#define in PHP

Posted by stockton (stockton), 10 August 2007
I hope that this is not the wrong forum but I would like to do the same as one would in C and that is in an included configuration file #define a variable that could then be checked throughout the rest of the PHP system for TRUE or FALSE.
In C I used to #define TRUE 1 then #define FALSE !TRUE and therefore one could #define SQL TRUE
Effectively I would like to
$SGM=True;
& then further on in the system
if ($SGM)
{
echo '<script language="JavaScript" type="text/javascript" src="js/ajaxSGM.js"></script>';
}
else
{
echo '<script language="JavaScript" type="text/javascript" src="js/ajax.js"></script>';

}

Is this possible or better yet is there a better way?

Hi, Alf.

The syntax you're using is more or less correct - although I would use 0 and 1 for true and false.

It's common practice to have a whole file of constants and settings in a file you include in a number of PHP pages.    So the PHP will include:

require("settings.inc");

and settings.inc will include things like:

$SGM = 1;
$swlip = "192.168.200.67";
