To learn more about these functions click here. Once we understand how we utilize these functions, our task becomes pretty simple.

So if you want to generate string of a fixed length, you can either truncate the generated string or concatenate with another string, based on the requirement. Approach 3: Using uniqid() function. The uniqid( ) function in PHP is an inbuilt function which is used to generate a unique ID based on the current time in microseconds (micro time). By default, it returns a 13 character long unique string. Program: php

These functions are not cryptographically secure random generators. So it is advised that if the degree of randomness affect the security of an application, these methods should be avoided. Approach 4: Using random_bytes() function. (Cryptographically Secure) The random_bytes() function generates cryptographically secure pseudo-random bytes, which can later be converted to hexadecimal format using bin2hex() function.
