debug function

[lambrite]

I have a very simple debugging function that I wrote, that doesn't work.

$debug_On = true;
function debug($debug_line)  {
	if ($debug_On == true) {
		echo $debug_line."<br>";
	} else { 
		//don't print
	}
}

• When I test for the condition "true", it doesn't ever echo the line.
  

• When I set $debug_On to "true" or "false" and check for 0, it always echos the line.
  

• When I set $debug_on to 0 or 1, and check for 0, it always echos the line.

The function is the first thing on my page, and I reference it by

debug($somevar);

Am I just missing something obvious? (I know I don't need the else clause, but it doesn't work when I take that out, either.)

Thanks
Sarah

I'm guessing global variables are not working for you and $debug_On is outside the scope of your function.

Another approach to this problem, without using global variables, would be to use a constant. You could do:

define('DEBUG_ON', true);

function debug($debug_line)  {
    if (DEBUG_ON == true) {
        echo $debug_line."<br>";
}
