具有函数definiiton的类 [英] Class with function definiiton
本文介绍了具有函数definiiton的类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图提取在segment.php中从类段定义的所有函数的内容。从home_segment.php中的类段调用所有三个函数这是从一个类调用多个函数的正确方法。
或建议使用良好的OOP概念。如何改进面向对象编程中的上述类似功能。
我尝试过：
< br $>
segment.php
I was trying to pullout the content of all the functions defined from the class segment in segment.php. And calling all the three functions from a class segment in home_segment.php Is this a correct way of calling multiple functions from one class.
Or suggest with good OOP's concept. How could I improve the above similar functionality in Object Oriented Programming.
What I have tried:
segment.php
<?php
$mysqli = mysqli_connect("localhost","root","","squarellt");
$cid = required_param('id', PARAM_INT);
class segment
{
public function unitseg_set1()
{
$subject = $mysqli->query('SELECT * FROM order_subject WHERE id='.$cid.'');
while($row=$subject->fetch_array() )
{
echo '<div>'.$row['chem_name'].'</div>';
}
}
public function unitseg_set2()
{
$subject = $mysqli->query('SELECT * FROM order_subject WHERE id='.$cid.'');
while($row=$subject->fetch_array() )
{
echo '<div>'.$row['physiotherapy_nn'].'</div>';
}
}
public function unitseg_set3()
{
$subject = $mysqli->query('SELECT * FROM order_subject WHERE id='.$cid.'');
while($row=$subject->fetch_array() )
{
echo '<div>'.$row['commun_gg'].'</div>';
}
}
}
?>
home_segment.php
home_segment.php
require_once('segment.php');
$acc = new segment();
$account1 = $acc->unitseg_set1();
$account2 = $acc->unitseg_set2();
$account3 = $acc->unitseg_set3();
echo $account1;
echo $account2;
echo $account3;
推荐答案
mysqli = mysqli_connect（ localhost， root， ， squarellt）;
mysqli = mysqli_connect("localhost","root","","squarellt");
cid = required_param（' id'，PARAM_INT）;
class segment
{
public function unitseg_set1（）
{
cid = required_param('id', PARAM_INT); class segment { public function unitseg_set1() {
subject =
subject =
