I want to make it possible to echo variables
Without having defined them already
Like $var = "$var2" but that var2 has no value but will get it were it gets echo'd

description of problem was enough, no code necessary -- coopster

Not sure I understood you clearly but I would say NO.

A variable is a variable and must have a value.
If not value is given, then the variable is NULL (that is $var="")

PHP has some nice built-in functions to test whether a variable exists yet. I would probably assign the value after checking to see if the variable isset() [php.net] yet. I often use the ternary operation to do so ...

$var = (isset($var1))? $var1 : 'default_value';

This type of approach comes in very handy -- especially when checking to see if a user has filled in an HTML <form> value.
