RE: [PHP] Advice on Constants - Notice: Undefined Constant

Hi, If a constant is defined, then that notice should not be coming. A constant and a variable can have the same name, but are entirely different entities. $puks = 20; define(puks, 10); echo puks.'\n'.$puks; will print : 10 20 And incase you are getting undefine notices, then it only means that for the execution of the script, the variable or the constant is/are undefined. --- Adam Douglas <ADouglas@venmarces.com> wrote: > > Notices are generated when you have > error_reporting in > > your php.ini set to E_ALL & ~E_NOTICE > > > > Notices can be helpful at times, but on production > > sites, generally donot help, because hidden input > form > > fields (not yet set), can show up as undefined. > > > > As regarding to your question, the constant is > defined > > and replaced internally in all your places in your > php > > script. > > > > Incase you want to store a constant value > dynamically > > you need to call a function called "constant", > which > > returns the value of a constant. > > > > http://in.php.net/manual/en/function.constant.php > > > > As for the NOTICE of an undefined offset, > indicates > > that the array element is not present. > > Yes I'm aware of all the bases regarding the notices > and I am aware of the > constant function.
