If $a = 'foo' and $$a = nothing (i.e. no value assigned to $foo) you will get an error if you tried to use this to do something else. On Sun, Mar 6, 2011 at 3:21 PM, tedd wrote: > At 6:42 PM +0530 3/6/11, Ashim Kapoor wrote: > >> Dear All, >> >> I was reading the php manual for session_register,

Re: [PHP] $$var

Hi Ashim, These are called Variable Variables. Ideally they should be avoided, as they introduce unnecessary legibility issues. This is what it does in a nutshell, it's actually quite simple: $foo = 'bar'; $bar = 'foobar'; echo $$foo;//This prints foobar What it does is, take the value of $

If I were you, I would use the following: if (!is_a ($miInstancia, 'db')) $miInstancia=new db(); That way you can ensure that the variable has been instantiated and is an instance of the db class.. But it may not really matter.. Jordan S. Jones Alvaro Martinez wrote: I've found the solution m

Globals!? YUCK :) A better solution IMHO that maintains encapsulation, is to use a static var in a function: function &getClassVar( $name ) { return getAndSetClassVar( $name, false ); } function &setClassVar( $name, $value ) { return getAndSetClassVar( $name, true, $value ); } function &

Although PHP supports static variables in functions (see here), it has no support for static variables in classes. http://www.php.net/manual/en/language.variables.scope.php (espero que te sirva) saludos aniceto lópez :: DYNAMICAL.BIZ web development & host services Barcelona - Spain -Me

Re: [PHP] Var question

is go a variable that is passed via post? I guess yes but you get this error without submitting yet. There are three solutions: 1. Change your error reporting level to 55: error_reporting(55). This will stop warning your undefined variables. 2. Prefix the variable with an at-mark: @$_POST['go
