每个物业属性如何吸烟者和设置者？ [英] How have getters and setters for every property of class?

问题描述

我们不能为doctrine2实体类使用php magic getter setter，而不是为class的每个属性设置getter setter？

Can't we use php magic getter setter for doctrine2 entity classes instead of making getter setter for every property of class?

这是为doctrine2编写的实体类用数据库中的表进行映射。

This is my entity class written for doctrine2 to map with table in database.

    <?php
namespace Entities;
use Doctrine\ORM\Mapping AS ORM;

/**
 * @ORM\Entity
 */
class blogs
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer", length=11)
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=1024, nullable=true)
     */
    private $url;

    /**
     * @ORM\Column(type="string", length=512, nullable=false)
     */
    private $title;

    /**
     * @ORM\Column(type="text", nullable=true)
     */
    private $blog_data;

    /**
     * @ORM\OneToMany(targetEntity="Entities\likes", mappedBy="blogs")
     */
    private $likeses;

    /**
     * @ORM\OneToMany(targetEntity="Entities\share", mappedBy="blogs")
     */
    private $shares;

    /**
     * @ORM\OneToMany(targetEntity="Entities\comments", mappedBy="blogs")
     */
    private $commentses;

    /**
     * @ORM\ManyToOne(targetEntity="Entities\ilook_user", inversedBy="blogses")
     * @ORM\JoinColumn(name="blog_writer_id", referencedColumnName="id", nullable=false)
     */
    private $ilook_user;

    /**
     * @ORM\ManyToOne(targetEntity="Entities\blog_categories", inversedBy="blogses")
     * @ORM\JoinColumn(name="blog_categories_id", referencedColumnName="id", nullable=false)
     */
    private $blog_categories;

    public function setId($id){
        $this->id = $id;
    }
    public function getId(){
        return $this->id;
    }
    public function setUrl($url){
        $this->url=$url;
    }
    public function getUrl(){
        return $this->url;
    }
    public function setTitle($title){
        $this->title = $title;
    }
    public function getTitle(){
        return $this->title;
    }
    public function setBlog_data($blog_data){
        $this->blog_data = $blog_data;
    }
    public function getBlog_data(){
        return $this->blog_data;
    }
    public function setLikeses($likeses){
        $this->likeses=$likeses;
    }
    public function getLikeses(){
        return $this->likeses;
    }
    public function setShares($shares){
        $this->shares = $shares;
    }
    public function getShares(){
        return $this->shares;
    }
    public function setCommentses($commentses){
        $this->commentses = $commentses;
    }
    public function getCommentses(){
        return $this->commentses;
    }
    public function setIlook_user($ilook_user){
        $this->ilook_user = $ilook_user;
    }
    public function getIlook_user(){
        return $this->ilook_user;
    }
    public function setBlog_categories($blog_categories){
        $this->blog_categories = $blog_categories;
    }
    public function getBlog_categories(){
        return $this->blog_categories;
    }

}

通过魔术方法 __ set 和 __获取：

<?php
class PropertyTest
{
    private $a, $b;

    public function __set($name, $value)
    {
        echo "Set '$name' to '$value'\n";
        $this->$name = $value;
    }
    public function __get($name)
    {
        echo "Get $name \n";
        return $this->$name;
    }
}
echo "<pre>\n";
$obj = new PropertyTest;
$obj->a = 1;
echo $obj->a . "\n\n";

echo "<pre>\n";
$obj = new PropertyTest;
$obj->b = "Hello";
echo $obj->b . "\n\n";

?>

使用魔法方法编辑其他示例 __ call ：

Edit with other example using the magic method __call:

<?php
class Called {
    private $Id, $Name;

    public function __call($name, $arguments) {
        $action = substr($name, 0, 3);
        $field = substr($name, 3);

        if($action == 'set') {
            $this->$field = $arguments[0];
        }       

        if($action == 'get') {
            return $this->$field;
        }       
    }
}

$obj = new Called();
$obj->setId(4);
echo "<br/>\n";
echo $obj->getId();

echo "<br/>\n";

$obj->setName('Peter');
echo "<br/>\n";
echo $obj->getName();

?>
