Using the rand() function: The rand() function generates a pseudo-random number between a given range, or between 0 and the default maximum (getgrandmax()), which is system dependent.Syntax:
`int rand (\$min, \$max) `
Parameters:the rand() function takes two optional parameters as above and described below.
• \$min: is an optional parameter used to set the lower limit for the random number. The default min is 0.
• \$max:This is an optional parameter used to set an upper limit for the random number. The default is max - this is the return value of getgrandmax(), which is system dependent (for Windows it is 32767).
Program 1:PHP program to generate a random number using the rand function().``` // PHP program for generating a random number // within the specified range // Generate random numbers without a range // the rand() function returns a random number \$num1 = rand(); echo " Random number: " . \$num1 . "" ; // Generate random numbers in a given range \$num2 = rand (7, 100); echo "Random number in range (7, 100):" , \$num2 ; ?> Exit:Random number: 77551982 Random number in range (7, 100): 37 Note.The rand() function - it is a pseudo-random function which means that it takes a seed from the machine and generates a number according to it. Thus, the method for generating numbers is not completely random. This can be tracked to a certain extent. So it is not cryptographically secure. It is not used for cryptography where randomization is very important. Use the random_int() function to generate a cryptographically secure random number. Using the random_int() function: random_int() is used to generate cryptographically secure random numbers. These numbers can be used for objective results. CryptGenRandom() function on Windows and getrandom (2) system call on Linux to generate a random number.Syntax:int random_int (\$min, \$max) Parameters:The random_int() function takes two parameters as above and described below. \$min: contains the lower limit of the random number. \$max:contains the upper limit of the random number. Program 2: Generate random numbers in a range using the random_int() function. // PHP program for generating a random number // in a given range // Generate random numbers in a given range // using the random_int() function \$num1 = random_int (35 , 100); echo " Random number in range (35, 100): " . \$num1 . "" ; // Random number in the range (10, 30) \$num2 = random_int (10, 30); echo " Random number in range (10, 30): " . \$num2 ; ?> Exit:Random number in range (35, 100): 93 Random number in range (10, 30): 28 👻 Read also: what is the best laptop for engineering students?

I was stuck with PHP program to generate a random number in a given range (min, max) for some hours, finally got it done 🤗. I just hope that will not emerge anymore Chen Gonzalez Moscow | 2023-03-22 Simply put and clear. Thank you for sharing. PHP program to generate a random number in a given range (min, max) and other issues with code Python module was always my weak point 😁. I just hope that will not emerge anymore Anna Zelotti London | 2023-03-22 StackOverflow is always a bit confusing 😭 PHP program to generate a random number in a given range (min, max) is not the only problem I encountered. Will use it in my bachelor thesis ```
