这两天升级MYSQL后，当访问系统权限表时，出警告，说需要使用mysql_fix_privilege_tables来升级。查了一下网上的信息，有很多人都在问这个脚本文件在哪里啊？等等。其实这个脚本本身就是命令了。可以直接执行。
这个命令默认使用root用户，但是有很多系统root帐号已经被删除了。就要使用参数了。具体的如下：
我不知道别人的能不能成功，总之我运行上面的命令总是报错。
后来研究了一下手册，只要用下面的命令就可以轻松搞定。还让我浪费2小时。希望大家以后不会犯我同样的错误了。

This script updates all the mysql privilege tables to be usable by
the current version of MySQL
Got a failure from command:
cat /usr/local/share/mysql/mysql_fix_privilege_tables.sql | /usr/local/bin/mysql --no-defaults --force --user=root --host=localhost --database=mysql
Please check the above output and try again.
Running the script with the --verbose option may give you some information
of what went wrong.
If you get an 'Access denied' error, you should run this script again and
give the MySQL root user password as an argument with the --password= option

mhash是php hash加密算法很强大的扩展，但是php5.3.0以后就不包含这个程序包了，需要自己去下载，http://sourceforge.net/projects/mhash。
php5.2.0默认不挂载，所以就需要自己手动去挂，windows版本安装比较容易，只要extension_dir = "d:\AppServ\php5\ext"设置好，并且将;extension=php_mhash.dll的分号去掉即可。
可是很多时候发现，还是不能挂载，日志中报错，
查找环境变量发现PATH设置也是正常的，可就是不能加载php_mhash.dll，碰到这样的问题解决办法如下：
由此得到的启发就是，如果在windows下动态链接模块加载不了的，请将相关的libxxx.dll复制到C:\WINDOWS\system32下去即可。

这个发现是由一个问题引发出来的。如何根据字符串的位置，把字符串该位置的字符取出来？一般就是用substr函数取该位置长度为1的字符出来就实现了，可是我们还有更加简便的办法，请看下面：
这样上面的问题就太容易解决了，把位置减1，再带入数组即可。哈哈，方便啊！
引用
$str = "abc";
echo $str[1];
结果会是 b。
这样其实在php里字符串$str，本身就是数组$str。
$str = "abc";
等同于
$str[0] = "a";
$str[1] = "b";
$str[2] = "c";
echo $str[1];
结果会是 b。

我们曾经或多或少都会碰到过MD5密码文件校验之类的。知道MD5是一种不可逆的加密算法。其实MD5只是hash（哈希）中的一种运算规则。那么除了MD5还有多少种呢？请看下面：
哇！原来hash的运算规则有这么多啊，有好多都是我们所不熟悉的，那么当我们看到一段不规则的字符串的时候，我们如何推断大概是用哪种加密算法生成的呢？请看我们的例子：
希望上面的资料能够给大家一些帮助
