The gmp_random_range() is an inbuilt function in PHP which generates a random number.The random number thus generated lies between range min to max. Here GMP refers to (GNU Multiple Precision) which is for large numbers.
Syntax:
gmp_random_range ( GMP $min, GMP $max )
Parameters: The function accepts two parameters, GMP $min number representing lower bound for the random number and GMP $max number to represent the upper bound of the random number. This parameter can be a GMP object in PHP version 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 in the range $min-$max.
Examples:
Input : lower bound=0, upper bound =100
Output : 25
Input : lower bound=-100, upper bound=-10
Output : -23
Note:Output will vary every time on execution
Below programs illustrate the use of gmp_random_range() function:
Program 1: The program below demonstrates the working of gmp_random_range() function when numeric strings are passed as arguments.
<?php
$min = "-200" ;
$max = "-100" ;
$rand = gmp_random_range( $min , $max );
echo $rand ;
?>
|
Output:
-165
Program 2: The program below demonstrates the working of gmp_random_range() when GMP number is passed as an argument.
<?php
$min = gmp_init( "1000" , 2);
$max = gmp_init( "1000000" , 2);
$rand = gmp_random_range( $min , $max );
echo gmp_strval( $rand ) . "\n" ;
?>
|
Output:
30
