php - 如何在 drupal 7 中定义模块级变量

Question

如何在 drupal 模块中定义变量，以便我可以从任何函数访问该模块中的那些变量

Answer 1

尝试 variable_set () 和 variable_get ()

像这样设置变量:

// I have assumed the variable name to be "the_name_of_the_variable"
variable_set("the_name_of_the_variable", "the value of the variable");

然后像这样检索值:

$my_variable = variable_get("the_name_of_the_variable", "a default value in case the variable has never been set before");
