Introduction to the L method of ThinkPHP

The L method of thinkPHP is used to set and obtain the current language definition when multiple languages are enabled.
The call format is L ('language variable '[, 'language value']).

1. Set language Variables

In addition to defining language variables using language packs, we can use the L method to dynamically set language variables, for example:

L ('lang _ var', 'language defination ');

The language definition is case insensitive, so the following is equivalent:

L ('lang _ var', 'language defination ');

However, we recommend that you define language variables in uppercase.

L The method supports batch setting of language variables, for example, $ lang ['lang _ var1'] = 'language definition 1 '; $ lang ['lang _ var2'] = 'language definition 2'; $ lang ['lang _ var3'] = 'language definition 3'; L ($ lang );

Set the lang_var1 lang_var2 and lang_var3 language variables.

2. Get language Variables

$ LangVar = L ('lang _ var ');

Or:

$ LangVar = L ('lang _ var ');

If the parameter is blank, it indicates obtaining all the language variables defined currently (including in the language definition file ):

$ Lang = L ();

Or we can use it in the template.

{$ Think. lang. lang_var}

Output language definition.
