[SOLVED] Variables in Functions

[UnsuitableBadger]

Hi everyone

 

I've got a main entry point file (index.php) which looks as follows:

 

require('variables.php');
require('functions');
require('tasks');
myFunction();

 

in the variables.php file I have:

$myVariable = 1;

 

in the functions.php file I have:

function myFunction()
{
   echo $myVariable;
}

 

in the tasks.php file I have:

   echo $myVariable;

 

My question is how come the tasks.php file will echo out the content of $myVariable but when calling myFunction() from the index.php it doesn't recognise the variable.

 

Do functions just ignore any variables that are not passed to them or that are not global variables.

Any ideas of how to make this work?

No problem. I just like to help those who are starting off. I remember the first time I encountered a variable scope problem. I was learning VB, and wanted to globalize a variable, but I had no idea what to do, and neither did my teacher (He was useless). So because I had no idea what to google, I reverted to using a caption, hiding it, and storing my variable data in it. Good times. Anyway, good luck
