编辑PHP文件以通过PHP进行配置 [英] Editing PHP files for configuration via PHP

问题描述

首先，我认为由于使用此方法的各种流行软件（例如SMF），这不是不好的做法。

First of all, I am assuming this is NOT bad practice due to various popular software using this method, such as SMF.

无论如何，所以我目前有代码：

Anyway, so I currently have this code:

<?php
// main visual config
$cfg['lang']    = 'en';

// paths
$path['admin']  = 'index.php?p=admin';
$path['admin2'] = 'zvfpcms/admin';
$path['root']   = 'zvfpcms';
$path['images'] = 'zvfpcms/img';
$path['css']    = 'zvfpcms/css';
$path['js']     = 'zvfpcms/js';
$path['pages']  = 'zvfpcms/pg';
?>

问题是，我希望通过接口直接编辑$ cfg变量。

The thing is, I want the $cfg variable(s) to be edited directly via an interface.

这将如何实现？我认为替换字符串不是一个好主意，尤其是当我将来创建的$ cfg变量存在很多（甚至是无限）的可能性时。

How would this be achieved? I cannot think replacing strings would be a good idea especially when there are a very large number of possibilities (or even infinite) for future $cfg variables I create.

或者，我将不得不选择其他方法吗？

Or, will I have to settle for a different method...

答案表示赞赏！

推荐答案

Pear Config 可让您轻松地从不同来源读取和写入配置，包括PHP文件/数组。不过，您可能需要将 $ cfg 移到其自己的文件中并包括它，以便其他变量等不受影响。

Pear Config will let you read and write configuration easily to/from different sources, including a PHP file/array. You would probably need to move $cfg into its own file though and include it so that other variables etc. are unaffected.

您也可以使用 var_export（） 然后覆盖文件，再次可能需要将变量移到其自己的文件中。我认为这会写出比Pear类更混乱，可读性更差的PHP。

You could also do it yourself using var_export() and then writing over the file, again you would probably need to move the variable into its own file. I think that this would write messier/less readable PHP than the Pear class.
