How to insert codes in a php file?

A friend of mine inserted banners and google ads directly in the php files so he managed to place google ads in very unusual places.
I tried to do that too but it gave me some errors.
How exactly do you do it?
Is there some trick that I don't know?

Am not clear about your question. But am giving some general tips about .php and HTML with the files.


The execution of a php files done in part by parts. Those parts of a php file enclosed under <?php .... ?> is going to execute. So you can put the normal HTML codes on the .php files with out restriction outside the php code.

So, I'll open, for example, the theme.php file and add the new html or javascript code after the ?> part? or before the <? part ?
But won't this affect the php file?

Yes...

That parts remains as the same html file..

Im going to explain here the processing of a PHP file when clients request it. -

On the invocation of a php file request, the server settings invokes the php parser to fetch that file and interpret the full file line by line. They only compiles those parts enclosed within <? ---- ?> the other parts directly send to the clients with our executing that part. So the client gets the all parts outside <? ..... ?> intact, without any change.

So you can put any thing out side the PHP tags.

But it didn't work for me.
I put the code outside the <? part and nothing :|

Does google adsense generate a php code too, not just a html one?

Are you using the same code given by adsense?.. Just put the code in the file as HTML code, nothing else. Also don't try to put code with the help of advanced HTML editors like frontpage or dreamviewer. Since we are dealing with page codes, they can generate unwanted codes for the page, which generates errors. Use notepad for coding.

Very simple..

Open your notepad. Name the file as "adsense.php".

Then put the adsense code int the file as content and save it. Then upload it into your site. Very simple. That is not though and it is the simplest part. The main advantage of using a separate file for ads is that you can change the entire site's ads by changing a simple file.
