Something simple and functional is to use timestamp information
$token = microtime();
It will return something like this
0.13287600 1460718460
If you do not want the space character then you can also generate:
$token = microtime(true);
Return something like: 1460718491.9867
Of course, if this uuid / token is publicly accessible, it is recommended that you encrypt it at least to prevent anyone from understanding how the token is generated. In this example, using timestamp any programmer can assume that the format is a timestamp and can thus be able to do a token hijack. So if you use a very obvious sequence, encrypt it.
$token = hash('sha256', microtime(true));
//gera algo como '6d20018cf7023becaf77a2e0dc5d4034894aebdde9febb093f83dbcc3744bce0'
