note 112695 added to function.define

In PHP, define does not have the same gotchas as the C-preprocessor. E.g. //In PHP: define ("x", 5+2); //x is evaluated as 7 echo 3 * x; //This is 21, as you'd expect. //But in C: #define x 5+2; //x is the string "5+2", substituted later. printf ("%d", 3*x); //This is 17. ---- Server IP: 87.124.126.49 Probable Submitter: 87.194.171.29 ---- Manual Page -- http://php.net/manual/en/function.define.php Edit -- https://master.php.net/note/edit/112695 Del: integrated -- https://master.php.net/note/delete/112695/integrated Del: useless -- https://master.php.net/note/delete/112695/useless Del: bad code -- https://master.php.net/note/delete/112695/bad+code Del: spam -- https://master.php.net/note/delete/112695/spam Del: non-english -- https://master.php.net/note/delete/112695/non-english Del: in docs -- https://master.php.net/note/delete/112695/in+docs Del: other reasons-- https://master.php.net/note/delete/112695 Reject -- https://master.php.net/note/reject/112695 Search -- https://master.php.net/manage/user-notes.php
