Code Recoder

利用 LAST_INSERT_ID() 函数获取最新update或insert记录的auto_increase字段值，一般为id。例：

向users表中插入一条记录

insert into users(username, password) values('test', '1234')

获取刚新添加记录的ID，并将其插入到另一个表

insert into auth(user_id, regtime) values(LAST_INSERT_ID(), now())

$post_content = "@tvrcgo和@twitter在研究用#PHP#的#正则表达式#过滤话题和对象名";
 
$tag_pattern = "/\#([^\#|.]+)\#/";
preg_match_all($tag_pattern, $post_content, $tagsarr);
$tags = implode(',',$tagsarr[1]);
 
$user_pattern = "/\@([a-zA-z0-9_]+)/";
$post_content = preg_replace($user_pattern, '<a href="http://twitter.com/${1}">@${1}</a>', $post_content );
$post_content = preg_replace($tag_pattern, '<a href="http://twitter.com/search?q=#${1}">#${1}#</a>', $post_content);
