Hello all, I'm pleased to be a member of this great forum. After searching google for a programming forum, Codecall seemed to be the best I've come across in my opinion.

I'm looking help on loading random numbers.
I'm trying to load one random number and make it appear on screen with a medium sized font and I want it to load from a list of about 40,000 numbers in a text file. The numbers are ALL 5 digits long. I want it to be a totally different number everytime someone loads the page.

I'm not very good at writing new code, I've learned a little bit by manipulating a little bit of Wordpress code. As a matter of fact I will be trying to implement the above code in Wordpress.

Thank you guys for all your help, and for starting this great forum. :D:pinguin:


Edit: What do you guys think would be better to load them from a txt file or from a Database?

My opinion, text file is better. There are all integer type and how many numbers each line has?

The function file() will return an array with entries containing each line of the specified file, of which you can print a random entry using the various available functions.

For example you can select a random entry with $lines[array_rand($lines)] or $array[mt_rand(0, $linecount-1)]

PHP: file - Manual
PHP: array_rand - Manual

@toto_7: Each line would have just one 5 digit number.

There will be a total of around 40,000 numbers.

Alexander came before me :) .. said what i will say

I'm sorry to ask such a noobish question, but seeing as how I have no clue how to code in PHP (I'm good at editing it or deleting certain code), how would I put the code together to make it so it displays a number like this:


Your (site) lottery code is: 99999 <--- example

Where the "99999" is picked out randomly from the text file I uploaded.

Thanks for the info guys, I really appreciate it. I'm not asking to be spoonfed, but if you can point me into the right direct it would be a great help :D.

I have given you simple functions of which can achieve this intended result in one or two lines, feel free to look at the example usage of file().
