用于循环的函数[关闭]

Question

While I am practicing for PHP I want to make a function with PHP for loop

function Yearsbox(,) {
    for ($i=2000; $i < 2020 ; $i++) { 
        echo $i;
    }
 }
 echo Yearsbox;

What is wrong?

Answer 1

You may not give a single comma as an argument to the function. Either give your parameter a valid name or leave the brackets empty.

Second, you call a function with brackets (forget what i wrote before, you have to add them, otherwise php interprets it as a constant)

This is what should work:

function Yearsbox() {
    for ($i=2000; $i < 2020 ; $i++) { 
        echo $i;
    }
 }
 Yearsbox();
