How to use the L method in thinkphp

The L method of thinkPHP is used to set and get the current language definition when multiple languages ​​are enabled.

The calling format is: L('Language variable'[,'Language value'])

1. Set the language variable

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

L('LANG_VAR','语言定义');

The language definition is not case-sensitive, so the following is also equivalent:

L('LANG_VAR','语言定义');

However, for the sake of standardization, we recommend uniform adoption Upper case defines language variables.

L method supports batch setting of language variables, for example:

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

means setting three language variables lang_var1 lang_var2 and lang_var3 at the same time.

2. Get the language variables

$langVar = L('LANG_VAR');

Or:

$langVar = L('LANG_VAR');

If the parameter is empty, it means to get all the currently defined language variables (including those in the language definition file):

$lang = L();

Or we can also use

{$Think.lang.lang_var}

in the template to output the language definition.
