How can I create a loop or limit for random number generation? I need 30 random numbers from (0,100).
I know I can use rand(0,100), for general generation of numbers. But I need to make this happen 30 times before I can sort out the data.
Repetition of numbers is NO issue, but I also need to sort the values into x<50 and x>50. Any idea how I can pull numbers from the array into 2 separate groups once generated?
Try this:
$lessFifty = array(); // Array to hold less than fifty numbers
$moreFifty = array(); // Array to hold more than fifty numbers
for ($i = 1; $i<=30; $i++) {
$number = rand(0, 100); // Variable $number holds random number
// Conditional statements
if ($number < 50 ) { // Check if value is less than fifty
$lessFifty[] = $number; // Add number to this array
} else { // Check if value is greater than fifty
$moreFifty[] = $number; // Add number to this array
}
}
// Display numbers in arrays
print_r($lessFifty);
print_r($moreFifty);
The for loop will will run the rand() function 30 times and insert each random number generated into the array $randomNum.
You can also use the while or do while loop to do the same action. It is up to you.
$lessFifty[0] where $lessFifty is the array and [0] the index of the value in the array.
