Global variables 1 Year, 11 Months ago  
Hi,
Am trying to get global variables working (sourcerer 2.4.2 - excellent btw - thanks!).
Even a simple;

{source}
<?php
$a = 1; /* global scope */
function test()
{
    global $a;
    echo "test=".$a."END<hr>"; /* reference to local scope variable */
}
test();
?>
{/source}

only displays "test=END" for me...
If I run the same from a dos window directly with php, "test=1END" works.

Any ideas why? Is it joomla or sourcerer or me?

many thanks for any help
pn
Phil

Re: Global variables 1 Year, 11 Months ago  
You have to define the variable to be global from the start.
Try this:
{source}
<?php
global $a; /* global scope */
$a = 1;
function test()
{
    global $a;
    echo "test=".$a."END<hr>"; /* reference to local scope variable */
}
test();
?>
{/source}
