[Haggis]

I am making a stats package and i want to be able to if an update is available let the user know

 

how can i use php to check to see if there is an update

well, you could make a txt file, that has the current version number. and every time an administrator of this package logs into their administrative account, it goes to your web site to check this txt file. In the php, you would check and see what the current version of the package is, and if it is older, that means that theirs is out of date, then you just have them go to your site to download the new package.

ok so for example

 

in my script have

 

$ver = 1;

 

 

then in the text file have 1

 

then when update it due change it to 1.2

 

then when the script checks if $ver does not match 1.2 it would pop up a message

 

yeah?

[The Little Guy]

yeah.

 

so maybe something like this:

 

$ver = 1;
/*
Replace this block with getting the newest version not all servers support fopen from other sites,
so cURL may be the best way to get the newest version.
*/
$newestV = '1.2'; // this won't always be 1.2, depends on what the text file is
if($newestV > $ver){
     echo'<script>alert(\'There is a newer version avalible (v'.$newestV.')\');</script>';
}

That is exactly how I do it as well.
