PHP开发的一些注意点总结_php技巧
现在标配的系统是 Linux + Nginx + PHP + MySQL ,这样的配置越来越多的大公司在用的了说到配置不同的是一个公司的规约,比如说挂载一般分为2个盘, / 下面划分为系统用的分区10G 足够 剩余空间划给/home的了.这点我感觉比较好的,原来我划的太多的了,其次是对于系统的安全登陆,现在小公司或者个人的做法是通过网络,直接使用帐号或者密码直接登陆而相对大公司的做法是,先登陆relay中转服务器,然后通过中转服务器登陆到目标服务器,这样帐号会被记录,安全性比较高,现在一般用了TOKEN,RSASecurID进行密码登陆,提高了整体的安全性了.
PHP调用shell命令
在之前没有使用到php调用到shell来执行一些额外的任务,现在会经常用到的了,这样就可以做脚本之外的事情了,这点感觉比较方便
编码习惯上对于编码习惯,每个公司和团队往往使用的都不同,特别是编程IDE的不同导致了编码规范的不同而约定也就不同的了,不过对于整体的习惯经过团队全体人员的决议,就定下来了,这点在原来的小公司没有要求的很严格,现在也是这样的,看来这个和团队文化还是有很大关系的了,这点团队的人相处久了,自然就熟悉的了.
函数返回值
一般对于获取失败的返回值都返回的是false,对于出现的多种情况,返回int的数值,如果是数据则返回的是array或者其他,对于现在的函数由于memcache的使用,现在用了很多的函数内的cache操作,返回值也是先从cache取得,如果没有在到数据库中取得,然后写入cache,然后返回数据
对于处理数据写入原来的写法是在$_POST && $_GET 过来的数据,然后进行addslashes处理,现在的做法是直接接收,然后进行数据判断是否符合要求,然后在拼接sql,然后对sql语句进行mysql_escape_string处理,然后在读出数据的时候,使用htmlspecialchars进行处理,这样显示就没有问题的了.
锁机制的PHP实现
前段时间写过一篇文章并发下常见的加锁及锁的PHP具体实现
关于队列的分发问题
使用了MQ进行Memcache数据的分发,这点还没弄明白,具体的实现,得在请教的了
关于PHP的错误级别的认识
原来对于错误级别,在开发的时候用的都是比较轻的E_ALL | E_STRICT 现在换成了E_ALL & ~E_STRICT 养成变量定义的好习惯,使用时候初始化是比较必要的.
对于防止用户发表违法信息及广告的控制及用户行为频率的控制
对于用户发布的广告,违法信息都用SPAM系统进行了控制,防止出现问题,对于用户行为进行了限制,防止用户过多的控制资源,对于系统中的变量不能使用自增的唯一ID,需要进行加密处理,返回系统信息被其他人获得.包括用户ID,数据信息ID的加密处理
