Fourth, function

Addition operation, run result: 4

Fifth, scope

Local variables: variables defined within a function

Global variables: variables defined outside the function, global

Static variables: function internal definition, static, initialized only when the function is used for the first time

VI. Function parameters

Func_get_args (); gets an array of function parameters

Func_get_arg (); get the parameter content, starting with subscript 0

Func_num_args (); get the number of parameters

Running result:

Array ([0] = > Jay [1] = > waiting for the class to be over [2] = > Don't cry) 1JayMurray-wait for the class to be over

Variable function that assigns the function name to the variable

Running result: 4
