老discuz直接升级至discuz x2

qlj — Mon, 12 Mar 2012 12:37:16 +0000

我这个是discuz 6.1吧。大概。。
版本忘记了。。
是gbk版本。
老论坛。在我17岁那年玩的
由于当时未满18.。随便上网搜了个身份正。。拿去 beian了。
后来beian重申。。
哪能记得当时用的谁的。。。
就这样。。 beian被取消了。。
无奈啊。

现在放国外服务器上挂着吧。

似乎转换有点麻烦
决定一个个表的手工转换

php邮件发送类推荐 PHPMailer:smtp法

qlj — Wed, 25 May 2011 19:48:11 +0000

这里说明下我用的是SMTP 其他方法的请继续 GOOGLE
刚拿到的时候测试了下发信无异常支持HTML
但是SMTP 发送的过程中需要先于SMTP 服务器建立连接然后发信
这个过程可能需要1-3秒可能会导致网页响应较长时间
所以呢. 我们建立一个表用于存放发送的邮件队列
每次发送邮件是将邮件内容加入表中
然后用CRON 每分钟检查下表若存在则队列发送
目前在起哄网上使用中.用于发送EMAIL认证邮件

 
--
-- 表的结构 `qlj_sendmail`
--
 
CREATE TABLE IF NOT EXISTS `qlj_sendmail` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `email` VARCHAR(50) DEFAULT NULL,
  `subject` VARCHAR(120) DEFAULT NULL,
  `body` text,
  `error` tinyint(1) NOT NULL DEFAULT '0',
  `dateline` INT(11) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

#!/usr/local/php/bin/php -q

include_once('mysql.class.php');
include_once('class.phpmailer.php');
$mail                = new PHPMailer();
$db = new DB;
$db->connect('', '', '', '');
$mail->IsSMTP(); 
	$mail->Host = "";  //SMTP服务器
	$mail->Username = "no-reply@qihoon.com";  
	$mail->Password = "";    
	$mail->FromName =  "起哄网信使";   
	$mail->SMTPAuth = true;          
	$mail->From = $mail->Username;
	$mail->CharSet = "utf8";           
	$mail->Encoding = "base64"; 
	$mail->AddAddress($sendto_email);  
$result=$db->query("SELECT id,email,subject,body FROM `qlj_sendmail` where error='0' LIMIT 0 , 30");
if($db->num_rows($result)<1) exit(); 
while ($row =$db->fetch_array($result)) {
$mail->AltBody ="text/html"; 
$mail->Subject = $row['subject'];
$mail->MsgHTML($row['body']);
  $mail->AddAddress($row["email"], $row["full_name"]);
  if(!$mail->Send()) {
    //$errorid[]=array(id=>$row['id'],error=>$mail->ErrorInfo);//本来想记录出错信息的.但是表是INT 不浪费字段了.
	  $errid[]=$row['id'];
  } else {
     $okid[]=$row['id'];
  }
  $mail->ClearAddresses();
}
if(count($okid)>0){
	$sok=implode(',',$okid);
	$db->query("delete from `qlj_sendmail` where id in($sok) ;");
	}
	if(count($errid)>0){
	$serr=implode(',',$errid);
	$db->query("update `qlj_sendmail` set error='1' where id in($serr) ;");
	}
?>

最后在 CRONTAB中加入每分钟的计划任务

php延时更新点击数[文件缓存]

qlj — Tue, 08 Mar 2011 16:56:05 +0000

想法来源

用户积分增加

列入用户访问空间时增加1分

用户首次登陆增加10分

那么每次操作都要insert一次

这显然很浪费

如果可以缓存一次性写入那么就可以降低MYSQL的压力了

像上面的情况我只要一次性增加11分即可

在THINKPHP中找到了方法

下面代码转载自THINKPHP(advmodel.class.php)

