在Perl文件中包含PHP配置值

我在CodeIgniter（v2.x）中有一个PHP应用程序，它有一个配置文件，它的值采用相当标准的PHP格式，例如：

$config['key1'] = 'value1';
$config['key2'] = 'value2';

我正在编写一个Perl程序，每晚运行一次，将信息解析到数据库中供PHP使用/显示，我可以让Perl程序从PHP读取配置值吗

我尝试了

PHP：：Include module

，但是生成的Perl值似乎是空的（使用DEBUG）模块。我还尝试了

Config:：ini文件模块

，但我的源代码未配置为

ini

文件

谢谢

是的，您可以将配置数组转换为与语言无关的格式，如json：

$json = json_encode($this->config->config);

---

现在您已经有了json格式的配置数组，您可以将其保存到一个文件中，或者直接从程序中通过ajax请求检索它，或者对它执行任何操作。

如果它是这样一个简单的配置文件

    <?php

/**
*
*  service: /www/vhosts/x456/docs/config.php
*  program: community one
*  version: 1.01, 01/01/2009 01:01:01
*
**/

$config                  = array ();

$config['system_admin']  = 1;

$config['system_name']   = 'Community One';

$config['session_name']  = 'community';

$config['system_email']  = '@gmail.com';

$config['system_allow']  = '127.0.0.1';

$config['storage_type']  = 'file';

$config['host_name']     = '';

$config['service_path']  = '/';

$config['system_root']   = 'c:/services/www/vhosts/x456/';

$config['document_root'] = 'c:/services/www/vhosts/x456/docs/';

$config['database_name'] = 'community';

$config['database_host'] = 'localhost';

$config['database_user'] = 'admin';

$config['database_pass'] = '';

$config['database_type'] = 'mysqli';

$config['database_port'] = '3306';

$config['database_salt'] = '*^&$_';

$config['min_timeout']   = 180;

$config['max_timeout']   = 31557600;

$config['ssl_only']      = FALSE;

?>

如果需要使用多种语言，请考虑将配置更改为更独立于语言的格式。XML、JSON、YAML、INI等。。或者编写一个适配器PHP程序，Perl可以调用该程序，它读取配置并以Perl程序可以使用的方式显示配置。或者，如果配置足够简单，试着用Perl编写自己的解析器。如果格式真的“相当标准”，那么一个简单的正则表达式就可以对这些设置进行grep处理。@stickybit没有更多的内容可以添加到您的解释中，我在回答中将整个配置数组转换为json格式。@mario-XML、json和YAML都是“相当标准”的配置格式不能被正则表达式解析，更不用说简单的正则表达式了。
