带有运算符+的md5哈希

Question

For an api, I need to get md5(md5(text)+timeUNIX) so I made this in php :

md5((md5(123456789)+1498740101);

But it returns ceac5623c9b370f9581d4f61764c5b6d and I know that this hash with this time and this text is dbbc59e0b318fb9a4e64fc175644bf92 .

Does someone know? is there any issues/problems with the operator + in md5's function ?

Answer 1

This is the answer to your question md5((md5(123456789).(1498740101))); in your example you calculate not concantinate.