setLazyInc($field,$condition='',$step=1,$lazyTime=0) { //缓存累加
        if(empty($condition) && isset($this->options['where']))
            $condition   =  $this->options['where'];
        if(empty($condition)) { // 没有条件不做任何更新
            return false;
        }
        if($lazyTime>0) {// 延迟写入
            $guid =  md5($this->name.'_'.$field.'_'.serialize($condition));
            $step = $this->lazyWrite($guid,$step,$lazyTime);
            if(false === $step ) return true; // 等待下次写入
        }
        return $this->setField($field,array('exp',$field.'+'.$step),$condition);
    }
 
function lazyWrite($guid,$step,$lazyTime) {   
        if(false !== ($value = F($guid))) { // 存在缓存写入数据
            if(time()>F($guid.'_time')+$lazyTime) {
                // 延时更新时间到了，删除缓存数据 并实际写入数据库
                F($guid,NULL);
                F($guid.'_time',NULL);
                return $value+$step;
            }else{
                // 追加数据到缓存
                F($guid,$value+$step);
                return false;
            }
        }else{ // 没有缓存数据
            F($guid,$step);
            // 计时开始
            F($guid.'_time',time());
            return false;
        }
    }

上面有个 FUNCTION F 在FACTIONS.PHP

// 快速文件数据读取和保存 针对简单类型数据 字符串、数组
function F($name,$value='',$path=DATA_PATH) { //修改$path为自己的缓存路径
    static $_cache = array();
    $filename   =   $path.$name.'.php';
    if('' !== $value) {
        if(is_null($value)) {
            // 删除缓存
            return unlink($filename);
        }else{
            // 缓存数据
            $dir   =  dirname($filename);
            // 目录不存在则创建
            if(!is_dir($dir))  mkdir($dir);
            return file_put_contents($filename,"\nreturn ".var_export($value,true).";\n?>");
        }
    }

调用方法

setLazyDec($field,$condition='',$step=1,$lazyTime=0) 
//根据需要 自己修改吧我加入了table 等多个
function lazyaddint($table,$field,$condition='',$num=1,$ltime=0)
//调用方法 更具实际需要修改吧
lazyaddint('表明','字段名',"WHERE条件",增加数量,缓存时间);

此方法会在缓存目录中创建2个临时文件

//07e8c1b06dbdc4f282bf7bf9311a1fce_time.php

return 1299602761;
?>
 
//07e8c1b06dbdc4f282bf7bf9311a1fce.php

return 21;
?>

根据时间超过设定的时间就写入数据库
此方法已经适用无问题
感觉方法不太好.. 期待MEMCACHED的方式

smarty cache缓存的使用

qlj — Wed, 19 May 2010 18:46:00 +0000

机器实在太老了。。
在增加到8W条文章
TAG表已经增加到了30多万条了
10 个表总计 415,762
在我那个老电脑上。。（p4 1.6 256内存）
很快。。内存不足了。。只剩下4MB剩余内存
于是TAOBAO上买了个 512的SDRAM

MYSQL 真是个费劲的家伙

原本将一些列表等。缓存了。已减少查询。。在5W文章内。还不是很吃力
没想到到了8W后。要等好几秒才刷出来。。而PHP显示的执行时间却依然是不到0.2秒
在加内存后。
已经可以正常运行了。
但是看CPU使用率还是挺高的于是决定。直接使用SMARTY缓存

首页缓寸一天

$Smarty -> caching=true;
$Smarty->cache_lifetime = 86400;
if(!$Smarty->is_cached('index.html')){
 
......
 
