问题贴,高手,新手,求职的,招聘的都进来看下

先问招聘的吧,

招聘信息好像都是说,要精通PHP,MYSQL,LINUX,AJAX,CSS+DIV之类的,请问精通要怎么定义?????

MYSQL,LINUX,APACHE虽然跟PHP是黄金组合,但偶想说,精通数据库的那是DBA,精通LINUX的那是系统工程师,CSS+DIV好像是页面布局用吧,

初级,中级,高级PHPER要怎么区分?他们的区别是什么?

再来问下所谓的高手,,,

究竟什么样才是高手呢?会两个框架?弄个类?

除了 if else for 请while foreach 请 问您还会什么?会框架? 那是不是应该称您为框架大师呢?

个人见解:

编程都是相通的,不管是PHP/JAVA/C/C++/PERL/PYTHON 只是语法不同.....

框架:可以提高开发效率.使代码重用性高.同时也使也使你的大脑变的简单.因为所做的一切都是别人为你准备好的,你所要做的就是调用,,,,

做PHP不是长久之计,可以把PHP视为你编程的入门语言(因为简单),如果有机会还是要转向C++/JAVA 之类的当然PERL/PYTHON也是不错的选择.[这点只是个人的想法,并没有贬低PHP的意思,如果让我做WEB的话还决对是选择PHP] .

有位哥们说以下代码应对一般的面试足已:

有什么过人之处吗?没有,,,

高手们,,请在下面贴出你们认为有技术含量的代码,让小弟拜读学习一下,,,不胜感激...

补发: 上面的代码数据库链接用到createDB()函数.在这里补发上

复制PHP内容到剪贴板

PHP代码:

functioncreateDB() { global$dbhost,$dbuser,$dbname,$dbpw,$pconnect,$database,$charset,$dbcharset; if(PHP_VERSION<'5.0'||function_exists('pdo_drivers')||!in_array($database,pdo_drivers())) { require_onceCMS_ROOT.'require/'.$database.'.class.php'; $db=&newDB($dbhost,$dbuser,$dbpw,$dbname,$pconnect); } else { require_onceCMS_ROOT.'require/pdo.class.php'; $db=&newDB($dbhost,$dbuser,$dbpw,$dbname,$pconnect); } return$db; }

这个函数返回一个数据库的句柄,如果支持PDO就用PDO,不支持DPO用默认的在 require 目录下的 $database.class.php 数据库类

做好MYSQL的了,现在正在做SQLite 的类..

PDO.CLASS.PHP
