在線客服代碼，qq，msn，skype，淘寶旺旺，阿里巴巴貿(mào)易通，雅虎通
in: 網(wǎng)站前端
1.QQ在線咨詢代碼
(qq在線交談代碼/qq在線客服代碼/qq在線狀態(tài)代碼/qq在線客服代碼)
(將66757924換成你的號(hào)碼,site后面換成你的網(wǎng)站就可以了)
<a target="blank" href="http://wpa.qq.com/msgrd?V=1&Uin=66757924&Site=服務(wù)易& Menu=yes"><img border="0" SRC=http://wpa.qq.com/pa?p=1:66757924:6 alt="點(diǎn)擊這里給我發(fā)消息" align="absmiddle"></a>
2.MSN在線咨詢代碼
用的時(shí)候把[郵件地址]寫成你的MSN賬號(hào)，不要方括號(hào)，用鏈接即可，如
<a target="blank" href="msnim:chat?contact=sliang@zui88.com">MSN在線客服</a>
3.skype在線狀態(tài)代碼生成
將yisung換成你的skype ID就可以了,需要在skype個(gè)人賬戶里設(shè)置對(duì)任何人顯示狀態(tài)
<a target="blank" href="skype:mengsajewel?call"><img src=http://mystatus.skype.com/smallclassic/yisung style="border: none;" alt="Call me!" /></a>
更多的skype在線狀態(tài)代碼生成樣式,請(qǐng)查看skype的官方網(wǎng)站

phpmyadmin導(dǎo)出的sql如何通過php導(dǎo)入
in: 后端程序
以下函數(shù)可以直接把從phpmyadmin導(dǎo)出的sql文件直接通過php插入數(shù)據(jù)庫：
//$file表示通過讀取sql文件返回的字符串，比如$file2=file_get_contents('db.sql');
function import($file2){
$Db = new Db();
$file2=explode("\n",$file2);//將文件內(nèi)容按行讀入到數(shù)組
$c1=count($file2);
for($j=0;$j<$c1;$j++)
{
$ck=substr($file2[$j],0,4);//取每行的前4個(gè)字符
if( ereg("#",$ck)||ereg("--",$ck) )//去掉注釋
{
continue;
}
$arr[]=$file2[$j];//將去掉注釋的文件內(nèi)容按行讀入數(shù)組$arr,數(shù)組每個(gè)元素對(duì)應(yīng)一行
}
$read=implode("\n",$arr); //重新組織文件內(nèi)容到一個(gè)字符串,(按照原來分好的一行一行的)
$sql=str_replace("\r",'',$read);//去掉"\r(回車符)"
$detail=explode(";\n",$sql);
//將經(jīng)上述整理過的文件內(nèi)容再次按一條完整的sql語句(以;和\n分隔)導(dǎo)入到數(shù)組$detail,
//此時(shí)數(shù)組detail的每個(gè)元素對(duì)應(yīng)一條完整的sql語句
$count=count($detail);
for($i=0;$i<$count;$i++)
{
$sql=str_replace("\r",'',$detail[$i]);//去掉每行sql中的回車符
$sql=str_replace("\n",'',$sql);//去掉換行符
$sql=trim($sql);//去掉前后空格
//現(xiàn)在的$sql
$Db->query($sql);
}

php date函數(shù)的時(shí)區(qū)問題，輸出時(shí)間有誤
in: 后端程序
問題：echo date('o-m-j H:i'); 輸出結(jié)果與本地時(shí)間相差8小時(shí)。
原因：時(shí)區(qū)未正確設(shè)置。
兩種解決方法:
1.加入date_default_timezone_set('Asia/Shanghai');
2. 修改php.ini
[Date]
; Defines the default timezone used by the date functions
date.timezone = PRC 注:PRC為中化人民共和國

php采集程序，提取網(wǎng)頁超鏈接，郵箱或其他特定內(nèi)容
in: 后端程序
以下代碼從上一篇文章修改而來，專門用于提取網(wǎng)頁所有超鏈接，郵箱或其他特定內(nèi)容
<?php
function fetch_urlpage_contents($url){
$c=file_get_contents($url);
return $c;
}
//獲取匹配內(nèi)容
function fetch_match_contents($begin,$end,$c)
{
$begin=change_match_string($begin);
$end=change_match_string($end);
$p = "#{$begin}(.*){$end}#iU";//i表示忽略大小寫，U禁止貪婪匹配
if(preg_match_all($p,$c,$rs))
{
return $rs;}
else { return "";}
}//轉(zhuǎn)義正則表達(dá)式字符串
function change_match_string($str){
//注意，以下只是簡單轉(zhuǎn)義
$old=array("/","$",'?');
$new=array("\/","\$",'\?');
$str=str_replace($old,$new,$str);
return $str;
}
//采集網(wǎng)頁
function pick($url,$ft,$th)
{
$c=fetch_urlpage_contents($url);
foreach($ft as $key => $value)
