Functions

[tcorbeil]

Do functions execute themselves as they are declared?

 

Or do they only execute upon called on?

 

The reason is, I created a function and I have nowhere in the code called on it but it still runs itself..

 

any ideas?

it should only run when called...

[tcorbeil]

interpim, if I showed you this function of variable declaration, is there something that catches your eye??

 

<?php

 

function getvariables(){

$servername = $_SERVER['SERVER_NAME'];

$documentroot = $_SERVER['DOCUMENT_ROOT'];

$pagepath = $_SERVER['SCRIPT_NAME'];

$pi = pathinfo($_SERVER['SCRIPT_NAME']);

$slash = "/";

$pageroot = $pi['dirname']."/";

$global = $documentroot."/Global/";

$addgif = "http://www.xxxxxxx.com/Global/add.gif";

//setup for Metag Tag

$filename = basename($pagepath, ".php");   //get the filename

$formatname = str_replace("_", " ", $filename);   //get the underscores out of it.

$metatag = "xxxxxxx.com: ".$formatname;    //add the site name in front.

 

echo $servername."**";

echo $documentroot."**";

echo $pagepath."**";

echo $pi."**";

echo $slash."**";

echo $pageroot."**";

echo $global."**";

echo $addgif."**";

echo $filename."**";

echo $formatname."**";

echo $metatag."**";

}

?>

 

this function seems to get caled twice during HTML load and nowhere have I got the function called...

Hmm, when I use your function, it doesn't call it unless I call it.

 

echo getvariables();

Here's a few ideas to try:

 

1.  Temporarily change the name of the function.  Do you get any errors coming up where it was being called from before?

2.  Try changing the output of the function.  Does the output of your script change?  If no, then your function isn't being called.. it's another function which looks the same.
