thinkphp loading custom external files and configuration files

We know that thinkphp has public function files and configuration files, in the common directory, the default common/function.php is a public function file, conf/config.php is a public profile. OK, so how do you customize other public functions and configuration files? Here we have to talk about two configuration parameters Load_ext_file and Load_ext_config.

1. Load_ext_file configuration is a custom function file, such as I want to create a common.php file in the common directory, then the config.php can be configured load_ext_file=> ' common ', This will automatically load the common.php file.

Common/conf/config.phpreturn Array (load_ext_file=> ' Common ');

Then write a method in the common.php, such as:

function T_dump ($data) {if (!empty ($data)) {echo ' <pre> ';         Var_dump ($data);    Echo ' </pre> '; }}

Call T_dump (Array ()) in the controller, output:

Array (3) {[0]=> int (1) [1]=> int (2) [2]=> int (3)} If another file is created under Common, test.php, define a test function in the test.php file Functio N () {echo ' Test ';} Then the direct call in the controller will be an error: Calls to undefined function home\controller\test () If you add test in config.php, ' load_ext_file ' = ' common, Test ', it executes normally. 2.load_ext_config is used for custom profiles, such as config.php you want to introduce an additional configuration file global.php so you can configure it in config.php:

Load_ext_config=> ' Global ' then you create a global.php file in the Conf directory, write a configuration parameter return array (' mongo_dbname ' = ' idacker ');

Then C calls Echo C (' Mongo_dbname ')

Output: Idacker3. Load principle, in fact, the loading of custom functions and configuration files is attributed to the Load_ext_file function,/** *  load dynamic extension files  *  @var  string  $path   file Paths  *  @return  void */function load_ext_file ($path)  {     //  Load Custom External file     if ($files  = c (' Load_ext_file '))  {          $files       =  explode (', ', $ files);        foreach  ($files  as  $file) {              $file    =  $path. ' common/'. $file. PHP ';             if (Is_file ($file))  include   $file;        }    }       Load Custom dynamic profile     if ($configs  = c (' Load_ext_config '))  {      &Nbsp;  if (is_string ($configs))   $configs  =  explode (', ', $configs);         foreach  ($configs  as  $key + $config) {              $file    = is_file ($config)?  $ config :  $path. ' conf/'. $config. Conf_ext;            if (Is_file ($file))  {                 is_numeric ($ Key)? C (Load_config ($file)): C ($key, Load_config ($file));             }        }    }} The function needs to pass in a $path directory path. For example, if we pass in Common_path, the common.php function and global.php configuration file created in the above two steps will be loaded.
