function globalFunctionWithParameters($parameter1, $parameter2){ // 具体代码 } “` 在上面的示例中,我们定义了一个名为`globalFunctionWithParameters`的全局函数,并传递了两个参数`$parameter1`和`$parameter2`。 ### 全局函数的返回值 全局函数可以有一个返回值。返回值是函数执行后产生的结果,可以使用`ret...
Let's break it down. The name of the parameter ($str) is given in parentheses. Since we don't know which value is being worked with within functions, parameters are always described as variables. The name of the parameter can be anything, it's not related to how the function is called...
Function Parameters (Programming PHP)Rasmus LerdorfKevin Tatroe
PHP has a mechanism to enforce the types of function parameters, and to accept parameters either by reference or by value. In the earlier examples, we had not yet used that mechanism, and we left it to the function implementations to inspect the 'Php::Parameters' object (which is a std:...

function createPerson(string $name, int $age, string $gender) { // 创建一个人员对象}// 使用命名参数调用函数createPerson(name: "Tom", age: 18, gender: "male");在上面的例子中，我们通过参数名 => 值的方式来传递函数的参数。这样可以让代码更加清晰易懂，特别是在函数参数较多时。命名参数必须...
