PHP 读取 XML 类《PHP XML Library, version 1.2b》

Submitted by 孤魂 on 2009, March 31, 11:15 AM

昨天申请了阿里妈妈淘客广告的API，客服告诉我需要两三天的时间才可以审核下来，不知道运气如何了，呵呵，API一般都是XML传递数据来的，所以先发一个比较好用的PHP XML读取类。

今天晚上更新了本机的PHP环境配置，刚才去下载APMServ的时候，发现张宴也推荐了这个PHP读取XML的类，不过他写得更详细，还有使用方法来的，如果不知道怎么样使用的朋友可以参考参考：http://blog.s135.com/post/253/

PHP5中简洁实用的SQLITE操作类

Submitted by 孤魂 on 2009, March 29, 7:52 PM

PHP5中有2种连接sqlite的方法。一种是默认提供的，另一种是PDO类。默认的只支持sqlite2，但是PDO可以间接支持sqlite3。面是泡菜写的简单的PDO类可以兼容2个版本，个人感觉很实用，所以转载过来了！

PHP代码

class SQLite{
function __construct($file){
try{
$this->Connection=new PDO('sqlite2:'.$file);
}catch(PDOException $e){
try{
$this->Connection=new PDO('sqlite:'.$file);
}catch(PDOException $e){
exit('error!');
}
}
}
function __destruct(){
$this->Connection=null;
}
function Query($SQL){
return $this->Connection->Query($SQL);
}
function Execute($SQL){
return $this->Query($SQL)->fetch();
}
function RecordArray($SQL){
return $this->Query($SQL)->fetchAll();
}
function RecordCount($SQL){
return count($this->RecordArray($SQL));
}
function RecordLastID(){
return $this->Connection->lastInsertId();
}
}

然后实例化，在实例化中如果数据库存在就自动打开，不存在就会自动创建数据库。

PHP代码

$DB=new SQLite('blog.db'); //这个数据库文件名字任意

创建数据库表。

PHP代码

$DB->Query("create table test(id integer primary key,title varchar(50)");

接下来添加数据。

PHP代码

$DB->Query("insert into test(title) values('泡菜')");
$DB->Query("insert into test(title) values('蓝雨')");
$DB->Query("insert into test(title) values('Ajan')");
$DB->Query("insert into test(title) values('傲雪蓝天')");

之后就是如何读取数据了，也就是循环。

PHP代码

$SQL='select title from test order by id desc';
foreach($DB->Query($SQL) as $RS){
echo $RS['title'];
}

PHP无敌之运行CMD命令功能

Submitted by 孤魂 on 2009, March 24, 11:28 PM

前天还讲Google Apps 的自定义域名服务器已经解封，今天就发现已经失效了，万恶的GFW。今天搜索了一下没有封的IP，但是IP列表太多，其实部分已经封掉了，所以得一个一个的PING，结果在PHP中找到了这条命令，可以使用PHP自动PING IP，校检网络连接是否正常！下面就是简单的一个例子，可能只能在WINDOWS服务器下面使用了。最后想想，还可以使用PHP执行其它EXE命令呢，所以如果要在服务器上用的话，特别注意安全，嘿嘿！
