[SOLVED] Is this technical possible?

[willdk]

Everybody knows how to redirect page A to page B. But can you control how many times the redirect can be used?

 

Example;

100 visitors visit page A, and you "tell" the script to only redirect 50 to page B. 51 through xxx is redirected to another location.

I see no reason why it wouldn't be possible.

I see no reason why it wouldn't be possible.

I'm very curious HOW you make something like this, how do you START. I have searched for existing scripts, but there aren't.

 

If someone visits a redirect, his visit get lost. So you can't count this.

And if you CAN count this, how do you tell the script to stop redirect the visitors to page B.

 

I need a plan, because I have no idea.

You could store the number of users redirected in a flat-file.

 

$num = file_get_contents('counter.txt');
file_put_contents('counter.txt', $num + 1);
if($num <= 50)
     header('Location: a.html');
else
     header('Location: b.html');

One of the ways would be to store the number of visits into a file.

Script would work like this (psudocode)

 

read number of visits from file
(if > 50) {
redirect to B 
}else {
increase number of visits by 1 and save to file
redirect to A
}

     header('Location: b.html');

 

Perfect!

@AlexWD and Mchl

Thank you very much for explaining this to me. I didn't know it would be that simple. I actually expected a "No! Not possible..."
