php调用不同目录的类
1、首先php把不同目录的类的相对路径存入数组，然后使用循环引入类
<?php
header('Content-type:text/html;charset=utf-8');
//spl_autoload_register()参数是匿名函数
spl_autoload_register(function($ClassName){
//将不同路径的类文件的路径放入数组中;
$arr = array(
"./$ClassName.class.php",
"./admin/controller/$ClassName.class.php"
);
// 循环不同路径的类文件的数组
foreach ($arr as $filename) {
if (file_exists($filename)) {
require_once($filename);
}
}
});2、使用new关键字创建对象并调用即可
$obj = new Student(); $obj->ShowInfo(); $obj2 = new Fruit(); $obj2->ShowInfo();
类文件:命名为Student.class.php
<?php
header('Content-type:text/html;charset=utf-8');
final class Student{
const TILTLE = "3班";
private $name = "李立";
private $age = 20;
public function __construct(){
echo "{$this->name}的年龄是{$this->age}<br>";
}
public function ShowInfo(){
echo "{$this->name}的班级是".self::TILTLE."<br>";
}
}类文件:命名为Fruit.class.php
<?php
header('Content-type:text/html;charset=utf-8');
final class Fruit{
const TILTLE = "水果类";
private $name = "苹果";
private $price = '20元/kg';
public function __construct(){
echo "{$this->name}的价格是{$this->price}<br>";
}
public function ShowInfo(){
echo "{$this->name}属于".self::TILTLE."<br>";
}
