The gmp_random_bits() function is an inbuilt function in PHP which generates a random number. The random number will thus be between the range 0 and (2 * bits) – 1. Here bits must be greater than 0, and the maximum value of bits is restricted by available memory. Here GMP refers (GNU Multiple Precision) which is for large numbers.
GMP gmp_random_bits ( int $bits )
Parameters : The above function accepts a single parameter as mentioned above and described below :
- $bits : IT accepts only one parameter This parameter can be a GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and later, or we are also allowed to pass a numeric string provided that it is possible to convert that string to a number.
Return Value : The function returns a random GMP number.
Input : bits = 3 Output : 3 Input : bits = 5 Output : 15 Note: Output will vary every time on execution
