从PHP5.0开始可以使用mysql(i), 是一个面向对象的技术（新加功能都会以对象形式添加）i:表示改进，1. 功能增加了， 2，效率大大增加（以后的PHP项目改成mysqli）,3，更稳定mysqli使用面向对象技术，但也支持过程化的使用方式mysqli扩展中给我提供了三个类：1. mysqli和连接有关的类2. mysql

//step 1$link=mysql_connect("localhost", "root", "123456") or die("connect error!");//step 2mysql_select_db("xsphpdb") or die("select db error!");function table($tabname) {//execute

//step 1$link=mysql_connect("localhost", "root", "123456") or die("connect error!");//step 2mysql_select_db("xsphpdb") or die("select db error!");//execute SQL$sql="select id, name, pric

一、介绍SESSIO信息写入到自己定义的位置1. 解决跨机保存SESSION在Linux下可以使用nfs或是samba, 共享文件夹的方式使用数据库来实现memcache来保存会话信息session_set_save_handler()2. 解决在线用户信息二、介绍一下PHP配置文件中的常用选择(PHP.in) （写个

//step 1$link=mysql_connect("localhost", "root", "123456") or die("connect error!");//step 2mysql_select_db("xsphpdb") or die("select db error!");function table($tabname) {//execute

memcache一、Memcache概述Memcache(内存，缓存) ： 是一个高性能的分布式的内存对象缓存系统。通过在内存里维护一个巨大的hash表。 （key=value）Hash表keyvaluemystr“abc”myarrArray(“aa”, “cc”);

$link = mysql_connect('localhost:9527', 'root', 'root');if (!$link) {    die('Could not connect: ' . mysql_error());}echo 'Connected successfully';mysql_select_db("hmiss"); $array1 = mysql

如果先安装mysql，在安装php，两者前后都是一样的，无所谓先后]#  ./configure --prefix=/usr/local/web/php/ --with-apxs2=/usr/local/web/apache/bin/apxs --with-libxml-dir=/usr/local/web/libxml/ --with-mysql=/usr/bin/ --with-libdi

$mysqli=new mysqli("localhost", "root", "123456", "xsphpdb");//有结果集多个select语句$sqls="select current_user();";$sqls.="desc shops;";$sqls.="select * from shops;";$sqls.="select current_date

$mysqli=new mysqli("localhost", "root", "123456", "xsphpdb");//事务处理$mysqli->autocommit(0);$error=true;$price=50;$sql="update zh set ye=ye-{$price} where name='zhangsan'";

try{        $pdo=new PDO("mysql:host=localhost;dbname=xsphpdb", "root", "123456");        $pdo->setAttribute(PDO::ATTR_ERRMODE,  PDO::ERRMODE_WARNING);    }catch(PDOException $e){        echo

PHP安装  需要先安装apahe，和libxml2，安装php还需要安装perlhttp://blog.youkuaiyun.com/zhuixunhebe1/article/details/21157279apache安装这里不做介绍，上个文章有，这里只说安装libxml2 perl1.获取安装文件： http://www.php.net/downloads.php   http://cn
