php parse error, unexpected $end 的奇怪问题

[dengweiid]

描述如下：

如题错误 搜了一下 可能是 语法错误 多了{}<??> 等等

但是看了没有类似错误

另外 删除 这段：

function __destruct(){
` mysql_close($this->conId);
}

后 错误就没有了

是否 有什么秘密？

请指教

代码跟帖附上

<?php
class connection{
    public $conId = null;
	private $properties = array();
	
	function __construct(){
		$this->readConfig();
		
		$db_host = $this->properties["db_host"];
		$db_user = $this->properties["db_user"];
		$db_password = $this->properties["db_password"];
		$this->doConnection($db_host, $db_user, $db_password);
	}
	
	function __destruct(){
	`	mysql_close($this->conId);
	}
	
	
	function doConnection($db_host, $db_user, $db_password){
		$this->conId = mysql_connect($db_host, $db_user, $db_password) or die('Cannot connect to db: ' . mysql_error());
		mysql_select_db($db_name,$this->conId);
		if($this->conId){
		echo "连接成功";
		}else{
			echo "连接失败";
		}
	}
	
	function readConfig(){
		$file_handle = fopen("../web.config", "r");

				$line = fgets($file_handle);
				
				$tempArray = explode("=", $line);

				$this->properties = array_merge($this->properties , $tempArray);
			}
		fclose($file_handle);
	}
}
new connection();
?>

` mysql_close($this->conId);
