Save values to file using php

Hi all,

How can I click on a button and save a string to a file in php please?

For example:MainPage ... contains a button or link ...

I click on it and it saves: eg: $var1 = 'somestring';

Then, if I click another button for $var1 .. it would replace 'something' with 'somethingElse'

Very Important: I don't want the page to reload everytime a press a button to save.

Can anyone help please?

Thanks
PHP

File_put_contents();
But that can't run at the press of a button. You would have to make another page that has this function, and use JavaScript to make an Ajax call to that page that saves the file.

hmm....

Tried this:

<a href="#" onclick="<?php echo file_put_contents("test.txt","Hello World. Testing!"); ?>">Save Me</a>

and it saves the data and creates the file even if I don't click on the link :o/

It would be perfect if I could control that.

Right. Php is serverside. It will "do" that code when the page loads. If you want to do anything after page load, you have to do it in js. The js can call another file onclick though. So put the save code in a different file. Let's call it save.php. It can take get or post vars for filename and data.
Call save.php with js. That way you don't leave the page you are on.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
