thinkphp function: L method

The L method is used to enable multiple languages, setting and getting the current language definition.
Call format:L (' language variable ' [, ' language value '])
Setting language variables
In addition to using language packs to define language variables, we can dynamically set language variables using the L method, for example:

1. L(‘LANG_VAR‘,‘语言定义‘);

复制代码

Language definitions are not case-sensitive, so the following are equivalent:

1. L(‘lang_var‘,‘语言定义‘);

复制代码

But for the sake of specification, we recommend using uppercase to define language variables uniformly.
The L method supports batch setting of language variables, such as:

1. $lang[‘lang_var1‘] = ‘语言定义1‘;
2. $lang[‘lang_var2‘] = ‘语言定义2‘;
3. $lang[‘lang_var3‘] = ‘语言定义3‘;
4. L($lang);

复制代码

Represents the simultaneous setting of 3 language variables Lang_var1 lang_var2 and LANG_VAR3.

Get language variables

1. $langVar = L(‘LANG_VAR‘);

复制代码

Or:

1. $langVar = L(‘lang_var‘);

复制代码

If the argument is empty, it means getting all of the currently defined language variables (including the language definition file):

1. $lang = L();

复制代码

Or we can use it in a template.

1. {$Think.lang.lang_var}

复制代码

To output the language definition.
