TUTORIAL - Generate random numbers with rand ()

Posted by admin On March - 25-2009

Hello everyone! I'll tell you about the rand () function, PHP used to generate random values.
This function is simple but can be very useful in, because with it we can create a system of rotating banners, make a script to generate a key for the euro millions, we can also use it to reduce duplication of files (by assigning a name to a file of the genus axfgafasf21fdsf.jpg) and so on.
