PHP的问题包括全局路径 [英] Issue with PHP include with global path
问题描述
我一直面临着PHP包含的问题。基于来自互联网的读数,我一直在使用相对路径来获得灵活性。
I have been facing an issue with the PHP includes. Based on the readings from internet, I have been using relative path to have the flexibility around.
只要我直接在每个文件中引用路径,就像
As long as I refer to a path directly in each file, like
require_once '../includes/connection.php'; // it works fine.
当我使用全局常量引用此路径时,问题就开始了
The issue starts when I refer to this path with a global constant
require_once getDocumentRoot() . '/includes/connection.php',
因为它显示以下错误。
as it says the below error.
Warning: require_once(/phpPractices/myApp/includes/connection.php): failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/phpPractices/myApp/dir1/list.php on line 19".
我一直在阅读SO中的这么多主题,并遵循以下建议:
I had been reading so many threads in SO and following the advices like
- 使用基本导演定义一个常量为DOCUMENT_ROOT文件。(就像它在SO中所说的那样 - > https://stackoverflow.com/a/22912261/1001242)
- 还尝试了各种选项,如 DIR ,基于(文件)等,
- 通过set_include_path()方法将我的应用程序目录(/ phpPractices / myApp)添加到include_path(如 PHP,如何设置包含路径和 http://php.net/manual/en/function.set-include-path.php )
- Define a constant as DOCUMENT_ROOT with the base director of the file. (Like the one what it says here in SO -> https://stackoverflow.com/a/22912261/1001242)
- Also attempted with various options like DIR, basedir(FILE) etc.,
- Added my application directory (/phpPractices/myApp) to the include_path via set_include_path() method (as mentioned in PHP, How to set include path and http://php.net/manual/en/function.set-include-path.php)
我的函数getDocumentRoot()定义如下。
My function getDocumentRoot() is defined as follows.
function getDocumentRoot()
{
$loc_pos_2 = strpos($_SERVER['REQUEST_URI'], "/", 1);
$baseDir = substr($_SERVER['REQUEST_URI'], 0, $loc_pos_2);
$baseDir = $baseDir . "/myApp";
return $baseDir;
}
注意: 我可以看到该文件实际存在。但是,file_exists()方法返回false,我不明白为什么。可能它可能引起关注?
Note: I could see that the file exists physically. However, file_exists() method returns false, which I don't understand why. Possibly it could have been a cause of concern?
仅供参考,我的目录结构如下。
FYI, my directory structure is as below.
htdocs
phpPractices
myApp --> Web App Root
includes
connection.php
inc
header.php
footer.php
global.php -- contains getDocumentRoot() method and included in header.php
index.php
dir1 --> my module specific dir
list.php --> which needs 'connection.php'
我的list.php包含以下
My list.php contains the below
<?php
include_once '../inc/header.php'; // it works fine as I do relative to the path
//require_once '../includes/connection.php'; //works fine
require_once getDocumentRoot() . '/includes/connection.php'; // FAILS! :(
?>
但没有任何帮助!任何建议都可以获得我们非常感谢摆脱这个问题。
But nothing helps! Any suggestion to get rid of this issue will be much appreciated.
提前致谢!
解决方案
感谢所有回复过的人。我得到了一个新的解决方法,有点帮助我:)
Thanks to all the people whoever had replied. I got a new workaround that kinda helps me :)
1. For all the menu items with links:
I use my getDocumentRoot() method which provides me -
'/phpPractices/myApp/' --> which is relative to my Web App.
2. For all the include, require functions :
I defined a different constant as below & as per this link:
https://stackoverflow.com/a/1488293/1001242
define('APP_BASE_PATH', $_SERVER['DOCUMENT_ROOT'] . '/myApp');
which returns me the complete absolute path which works fine for file inclusion.
我一直在干涉这两者。对于文件包含,getDocumentRoot()的/ phpPractices / myApp输出失败,因为它试图在根目录(/ phpPractices /)中找到名为phpPractices的目录,这是根本原因。因此,我将这些分成两部分,现在工作正常。
I had been meddling with these both. For the file inclusion, the getDocumentRoot()'s output of "/phpPractices/myApp" was failing as it was attempting to locate a directory named 'phpPractices' in the root ("/phpPractices/"), which was the root cause. Hence, I had split these into two and now works fine.
谢谢大家。非常感激。
Thanks everyone. Much appreciated.
推荐答案
更新你的getDocumentRoot()函数以返回绝对路径
Update your getDocumentRoot() function to return absolute path
function getDocumentRoot()
{
return dirname(__FILE__);
}
或使用 dirname(__ FILE __)
