PHP | gmp_random() Function
The gmp_random() function is an inbuilt function in PHP which generates a random number. The range of random number will be in between zero and the number of bits per limb ( A limb is an internal GMP mechanism. The number of bits in a limb is not static and it can vary from system to system. Usually, the number of bits in a limb is either 16 or 32 but this is not always true. ) multiplied by limiter .The number generated depends on the limiter i.e. if the limiter is negative then the number generated will also be negative.
GMP gmp_random ( int $limiter )
Parameters: The gmp_random() function accepts a single parameter as shown above and explained below:
- $limiter : It is the only required parameter accepted by the gmp_random() function. This parameter sets the limiter value. This parameter can be a GMP resource in PHP 5.5 or earlier, a GMP object in PHP version 5.6 and later, or also allowed to pass a numeric string provided that it is possible to convert that string to a number.
Return Value: This function returns a random number between zero and the number of bits per limb as explained above.
