Many PHP developers will use this md() encryption function, but some friends may not know the reference. Today we will take a look at the parameters of the md5() function.

Grammar
md5(string,raw)

md5() function calculates the MD5 hash of a string


string required. Specifies the string to be calculated

charlist

Optional. Specify hexadecimal or binary output format:
TRUE - raw 16 character binary format
FALSE - Default. 32 character hexadecimal number
Note: This parameter was added in PHP 5.0.

The code is as follows
 代码如下 复制代码

$str ="123456";
echo 'md5 16位'.md5($str,true);

//输出乱码

//如果你想得到php5中md5( "abc ", true)这样的返回值，那么可以：
function bin_md5($val) {
return pack( "H32 ",md5($val));
}

echo '
md5 32位'.md5($str);

?>
Copy code
$str ="123456";

echo 'md5 16-bit'.md5($str,true);

//If you want to get the return value of md5("abc", true) in php5, then you can: function bin_md5($val) { Return pack( "H32 ",md5($val)); } echo '
md5 32-bit'.md5($str); //10adc3949ba59abbe56e057f20f883e ?>
