OR

require "Services.php";

• How can i call its functions in myFile.php

Answer 1

您可以调用任何这些功能.包含文件后,函数将放在全局范围内.

你有没有试过:

include "Services.php";

$num = 123;

serv1($num);

来自doc:

包含文件时,它包含的代码将继承发生包含的行的变量范围.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范围.

查看这两个doc资源,了解有关您理解的内容的更多信息:

• 包括声明:http://php.net/manual/en/function.include.php
• 变量范围:http://php.net/manual/en/language.variables.scope.php

Answer 2

只需像调用其他函数一样调用它们:

serv1(42);

Answer 3

你应该只是能够打电话serv2(3)或任何需要.
