Website wide function

D_tunisia

I know you can do this with C++ so I'm sure there must be a way to do it with PHP -- I just don't know how!

I have some code which allows my users to login to my website. At the moment I am doing it in one of two ways. Firstly I just place the code directly into the page and another way is I call another page (using virtual ("page.php")).

Is there a way to use something like a function call? I have a file which in included on each page. I guess the easiest way would be to add the code to there and then call it from ny required page. But how could I do this, and is there an easier way?

Thanks.

make a function called something like validate_user(). Put that function in a file called, for instance, functions-user.inc.php. I recommend putting that file in a directory called include. Then, in any script that needs that function, just do:

require_once('include/functions-user.inc.php');

(you may have change the path to something like /path/to/my/include/dir/functions-user.inc.php if you're not in the directory that contains the 'include' directory.)

Thanks!

So where I put the require_once('include/functions-user.inc.php'); will that call the full code or will I need to activate it in some way?

change your login.php into a function something like
login.php

function checklogin($username,$password)
{
//Your original login.php
..
.
.
}

include this in pages where you want to use this function. Say u want to use ur login script in something.php..

something.php

include("login.php")
checklogin($username,$password);

Is this wat u asking for?

require(), require_once(), include(), or include_once() will all act as if you took the code in the file you're including and copied it right into your script, so yes, it will "call the full code".

require() and require_once() will cause your script to exit if the file is not found or isn't readable for some reason (which is probably what you want for user validation functions). I recommend using require_once() unless you have a reason not to, because if you accidentally include the same file twice, you will get errors.

include() and include_once() act the same way but won't cause your script to exit if the files aren't found.
