Example analysis of config.php usages of codeigniter configuration _php Example

The config.php usage of codeigniter configuration is analyzed in this paper. Share to everyone for your reference, specific as follows:

Configuration Instructions

$config [' Language ']: Specifies the project language pack. When you need to be aware of the CodeIgniter class library error prompt language pack is located in the/system/language/english/directory, when you configure non-Chinese, if you need to use these class libraries, you need to copy the language pack into the specified directory, Otherwise, there will be a load error.

$config [' CharSet ']: Set the system to use the encoding, in some need to specify the encoding function will be used, the system, the database unified coding can be.

$config [' Enable_hooks ']: Hook switch control, set to True to allow the use of hooks, otherwise not allowed.

$config [' Subclass_prefix ']: Sets the custom class library, the function prefix, defaults to my_, such as when you need to rewrite the Lang method in the language helper, just create the My_ in the helper directory language_herper.php, and implement the Lang function to implement "overload." Here My_ is the value defined in Subclass_prefix.

$config [' Permitted_uri_chars ']: Sets the allowed characters in the URL.

$config [' Log_threshold ']: Set the logging level, 0 to turn off logging, and 4 to record all information, typically set to 1. After setting, you need to confirm that the logs directory has write permissions.

$config [' proxy_ips ']: When the server uses the agent, remoter_addr to get the IP of the proxy server, the need from Http_x_forwarded_for, HTTP_CLIENT_IP, Http_x_client_ip, HTTP_X_CLUSTER_CLIENT_IP, or other set of values. Set here is the proxy server IP, comma-delimited.

$config [' Encryption_key ']: Encrypt the value, and you must set it if you want to use the sesion from the CI band. The self-contained session of CI is stored in the cookie and is encrypted for security purposes.

Configure read

CI initialization begins by loading the config.php file with the Get_config function, as well as providing config_item to obtain the value of config, such as:

Copy Code code as follows:

echo Config_item (' CharSet ');

CI also provides a configuration class for maintaining configuration files. You can also get and set the value of config in the following way, and the result of calling Get_config after the setting changes, so you can modify the config value before some logic.

Gets the charset value configured in config
echo $this->config->item (' CharSet ');
Reset the value of the CharSet in config
$this->config->set_item (' CharSet ', ' GBK ')
