PATH_SEPARATOR already defined??

lplatz · July 7th, 2006, 06:16 PM

I am following a tutorial primarily to learn MySQL and PEAR. I'm been using PHP5 with Apache on my development system with no issues. I installed MySQL 4.1.20 and current version of PEAR (both appeared to load correctly).

ISSUE: when loading my index page, I get the following:
Notice: Constant PATH_SEPARATOR already defined in C:\My Documents\Web Business\tshirtshop\include\config.inc.php on line 25

//config.inc.php - line 25 referenced:
  define("PATH_SEPARATOR", ";");

//The complete code line 25 is associated with:
if ((substr(strtoupper(PHP_OS), 0, 3)) == "WIN")
  define("PATH_SEPARATOR", ";");
else
  define("PATH_SEPARATOR", ":");
ini_set('include_path', SITE_ROOT . '/libs/PEAR' .
         PATH_SEPARATOR . ini_get('include_path'));

If I comment out the following lines: (see below) the Notice goes away

//if ((substr(strtoupper(PHP_OS), 0, 3)) == "WIN")
// define("PATH_SEPARATOR", ";");
//else
// define("PATH_SEPARATOR", ":");
ini_set('include_path', SITE_ROOT . '/libs/PEAR' .
         PATH_SEPARATOR . ini_get('include_path'));

I don't believe I am connecting to the MySQL database ("tshirtshop") I set up.

I recognize that the number of variables that may be impacting this could be infinite. I, however, need to begin debugging this with the help of someone with far superior experience with PEAR and MySQL than I. I have attempted, through trial and error, to figure this out (primarily due to the fact that I didn't even know how to ask for help with this issue until I found this group).

Much appreciation for any and all input/help resolving this issue.

It seems like two things are requiring or including config.inc.php, and therefore PHP tries to execute the code twice. The fix would be to use require_once or include_once instead of require or include, respectively. If you do this, PHP will make sure the include doesn't get executed twice and therefore fail.

The question is, however, what's including config.inc.php twice? Is some library you're using including it explicitly? It seems weird that PHP would run into this error with a default configuration.
