PHP操作SQLITE

今天介绍一个可以操作SQLITE2,和SQLITE3的PHP类,此为我封装的。

<?php abstract class Db{
	
	public static function factory($type){
		return call_user_func(array($type , &#39;getInstance&#39;));
	}
	//查询
	public abstract function getArray($query);
	//执行SQL
	public abstract function exec($query);
	//获取此次插入的ID
	public abstract function getInsertId($query);
}
Copy after login

class Sqlite extends Db{
	
	private static $link = null;
	
	private $conn = null;
	
	private $pdo  = null;
	
	private function __construct(){
		$conf = Config::to();
		$sqliteDsn = 'sqlite2:'.TM_PATH.'data'.DS.'csxyzs.db';//SQLITE文件路径,如果在服务器上,请改用绝对路径
		$this->pdo  = new PDO($sqliteDsn);//采用PDO操作
	}
	
	public static function getInstance(){
		if(is_null(self::$link)){
			self::$link = new self();
		}
		return self::$link;
	}
	
	public function getArray($query){
		$return  = array();
		$rs = $this->pdo->query($query) or die(print_r($this->pdo->errorInfo(), true));
		$return = $rs->fetchAll();
		return $return;
	}
	
	public function exec($query){
		$result = $this->pdo->exec($query) or die(print_r($this->pdo->errorInfo(), true));
		return $result;
	}
	
	public function getInsertId($query){
		$result = $this->pdo->exec($query);
		return $result;
	}
	
}
Copy after login

如果想使用上述代码,只要在你的项目中引入这两个文件,或这两段代码。
$db = Db::factory('Sqlite');
$db->getArray('select * from table');
$db->exec('insert into table values("aa" , "bb")');
Copy after login

不过如果要使用PDO,请确保你的服务器支持如下显示。
