note 84411 added to language.constants

Reply to ian at willis dot org dot uk From the second line of the Syntax section above: "Only scalar data (boolean, integer, float and string) can be contained in constants. Do not define resource constants." So the 'ccc' value of your constant would be interpreted by php as the string 'ccc', not a reference to the function. Furthermore the cfunc(); call that triggers the error, as far as PHP is concerned, is just a normal function, since constants have no $ prefix, if you used a constant as a reference to a function, how would PHP know what should be handled as a regular function call and what should be handled as a constant function reference as the syntax becomes the same. You can create a variable from the value of the constant using ${CFUNC} so to create a reference to the function from the constant you might be able to do: <?php define("CFUNC", "ccc"); ${CFUNC}(); ?> I haven't tested this though and in all honesty I can't think why you'd even want to use a constant as a function reference anyway for variable variables it make's sense, particularly when you might not know the function name beforehand. A constant is as it's name implies - it's constant, since it's value doesn't change it has no benefit as a function reference as far as i can see since you must already know the function name (that you set as the value of the constant) in order to create this constant reference, why not just call the function directly? ---- Server IP: 92.48.74.199 Probable Submitter: 84.70.170.214 ---- Manual Page -- http://www.php.net/manual/en/language.constants.php Edit -- https://master.php.net/note/edit/84411 Del: integrated -- https://master.php.net/note/delete/84411/integrated Del: useless -- https://master.php.net/note/delete/84411/useless Del: bad code -- https://master.php.net/note/delete/84411/bad+code Del: spam -- https://master.php.net/note/delete/84411/spam Del: non-english -- https://master.php.net/note/delete/84411/non-english Del: in docs -- https://master.php.net/note/delete/84411/in+docs Del: other reasons-- https://master.php.net/note/delete/84411 Reject -- https://master.php.net/note/reject/84411 Search -- https://master.php.net/manage/user-notes.php
