<?php
class SimpleClass{
var $number1;
var $number2;
public function input_two_no($num1,$num2){
$this->number1=$num1;
$this->number2=$num2;
}
public function the_sum(){
$total = $number1+$number2;
return $total;
}
public function output_the_sum(){
echo $total;
}
$numbers = new SimpleClass;
$numbers->input_two_no(10,5);
$numbers->the_sum();
$numbers->output_the_sum();
}
?>
請指出我在哪裏出錯了。我還沒有得到輸出。PHP OOP通過簡單地添加兩個數字
另外,檢查$ total的變量範圍。 –
