calling individual functions on a remote php page

[tolkienarda]

hi all

i am building a small private school management program and i use alot of the same loops, update statements, and whatnot and i would like to put them all into one php file divided into their own functions. i was just wondering if it is possible to call an individual function on a remote php page.

thanks
eric

Of course you can,

Create all of the functions on a separate page ie function.php

then of course you list your functions on that page

function dbconnect()
{
        global $db, $t_global;
        $db_con = @MYSQL_CONNECT($db['server'],$db['user'],$db['passwortd]) or die ($t_global['query_false']);
        $db_check = @MYSQL_SELECT_DB($db['name']);
}

blah, blah, blah

The in the actual php page that you are using you will need to include the function page

<?
                include "function.php";
?>

And to call the function in your php page you will need to do like the following

$connect = dbconnect();

Hope the above helps and Good Luck!

Small correction: in order to use this command[php]$connect = dbconnect();[/php] the dbconnect function must return a value, otherwise you cannot assign it to the $connect variable.

Hi Ronald,

I don't quite understand what you mean when you say a variable. Now I know enough to not know -- LOL

What type of variable has to be assigned?

[ronverdonk]

When you assign like

$connect = dbconnect();

you actually assign the result of the function dbconnect() to the variable $connect.
Since the function dbconnect() does not return anything, no data or boolean, the assignment has no meaning. You cannot properly use variable $connect. Maybe you don't want to, but then the assignment is useless.

OK, I see what you are saying.

The way I have used it has been many times as a straight function call

dbconnect ();

but I have also used it as in the previous example with other functions.

thanks again.

I still have a lot to learn and just don't quite completely understand the manuals and tutorials.

[ronverdonk]

Yes, a straight function call is fine. But, in this case, I would have passed on a false if an error had occurred during the connect or db select, and a true when no error had occurred.

So the statement then could be [php]if (!dbconnect())
die ("Some error at connect");
else
// continue processing[/php]

kewlness!

Thanks for that snippet, I will integrate it into my own scripts.

[tolkienarda]

maybe not the best place to put this post but...

I love this site. thescripts is the reason i have a job. i was hired to build php scripts with mysql database communication three months ago and i knew html and had heard of php but had never seen the code. now thanks to ron and other members I am building database driven sites without you guys and your detailed descriptions and fast replys to questions i probably wouldn't have a job

thanks
eric
