PHP 中是否有函数和/或对象和/或扩展可以让您查看当前作用域中定义的所有变量?类似的东西:

Is there a function and/or object and/or extension in PHP that will let you view all the variables defined in the current scope? Something like:

var_export($GLOBALS)

但只显示当前符号表中的变量.

but only showing variables in the current symbol table.

推荐答案

get_defined_vars

此函数返回一个多维数组，其中包含所有定义变量的列表，包括环境变量、服务器变量或用户定义变量，在 get_defined_vars() 的范围内叫.

This function returns a multidimensional array containing a list of all defined variables, be them environment, server or user-defined variables, within the scope that get_defined_vars() is called.
