根据 Mysql里的字段自动生成类文件的实现代码,学习php的朋友可以参考下。

根据 Mysql 里的字段 自动生成 类文件：

但需要导入：

require_once ./db/ez_sql_core.php;

require_once ./db/ez_sql_mysql.php;

帮助文档：

上图 ：

核心代码:

代码如下:

$meta = mysql_fetch_field($rel);

if($meta){

if($meta->primary_key==1){

$this->primary_key = $meta->name;

}else{

$fieldname[$v] = $meta->name;

$v++;

}

}

}

mysql_close();

return $fieldname;

}

public function showclass($databasename,$tablename){

$field = $this->field_list($databasename,$tablename);
