[RESOLVED] single vs double quotes

[netfrugal]

This is a question regarding the correct times to use either the single vs double quotes.

I define a variable inside variables.php:

define('NAME', 'john Smith');

When I include this file inside another file:

include('variables.php'); 
echo NAME;

I don't get the desired result: John Smith
However, this only works on one of my servers. When I change the include function to have double quotes, it works!

include("variables.php"); 
echo NAME;

result: John Smith

Is this a certain setting in apache or php.ini ? Or does the latest version of PHP only allow perfection with single & double quotes?

Weird, now it started working both ways. 😕

Ok, I guess we can ignore this post! :glare:

Could have been a browser cache problem. You could have had a cached page that wasn't allowing it to work for you. Just needed to hit refresh to get a new copy instead of the cached browser page. You can use single quotes unless you want to phrase a variable inside the quotes then use double quotes. You don't need the () either.

include 'variables.php';
echo NAME;
