php md5下16位和32位的实现代码

复制代码

创新互联是一家专业提供长乐企业网站建设,专注与做网站、网站设计、H5页面制作、小程序制作等业务。10年已为长乐众多企业、政府机构等服务。创新互联专业网络公司优惠进行中。

代码如下:

?php

echo substr(md5("admin"),8,16); // 16位MD5加密

echo "hr";

echo md5("admin"); // 32位MD5加密

?

16位的MD5加密用substr函数截取了字符得到实现....

不想深入研究了 :) 要把脑力放到其他关键的地方~~

今天做了个php链接mssql数据库,数据库中的表中字段使用MD5十六加密的。但是php中的MD5默认是32位,导致登录程序没办法使用md5加密跟表中字段匹配,在网上一搜也有不少人有这方面的困惑,后来找到一个解决办法,是正确的,就记录下来。

使用substr函数截取:

substr(md5("admin"),8,16);

//

16位MD5加密

md5("admin");

//

32位MD5加密

经过脚本之家测试结果如下:

我们以asp的几个md5后的结果比较

附:如果遇到MD5加密文件,而又不知道的密码的,请在数据库中换上这组加密的数据。

admin---16位加密---7a57a5a743894a0e

admin---32位加密---21232f297a57a5a743894a0e4a801fc3

admin---40位加密---7a57a5a743894a0e4a801fc343894a0e4a801fc3

substr(md5("admin"),8,16);

//

16位MD5加密

正是上面的32为从第8个字符开始的16个字符。所以大家不用考虑唯一性的问题。本身就是正确的。网上有人说php5支持

复制代码

代码如下:

echo

md5("admin",true);//返回16位,不过这是在PHP5里才有。

经测试输出的结果是乱码,如果大家有什么好的代码,可以分享下。

编写一个php文件,使之能获取到js中的下载地址

e4a怎么取数据库的表中指定列的内容

1、建立一个指定内容的mysql数据库,写几个字段,再建立一个中间件连接数据库,编写E4A程序连接该数据库。

2、在数据库面板输入指定的英文包名和应用名称内容即可,然后该工程会被保存在E4A安装目录的projects文件夹中,用e4a读取数据库表中指定列的内容即可。

E4A数据库数组怎么执行

1。先将从数据库中取出的内容,按所属字段赋值给字符串变量(字符串变量的个数等于您取出内容包含的字段数目;

2.定义数组;

3。根据字符串变量的个数为循环语句设置循环条件;

4.执行循环语句,为数组的每个成员赋值。

E4A图片二进制存取到数据库什么编写代码?

//图片转成二进制

public byte[] getBytes(string filePath)

{

System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Open);

byte[] imgData = new byte[fs.Length];

fs.Read(imgData, 0, (int)fs.Length);

return imgData;

}

//二进制转成图片

private System.Drawing.Image convertByteToImg(byte[] imgData)

{

System.IO.MemoryStream ms = new System.IO.MemoryStream(imgData);

System.Drawing.Image img = System.Drawing.Image.FromStream(ms);

return img;

}