}
 
//文章页 缓存 1周
$Smarty -> caching=true;
$Smarty->cache_lifetime = 7*86400;
if(!$Smarty->is_cached('article.php',$id)){
}

为了防止把执行速度也CACHE了

function nocache_block($params,$content,Smarty $Smarty){
	return $content;
	}
	$Smarty -> register_block('nocache','nocache_block',false);

调用

	>
	Processed in  >

引用另一种防止CACHE的方法

1、使用insert函数使模板的一部分不被缓存

首先在php页面中


 function insert_get_now_time()
 {
  return date("Y-m-d h:i:s",time()+3600*8);
 }
 
 
 
 
 
?>
//html调用方法
现在时间为：<{insert name="get_now_time"}>

意：首先函数命名一定要以 insert_ 开头后面紧跟着模版中的函数名字
只要定义了函数 smarty 会自动加载其函数。

另一种
2使用register_function阻止插件从缓存中输出

 
index.tpl:
<div>{current_time}div>
 
index.php:
function smarty_function_current_time($params, &$smarty){
    return date("Y-m-d H:m:s");
}
 
$smarty=new smarty();
$smarty->caching = true;
$smarty->register_function('current_time','smarty_function_current_time',false);
if(!$smarty->is_cached()){
    .......
}
$smarty->display('index.tpl');

注解：
定义一个函数，函数名格式为：smarty_type_name($params, &$smarty)
type为function
name为用户自定义标签名称，在这里是{current_time}
两个参数是必须的，即使在函数中没有使用也要写上。两个参数的功能同上。

php+mysql模仿android中短信界面的效果

qlj — Mon, 12 Apr 2010 20:11:01 +0000

十分喜欢android的短信
像 QQ一样。。
缺点是。。发消息也想QQ一样。。。
一条接一条。。钱也一条接一条的扣。。
哈哈
现在大部分网站的短信都类似于 GMAIL 一样。或者说。跟论坛主题一样。。一个贴。。后面回复。。
改变下模式。。做自己喜欢的效果。。

android短信的效果
对方号码 + 最后一条消息内容（简略） +条数
那变成站内信的效果就是
发信人资料 + 简短消息 +条数+ 最后时间
下面是PHP +MYSQL部分
觉得自己的MYSQL太烂了希望有人能看到这个贴后优化下查询过程

$query=$db->query("select * from qlj_pm where pmid in (SELECT max(pmid) FROM qlj_pm where tuid='{$qljid}' GROUP BY fuid )");
while($res=$db->fetch_array($query))
{
$count=$db->fetch_array($db->query("select count(pmid) from qlj_pm where (fuid='{$res['fuid']}' and tuid='{$qljid}') or  (fuid='{$qljid}' and tuid='{$res['fuid']}')"));
$res['count']=$count['count(pmid)'];//这个是条数
 
}

另外还有一个
看起来很帅的代码
不过貌似有问题
虽然全角是转半角了
但是有部分中文字也出错了貌似。

function &StrToDBC($str,$Encode='GBK'){
 if($Encode!='UTF8')$str=mb_convert_encoding($str,'UTF-8',$Encode);
 $ret='';
 for($i=0;$s1=$str[$i],$i<strlen($str);$i++){

PHP时间变成几秒前,几分前,几小时前,几天前SNS模式

qlj — Fri, 19 Mar 2010 15:54:05 +0000

最近模仿UCHOME的DOING
我寸在MYSQL的时间都是unix时间。

function qtime($time){
       $limit = time() - $time;
 
       if($limit<60)
       $time="{$limit}秒前";
       if($limit>=60 && $limit<3600){
            $i = floor($limit/60);
            $_i = $limit%60;
            $s = $_i;
           $time="{$i}分{$s}秒前";
       }
       if($limit>=3600 && $limit<3600*24){
            $h = floor($limit/3600);
            $_h = $limit%3600;
            $i = ceil($_h/60);
            $time="{$h}小时{$i}分前";
       }
       if($limit>=(3600*24) && $limit<(3600*24*30)){
            $d = floor($limit/(3600*24));
            $time= "{$d}天前";
        }
		if($limit>=(3600*24*30)){
            $time=gmdate('Y年n月j日', $time);
        }
		return $time;
}

使用方法：

$res['postdate']=qtime($res['postdate']);

