Code to rotate easily between adsense and ypn

A few webmasters have recently been talking about rotating google and yahoo ads on the same page. I wrote a VERY simple php script to do this. You just need 2 text files. One of them called adsense.txt which contains your adsense code and the other called YPN.txt which contains your YPN code. The reason you need to include the txt files is because if you put the code directly into the script you would have to excape the “’s and therefore violate TOS by altering the code. Just to be safe the example below shows you how to do it with includes.


< ?php
$number=mt_rand(1, 2);

if ($number=="1") {

include "adsense.txt"; #include the text file with adsense code

}
else

{
include "YPN.txt"; #include the text file with ypn code

}
?>

thats it!

    shoe shoe, would it be too much trouble asking on how can we make it with 3 or more included txts ?.

    thanks in advance :)

    That code is not good:
    if ($number==”1″) {
    should be:
    if ($number==1) {

    It ain’t no string…

    I’m very, very impressed that this sort of work is being done; Web Design is getting stagnant with people using just styled
    block-level elements to produce artwork. The incorporation of SVG into sites excites me a lot.
    How long do you expect it will take for this sort of technology to be widespread?
    Obviously you can only speak about WebKit realistically, but if it’s going to take ten years for IE Win to gain (full) support,
    we can’t design with it.
    I’m amused by the “Becoming more important” line in the first paragraph. This has been a HUGE problem for years –
    ever since HTML-2.0 was introduced to be more of a layout language and less of a markup language. For an example,
    you just have to look at this site. adults-dot.com Why is all the text
    crammed over on the left side of the page with a big blank space on the right side?
    Why is the default font tiny and unreadable? Fortunately most browsers now let you override the latter problem.

    Hi All. Help me please with my MSIE!
    In my title bar instead of “Microsoft Internet Explorer” a title appears as an advertisement about a site i visited
    “visit http://www.site353535.com and register for free”. What can I do to restore my browser? And why on this site:
    http://singles-sex-clubs.swingersdate.net (meet single woman)
    I constantly see “cannot resolve host name”? Waiting for your reply.

    Looks interesting. Thanks for sharing.

    I have an AdRotator plugin for WordPress for quite sometime which allows you to randomly choose between several ads/provider. You you could use it to rotate between say YPN,AdSense, Chitika and other. All it requires from you is adding the ad codes to a text file.

    -meta http-equiv=”Pragma” content=”no-cache”-
    – Pragma content set to no-cache tells the browser not to cache the page
    This may or may not work in IE –
    or
    -meta http-equiv=”expires” content=”0″-
    – Setting the page to expire at 0 means the page is immediately expired
    Any vales less then one will set the page to expire some time in past and
    not be cached. This may not work with Navigator –

    I could not post the actual code here because of posting limitations. You can find no cache code via a google search.

    This does not seem to work for me. Browser caching always seems to show the wrong ad!

    Nice simple way to rotate the Adsense and Yahoo YPN code on the same page of your site! Thanks, much.

  16. Steve

    This is one way to rotate ads but it is also random, therefore you do not know how many Y ads vs G ads are being shown. You could also rotate using any “drop”. Set a cookie for that user and serve ads based on that users cookie, you could drop the current var into a DB and use it globally, each client getting whichever is next Y or G… I prefer the cookie as it should be more measureable as the split is a true 50/50

    Hope that makes sense… it’s late.

    This is a great idea and a great piece of code, thanks!
