在joomla中包含我自己的全局变量和php函数

Question

I´m trying to include mi own functions in joomla code to set the header and footer of the home page of my site, As I can see, including php files works fine, but functions can not acces vars outside them.

For example:

function test () {
     echo 'ok';
}

works without problems, but:

$test = 'ok';
function test () {
     global $test;
     echo $test;
}

does not work, so, when I call a file wich contains the functions, most of them require global variables located outside them, therefor they dont`t work as in the example I typed.

Anyone can help? Thanks in advance

Answer 1

add $ to echo $test;

$test = 'ok';
function test () {
   global $test;
   echo $test;
}
