真正的PHP面向对象是什么样子？
<?php
class Article
{
private $title;
private $body;
private $a_datetime;
private $db;
function set($title, $body, $a_datetime)
{
$this->title = $title;
$this->body = $body;
$this->a_datetime = $a_datetime;
}
public function add_article($uid)
{
$sql = "insert into article values(NULL, '".$this->title."','".$this->body."','".$this->a_datetime."','".$uid."')";
$this->db = new BC_DB;
$this->db->bc_query($sql);
}
public function edit_article($aid)
{
$sql = "update article set title='".$this->title."',body='".$this->body."'where aid='".$aid."'";
//echo $sql;
$this->db = new BC_DB;
$this->db->bc_query($sql);
}
public function del_article($aid)
{
$sql = "delete from article where aid='".$aid."'";
$this->db = new BC_DB;
$this->db->bc_query($sql);
}
public function get_article($aid)
{
$sql = "select title, body, a_datetime from article where aid = '". $aid ."'";
//echo $sql;
$this->db = new BC_DB;
$this->db->bc_query($sql);
$row = $this->db->getRow();
return $row;
}
public function show_edit_form($action, $aid='',$title='',$body='',$a_datetime='')
{
?>
<form id="form"method="post" action=edit.php?action=<?php echo $action?>>
<input type=hidden name=aid value=<?php echo $aid?>>
<input type=hidden name=a_datetime value=<?php echo $a_datetime?>>
<p><label for="title">标题</label><input id="title"type="text" size=65 name="title" value=<?php echo $title?>></p>
<p><label for="body">正文</label><textarea id="body" cols = 50 rows = 20 name="body"><?php echo $body?></textarea></p>
<p><label for="submit"><input id="submit"type=submit value=提交></label></p>
</form>
<?php
}
public function list_article($start=0,$pagesize=5)
{
$sql = "select aid,title, body, a_datetime, uid from article order by aid limit ".$start.",".$pagesize."";
//echo $sql;
$this->db = new BC_DB;
$this->db->bc_query($sql);
while ($rows = $this->db->getRow())
{
$contents[] = $rows;
}
return $contents;
}
public function page_nave($pagesize=0)
{
for ($i = 1; $i<10; $i++)
{
echo '|';
echo '<a href='.basename($_SERVER[PHP_SELF])."?action=list_article&p=$i>",$i,'</a>';
}
}
}
?> 尝试写了几个类，发现写出来的不过是一些函数的包装器,而且基本上是重复插入，删除，修改操作，这样的类有必要么？真正的PHP面向对象是什么样子？
