thinkphp implements multi-language functions_PHP tutorial

This article mainly introduces thinkphp to implement multi-language functions (language packs). Friends who need it can refer to it

1. Add the following configuration in config.php of Home (the project name you chose) ​ The code is as follows: 'Configuration value'                                                                                                                                                                                                                                                                                                 'LANG_AUTO_DETECT' => true, // Automatically detect language 'DEFAULT_LANG' 'DEFAULT_LANG' => 'zh-cn', // Default language 'LANG_LIST' 'LANG_LIST' => 'en-us,zh-cn,zh-tw', //Must write a list of allowed languages 'VAR_LANGUAGE' => 'l', // Default language switching variable ); ?> ​ ​ 2. Add a php file (tag.php) to the conf folder of Home and add the following code: ​ The code is as follows: return array( // Just add the following line of definition 'app_begin' => array('CheckLang') ); ​ ​ 3. Copy the Extend/Behavior/CheckLangBehavior.class.php file to Home/lib/Behavior/ (only the full version of thinkphp package is available, if not, please create it yourself) ​ CheckLangBehavior.class.php code: ​ The code is as follows: true, // Automatically detect language. Valid after turning on multi-language function 'Lang_list' = & gt; 'zh-cn', // The language list that allows switching is separated in a comma 'Var_language' = & gt; 'l', // default language switch variable ); ​ //The execution entry of behavioral extension must be run Public function run(&$params){ // Enable static cache $this->checkLanguage(); } ​ /*** Language check * Check the browser supported languages ​​and automatically load the language pack * @access private * @return void ​​*/ private function checkLanguage() { //Do not enable the language pack function, just load the framework language file and return directly If (!C('LANG_SWITCH_ON')){                  return; } } $langSet = C('DEFAULT_LANG'); // Language pack function is enabled // Get the language selection based on whether automatic detection settings are enabled If (C('LANG_AUTO_DETECT')){ If(isset($_GET[C('VAR_LANGUAGE')])){                       $langSet = $_GET[C('VAR_LANGUAGE')];//The language variable is set in the url Cookie('think_language',$langSet,3600);           }elseif(cookie('think_language')){// Get the last user’s choice                     $langSet = cookie('think_language');           }elseif(isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])){//Automatically detect browser language                        preg_match('/^([a-zd-]+)/i', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $matches);                      $langSet = $matches[1]; Cookie('think_language',$langSet,3600);           }                    if(false === stripos(C('LANG_LIST'),$langSet)) { // Illegal language parameter                     $langSet = C('DEFAULT_LANG');           } } }// Define the current language             define('LANG_SET',strtolower($langSet)); ​           $group = ''; $path = (defined('GROUP_NAME') && C('APP_GROUP_MODE')==1) ? BASE_LIB_PATH.'Lang/'.LANG_SET.'/' : LANG_PATH.LANG_SET.'/'; // Read the project public language package If(is_file(LANG_PATH.LANG_SET.'/common.php'))           L(include LANG_PATH.LANG_SET.'/common.php'); // Read the grouped common language package If(defined('GROUP_NAME')){                  if(C('APP_GROUP_MODE')==1){ // Independent grouping                      $file = $path.'common.php';           }else{ // Ordinary grouping                      $file = $path.GROUP_NAME.'.php';                     $group = GROUP_NAME.C('TMPL_FILE_DEPR');           }                                                                                                                                                                                                                                if(is_file($file))                       L(include $file); } } // Read the current module language package If (is_file($path.$group.strtolower(MODULE_NAME).'.php'))               L(include $path.$group.strtolower(MODULE_NAME).'.php'); } } ​ ​ ​ 4. Create 3 language folders under the lang folder in Home. They are zh-cn en-us zh-tw, ​ Create a common.php file in each of these three folders, as shown in the figure: ​ In common.php, write the corresponding ​ The code is as follows: 'Welcome to use thinkphp', ); ?> The code is as follows: 'Welcome to ThinkPHP', ); ?> ​ The code is as follows: 'Welcome to ThinkPHP', ); ?> ​ ​ 5. Create the view index.html under the tpl/Index/ folder ​ The code is as follows: ​ ​ Done! ​ If you want to switch the background language, add L before each sentence, such as: ​ The code is as follows: public function index(){ print L('add_user_error'); //add_user_error is just a language variable, the specific language must be written in the language package $this->display(); } ​ ​ I think cakephp does this better. There is no need to give a variable to every sentence.
