這裏是一個PHP類的例子：

class DBIGenerator{ 
    private $table; 
    private $name; 
    private $path; 
    public function __construct($table,$name='default_file.php', 
      $path='DEFAULTPATH/'){ 
     $this->table=$table; 
     $this->name=$name; 
     $this->path=$path; 
    } 
    public function generate(){ 
     // build class header 
     $str='<?php class '.$this->name.'{'; 
     if(!$result=mysql_query('SHOW COLUMNS FROM '.$this->table)){ 
      throw new Exception('Failed to run query'); 
     } 
     // build data member declaration 
     if(mysql_num_rows($result)<1){ 
      throw new Exception('Not available columns in table'); 
     } 
     $methods=''; 
     while($row=mysql_fetch_array($result,MYSQL_ASSOC)){ 
      $str.='private $'.$row['Field'].'=\'\';'; 
      $methods.='public function set'.$row['Field'].'($'.$row 
       ['Field'].'){$this->'.$row['Field'].'=$'.$row 
       ['Field'].';}'; 
      $methods.='public function get'.$row['Field'].'(){return 
       $this->'.$row['Field'].';}'; 
      // store field names in array 
      $fields[]=$row['Field']; 
     } 
     // build empty constructor 
     $str.='public function __construct(){}'; 
     // build modifiers and accessors 
     $str.=$methods; 
     // build load() method

     // build submit() method 
     $str.='public function submit(){mysql_query("INSERT INTO '.$this-

     foreach($fields as $field){

     } 
     $str.='");$this->id=mysql_insert_id();'; 
     $str=preg_replace("/,\"/","\"",$str).'}';

     } 
     $str=preg_replace("/,$/","",$str); 
     $str.=' WHERE id=\'$this->id\'");}'; 
     // build delete() method 
     $str.='public function delete(){mysql_query("DELETE FROM '. 
       $this->table.' WHERE id=\'$this->id\'");}'; 
     $str.='}?>'; 
     // open or create class file 
     if(!$fp=fopen($this->path.$this->name.'.php','w')){ 
      throw new Exception('Failed to create class file'); 
     } 
     // lock class file 
     if(!flock($fp,LOCK_EX)){ 
      throw new Exception('Unable to lock class file'); 
     } 
     // write class code to file 
     if(!fwrite($fp,$str)){ 
      throw new Exception('Error writing to class file'); 
     } 
     flock($fp,LOCK_UN); 
     fclose($fp); 
     // delete temporary variables 
     unset($fp,$str,$row,$fields,$field,$methods); 
    } 
    public function getObject(){ 
     // check if class file exists 
     if(!file_exists($this->path.$this->name.'.php')){ 
      throw new Exception('Failed to include class file'); 
     } 
     require_once($this->path.$this->name.'.php'); 
     // create data access object 
     return new $this->name; 
    } 
}

Answer 3

這是很簡單的骨架，因爲你沒有嘗試任何事情，所以才讓你有想法如何工程...

class User 
{ 
    private $id; 
    private $email; 
    // ... 

    public function __construct($id, $email...) 
    { 
     $this->id = $id; 
     $this->email = $email; 
     // ... 
    } 

    public function printAll() 
    { 
     return $this->id . ' ' . $this->email; 
    } 
}

?php 
class information 
{ 
public $id = 1; 
public $email = "npineiro9@gmail.com"; 
public $pw = "A2D7DFEA88AC88"; //Don't forget, PW are usually hashed ;) 
public function id() { 
echo $this->id; 
} 
public function email() { 
echo $this->email; 
} 
public function pw() { 
echo $this->pw; 
} 
} 
$test=new information(); 
$test->id; 
?>
