As far as I know there're only two ways to define a variable: the =
operator and functions that receive arguments by reference and modify
arguments:

        $var='value';

and

        function asign_value(&$foo){
                $foo='value';
        }
        asign_value($var);
        
If you mean constants, you use the define() function:

        define('FOO', 'value');
        echo FOO;
        
And if you're talking about strings, you need to consider single quotes,
double quotes and dot (concatenation operator). Double quotes make PHP
perform variable parsing in strings.
