Application

[Anon]

May I know how to declare application variables in PHP?

Thank you.

Variables in PHP do not need to be explicitly declared. If it makes you feel better, or if you (like myself) prefer to initialize them for clarity:

<?php

$myVar = 0;
$myString = "";

?>

The only time that varibles DO need to be declared is when they are properties of an object class. In that case you must use the "var" keyword:

<?php

class myClass {

var $myPropertyOne;
var $myPropertyTwo;

// define class methods

}

?>

Sorry that I didn't make myself clear.

I want to know whether I can declare application variables, e.g. application.host in ColdFusion or application("host") in ASP?

Thank you for the reply.

I don't think that PHP has "application" variables in that sense.

Most sites implement that functionality by putting an "include('site.inc')" or something to that affect at the top of the scripts. The site.inc file contains script that retrieves required values from a file or database or defines site specific variables/constants. You can put a function in there that allows you to modify values from other locations in the main script body if necessary.

It's a little extra work, but it achieves the same results.
