Just a quick snippet which will help you to create a random number in a specific range, using PHP. PHP has a built in rand(); fuction which allows you to do this with ease. See the example below :
PHP Random Function :
Example :
The code shown above will create a random number between 1 (which is the minimum) and 999 (which is the maximum).
You can make the [min] and [max] values of this function dynamic, simply by replacing the digits with your variables. You can also assign this function to a variable itself and ouput the results if needed. See the simple example below :
I wouldn't say that this function is really used that often, but it definitely comes in handy from time to time. Enjoy!
