qry.php' (include_path='.;C:xamppphpPEAR') in C:xampphtdocsmysite_includeheader.php on line 9

我尝试通过回显像echo $base这样的getBaseUrl();它显示正确的路径,即http：// localhost / mysite /.

我该怎么办？

解决方法

您应该只使用服务器上的绝对路径而不是url.

您可以使用__DIR__获取基本路径.

例如：

// just example,change to fit your real path.
$base = __DIR__ . '/../';

require_once $base.'_include/db/qry.php';
require_once $base.'_include/db/functions.php';
