You can just call any of these functions. After the file is included, the functions will be placed in the global scope.
您可以只调用这些函数中的任何一个。包含文件后，函数将放置在全局范围内。
have you not tried:
你有没有试过：
include "Services.php";
$num = 123;
serv1($num);
From the doc:
从文档：
When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables available at that line in the calling file will be available within the called file, from that point forward. However, all functions and classes defined in the included file have the global scope.
当一个文件被包含时，它包含的代码继承了包含发生所在行的变量范围。从那时起，调用文件中该行可用的任何变量都将在被调用文件中可用。但是，包含文件中定义的所有函数和类都具有全局作用域。

Just call them the same as you would any other function:
只需像调用任何其他函数一样调用它们即可：
serv1(42);
回答by Chiggins
You should just be able to call serv2(3)or whatever need be.
你应该能够打电话serv2(3)或任何需要。
