PHP项目的文件结构 [英] File Structure for a PHP Project
问题描述
我的文件结构：
/holiday/admin/list.php
/ holiday / includes / functions。 php＃常用函数
/holiday/index.php
＃/是文档根目录
＃/ holiday /是一个独立的子目录
＃还有其他自包含的子目录，例如/ promotion /，/ international /
在 functions.php 我有一个通用的函数来生成HTML的< head> 部分;另外，还有一个从文档根目录返回绝对路径的函数。 注意我试图计算 / holiday / includes / 。
< ;?函数get_path（）{
//技术上，这返回dirname（__ FILE__） - $ _SERVER ['DOCUMENT_ROOT']
返回str_replace（$ _ SERVER ['DOCUMENT_ROOT']，，dirname（__ FILE__）） ;
}？>
<？函数open_page（$ head =，$ body_id =）{？>
<！DOCTYPE HTML>
< html>
< head>
< link type =text / css =stylesheethref =< ;? echo get_path（）。/../css/savvyextras.css;？> />
< script type =text / javascriptsrc =< ;? echo get_path（）。/../scripts/modernizr.js;？>>< / script>
...
<？ }？>
functions.php
//从list.php
require_once（'../ includes / functions.php'）;
open_page（...）;
//从index.php
require_once（'./ includes / functions.php'）;
open_page（...）;
我觉得在这里必须有更直接的方法来完成同样的事情。对于 get_path（）的任何内置PHP函数？也许我应该以不同的方式处理我的问题？
有些人建议使用框架（这是一件好事）。但是，为了帮助我（和其他人）理解整个包含文件的事情，还有其他的非框架解释？
- 在非根目录中部署的绝对路径 文件相对路径>包含文件的相对路径
经过更多的尝试，并收集其他投入，我发现使用常量将做的伎俩：
$ p $ ＃functions.php
define（'PREFIX'，'/ holiday'）;
<？函数open_page（$ head =，$ body_id =）{？>
<！DOCTYPE HTML>
< html>
< head>
< link type =text / css =stylesheethref =<？php echo PREFIX;？> /css/savvyextras.css; ？>/>
< script type =text / javascriptsrc =<？php echo PREFIX; ？> /scripts/modernizr.js;？>>< / script>
...
<？ }？>
所以，如果您需要移动 / holiday / 到不同的子目录，例如 / vacation / ，你只需要改变一个常量即 PREFIX 。
My file structure:
/holiday/admin/list.php
/holiday/includes/functions.php # common functions
/holiday/index.php
# / is the document root
# /holiday/ is a "self-contained" sub-directory
# There are other "self-contained" sub-directories e.g. /promotion/, /international/
In functions.php I have a common function to generate the <head> part of an HTML; also, a function to return an absolute path from the document root. Note my attempt to calculate /holiday/includes/.
<? function get_path() {
// Technically, this returns dirname(__FILE__) - $_SERVER['DOCUMENT_ROOT']
return str_replace($_SERVER['DOCUMENT_ROOT'], "", dirname(__FILE__));
} ?>
<? function open_page($head = "", $body_id = "") { ?>
<!DOCTYPE HTML>
<html>
<head>
<link type="text/css" rel="stylesheet" href="<? echo get_path() . "/../css/savvyextras.css"; ?>" />
<script type="text/javascript" src="<? echo get_path() . "/../scripts/modernizr.js"; ?>"></script>
...
<? } ?>
functions.php is included this way:
// From list.php
require_once('../includes/functions.php');
open_page(...);
// From index.php
require_once('./includes/functions.php');
open_page(...);
I feel like there must be a more straightforward approach to accomplish the same thing here. Any built-in PHP function for my get_path()? Maybe I should approach my problem differently?
Note: Some folks suggested using a framework (which is a good thing). But, to help me (and others) understand this whole include-file thing, other non-framework explanations?

After experimenting more with this and gathering other inputs, I find using constant will do the trick:
# functions.php
define('PREFIX', '/holiday');
<? function open_page($head = "", $body_id = "") { ?>
<!DOCTYPE HTML>
<html>
<head>
<link type="text/css" rel="stylesheet" href="<?php echo PREFIX; ?>/css/savvyextras.css"; ?>" />
<script type="text/javascript" src="<?php echo PREFIX; ?>/scripts/modernizr.js"; ?>"></script>
...
<? } ?>
So, if you need to move /holiday/ to a different sub-directory e.g. /vacation/, you'd simply need to change one constant i.e. PREFIX.
