$cryptkey = $keya. MD5 ($keya. $KEYC); What do you mean, how to deal with it?

$cryptkey = $keya. MD5 ($keya. $KEYC); What do you mean?
$cryptkey = $keya. MD5 ($keya. $KEYC); What do you mean?
Rt

------Solution--------------------
Which is a MD5 encryption.

------Solution--------------------
Embarrassing ~
$cryptkey = $keya. MD5 ($keya. $KEYC);
First connect the $keya to the $KEYC. Then do MD5 encryption, and then use $keya to connect with this encryption result, save as the last encryption result $cryptkey.
------Solution--------------------
Give me an example.
$keya = ' 12 '
$KEYC = ' 3 '
MD5 ($keya. $KEYC) =md5 (' 12 '. ') 3 ') =202cb962ac59075b964b07152d234b70
$keya. MD5 ($keya. $KEYC) =12202cb962ac59075b964b07152d234b70
So
$cryptkey = $keya. MD5 ($keya. $KEYC) =12202cb962ac59075b964b07152d234b70

The 2 floor is right, haha.
