Thinkphp The L Method usage Introduction _php Tutorial

The thinkphp L method is used to enable multi-language scenarios, setting and getting the current language definition.
Its invocation format is: L (' language variable ' [, ' language value '])

1. 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:

L (' Lang_var ', ' language definition ');

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

L (' Lang_var ', ' language definition ');

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: $lang [' lang_var1 '] = ' language definition 1 '; $lang [' lang_var2 '] = ' language definition 2 '; $lang [' lang_var3 '] = ' language definition 3 '; L ($lang);

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

2. Get language variables

$langVar = L (' Lang_var ');

Or:

$langVar = L (' Lang_var ');

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

$lang = L ();

Or we can use it in a template.

{$Think. Lang.lang_var}

To output the language definition.
