CI中的配置文件默认都在application/config/路径下,当然也可以在你的自定义路径下,其中config.php是自动加载的,如果需要程序初始化的时候自动加载你需要的配置文件,那么在autoload.php中,在$autoload[‘config’] = array();中加入你需要的文件名即可。
在自定义配置文件中需要注意的一点就是,你所有的配置数据都需要放到全局的配置变量$config中,比如在application/config/路径下,新建了一个配置文件customized.php.内容如下:
$customize = array(
'customize1' => 1,
'customize2' => 2,
'customize3' => 3,
'customize4' => 4,
'customize5' => 5,
'customize6' => 6,
'customize7' => 7,
);
假定手动加载该文件$this->config->load(‘customized’);会发现有如下报错
Your application/config/sns.php file does not appear to contain a valid configuration array.
提示这个配置文件没有包含一个合法的配置数组,那么合法的配置数组是怎样的呢,通过看核心配置类源码system/core/Config.php中的load方法
/**
* Load Config File
*
* @access public
* @param string the config file name
* @param boolean if configuration values should be loaded into their own section
* @param boolean true if errors should just return false, false if an error message should be displayed
* @return boolean if the file was loaded correctly
*/
function load($file = '', $use_sections = FALSE, $fail_gracefully = FALSE)
{
$file = ($file == '') ? 'config' : str_replace('.php', '', $file);
$found = FALSE;
$loaded = FALSE;
$check_locations = defined('ENVIRONMENT')
? array(ENVIRONMENT.'/'.$file, $file)
: array($file);
foreach ($this->_config_paths as $path)
{
foreach ($check_locations as $location)
{
$file_path = $path.'config/'.$location.'.php';
if (in_array($file_path, $this->is_loaded, TRUE))
{
$loaded = TRUE;
continue 2;
}
if (file_exists($file_path))
{
$found = TRUE;
break;
}
}
if ($found === FALSE)
{
continue;
}
include($file_path);
if ( ! isset($config) OR ! is_array($config))
{
if ($fail_gracefully === TRUE)
{
return FALSE;
}
show_error('Your '.$file_path.' file does not appear to contain a valid configuration array.');
}
if ($use_sections === TRUE)
{
if (isset($this->config[$file]))
{
$this->config[$file] = array_merge($this->config[$file], $config);
}
else
{
$this->config[$file] = $config;
}
}
else
{
$this->config = array_merge($this->config, $config);
}
$this->is_loaded[] = $file_path;
unset($config);
$loaded = TRUE;
log_message('debug', 'Config file loaded: '.$file_path);
break;
}
if ($loaded === FALSE)
{
if ($fail_gracefully === TRUE)
{
return FALSE;
}
show_error('The configuration file '.$file.'.php does not exist.');
}
return TRUE;
}
加载自定义配置的这个方法,非要在自定义配置文件中找到$config这个变量才罢休,否则就是不合法的。所以,只需要在我们原来的自定义配置文件加上一行就ok了,如下
$customize = array(
'customize1' => 1,
'customize2' => 2,
'customize3' => 3,
'customize4' => 4,
'customize5' => 5,
'customize6' => 6,
'customize7' => 7,
);
$config['customize'] = $customize;
如此写法,不免觉得有些僵硬。。。
