How to Generate String Unique Number in PHP

In php have a unique id function to generate unique id, but this system can’t given proper result all time

. This is my personal observation. If you use md5 and unique id both hopefully you overcome this situation.

Example:

md5 (uniqid());

Another way use random value to make unique id actually unique.

Example:

uniqid (rand (1,10000));

First option i preferer more.

I hope you get solution. Happy coding.