另外分享网上其他的代码

function time_tran($the_time){
   $now_time = date("Y-m-d H:i:s",time()+8*60*60); 
   $now_time = strtotime($now_time);
   $show_time = strtotime($the_time);
   $dur = $now_time - $show_time;
   if($dur < 0){
    return $the_time; 
   }else{
    if($dur < 60){
     return $dur.'秒前'; 
    }else{
     if($dur < 3600){
      return floor($dur/60).'分钟前'; 
     }else{
      if($dur < 86400){
       return floor($dur/3600).'小时前'; 
      }else{
       if($dur < 259200){//3天内
        return floor($dur/86400).'天前';
       }else{
        return $the_time; 
       }
      }
     }
    }
   }
}

后来发现了个更简单的

function format_date($date,$isShowDate=true)
{
    $limit = time() - $date;
    if($limit < 60)
    {
        return $limit . '秒钟之前';
    }
    if($limit >= 60 && $limit < 3600)
    {
        return floor($limit/60) . '分钟之前';
    }
    if($limit >= 3600 && $limit < 86400)
    {
        return floor($limit/3600) . '小时之前';
    }
    if($limit >= 86400 and $limit<259200)
    {
        return floor($limit/86400) . '天之前';
    }
    if($limit >= 259200 and $isShowDate)
    {
        return date('Y-m-d H:i:s', $date);
    }else{
        return '';
    }
}

php jquery ajax中文乱码

qlj — Tue, 16 Mar 2010 08:12:58 +0000

PHP发送中文、Ajax接收
只需在php顶部加入一句：

header('Content-type: text/html;charset=GB2312');

xmlHttp会正确解析其中的中文。

Ajax发送中文、PHP接收
这个比较复杂：
Ajax中先用encodeURIComponent对要提交的中文进行编码
PHP中：

$view=iconv( 'UTF-8', 'gb2312//IGNORE' , $_POST['view']);

PHP使用reCAPTCHA作为验证码来保护您的网站

qlj — Mon, 15 Mar 2010 10:02:02 +0000

CAPTCHA，其全称是“全自动区分计算机和人类的图灵测试”（completely automated public Turing test to tell computers and humans apart）。
现在通过使用 Google免费的reCAPTCHA服务，您可以轻松地在您自己的网站上利用这项技术。
首先
我们需要申请一个 KEY
类似于GOOGLE MAP的API KEY一样
在reCAPTCHA网站注册一个API key(免费)。并记录下你的private key和 public key。
https://admin.recaptcha.net/accounts/signup/
然后去GOOGLE CODE 下载类库
http://code.google.com/p/recaptcha/downloads/list?q=label:phplib-Latest

调用类

require_once('recaptchalib.php');
$publickey = "..."; // you got this from the signup page
echo recaptcha_get_html($publickey);

验证部分

require_once('recaptchalib.php');
$privatekey = "...";
$resp = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],
                                $_POST["recaptcha_response_field"]);
 
if (!$resp->is_valid) {
  die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
       "(reCAPTCHA said: " . $resp->error . ")");
}

官方还提供了一个 EXAMPLE


  
    

 
require_once('recaptchalib.php');
$publickey = "...";
$privatekey = "...";
 
# the response from reCAPTCHA
$resp = null;
# the error code from reCAPTCHA, if any
$error = null;
 
# are we submitting the page?
if ($_POST["submit"]) {
  $resp = recaptcha_check_answer ($privatekey,
                                  $_SERVER["REMOTE_ADDR"],
                                  $_POST["recaptcha_challenge_field"],

xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);    
 
xml_parse_into_struct($parser, $data, $values, $index);//将 XML 数据解析到数组中    
 
xml_parser_free($parser);

    $kws[] = iconv('utf-8','gbk',$valuearray['value']);//编码转换    
 
   }    
 
}}    
 
//最后出来的是数组.    
 
print_r($kws);
