wp-super-cache页面不相符!时间戳有差异或者不存在错误解决

服务器升级PHP5.6后,WP-SUPER-CACHE报错”cURL error 35: Cannot communicate securelibrary: invalid arguments.“,原因是PHP5.6升级后php–curl模块默认使用NSS库的curl,导致wpsupercache无法正常访问本站。

关于给wordpress的tag加上nofollow属性

偶尔在google上看了一下自己站点的收录信息:简直一塌糊涂啊.标签页,page页,图像页等等全都给收录进去了,以前还觉得收录越多越好,都是年轻的时候犯的大错,居然要长大的自己来承担,所以今天给tag做了小小的优化,为A链接添加nofollow属性.

Windows网卡叠加

以前经常在网上找网卡叠加的小软件,找过很多个,有的用不来有的没效果,偶尔找到一个能用的批处理,于是根据这个脚本自己用python写了一个修改路由表的方案,这样一来下次就不用在网上找来找去了,简单实用(水平有限,还请在座各位多多指教)。 Windows网卡叠加 - 1 废话不多说直接贴代码,送给需要的人

PHP防注入方法

(1)mysql_real_escape_string — 转义 SQL 语句中使用的字符串中的特殊字符,并考虑到连接的当前字符集
使用方法如下:

$sql = "select count(*) as ctr from users where username
='".mysql_real_escape_string($username)."' and 
password='". mysql_real_escape_string($pw)."' limit 1";

使用mysql_real_escape_string()作为用户输入的包装器,就可以避免用户输入中的任何恶意 SQL 注入。
(2) 打开magic_quotes_gpc来防止SQL注入
php.ini中有一个设置:magic_quotes_gpc = Off这个默认是关闭的,如果它打开后将自动把用户提交对sql的查询进行转换,比如把 ‘ 转为 \’等,对于防止sql注射有重大作用。如果magic_quotes_gpc=Off,则使用addslashes()函数
