Time() function in PHP

Question

I just wanted to ask, since I'm coding a script, and I'm using time() as a salt for what I am doing.

Now what's happening is I'm salting the data sent from server 1, to server 2. Server 2 checks to see if the data = submitted_data + time() matches exactly. And I wanted to know, since my script will be used on different servers, will the time() function return the same value (if they're located in different parts of the world?)

A code example from the client is:

if($return == md5("true" . time()))

And a code example, where if the data that's submitted correctly, will return this:

echo md5('true' . time());

Both are on different servers in different parts of the world, but I wanted to know if using the time() will mess up the way my system's going to work..?

Answer 1

Why don't you try following :

echo date("Y-m-d H:i") echo strtotime(date("Y-m-d H:i"));

Value of strtotime(date("Y-m-d H:i")); would not change until you pass the next minute OR you can remove "i" based on your requirement.

Hope that helps.
