![]() ![]() These functions are explained with sample examples. In this article, we learned about various functions used to generate a random number in PHP. mt_rand(100,999) įloating-point numbers represent a number with decimals that are of the type float. rand(1000,9999) Įcho 'Following are the different random values using mt_rand() ' Įcho ' Using mt_rand()->'. rand(0,9) Įcho 'Any random number within the range from 1000 to 9999 ->'. In the following example we have used rand(),rand(min,max) and mt_rand().Įcho 'Following are the different random values within a range ' Įcho ' Any random number within the range from 0 to 9-> '. The return type is an integer.Įcho ' Range : 1 to 100 -> '. The default value of min is 0 and the default value of max is the given highest value. ![]() Where min is optional value and denotes the lowest number and max is optional value and denotes the highest number. The return type of the function is always an integer.Įcho ' Range : 1 to 100 -> '. ![]() Where min is the optional minimum value and denotes the lowest number value and max is the optional maximum value and denotes the highest numerical value.Īlso, min has a default value of zero and max has a default value of getrandmax() function value. This function provides the range to the rand() function. rand() FunctionĮxample: '.'Following are the different random values' We will learn the syntax followed by the examples of each type of function mentioned. mt_srand(seed): This function is similar to srand() function and this function seeds the random number generator with the given seed value.srand(seed) function: This function seeds the random number generator with the given seed value if not given this function seeds with a random number.Here again mt stands for Mersenne Twister which is an algorithm for generating random numbers. mt_getrandmax() function: It is similar to getrandmax() function and it also returns the largest or maximum possible random number.getrandmax() function: There are no parameters defined for this function and as the name suggests it returns the largest or maximum possible random number. ![]() It is fast, efficient and provides high-quality integers. It is an advanced form of older random number generator. It was the first pseudo-random number generator. It generates a pseudo-random number like the rand() function does. The mt_rand() function is a random number generator and returns an integer value. mt in mt_rand() stands for Mersenne Twister.
