Assigning to an undeclared variable out of a class has no meaning in PHP, because there are no declarations of variables outside of a class. Declarations of variables inside of a class are pretty much for documentation or initialization to a constant, but to be consistent with the general theme of PHP assignment and PHP as a loosely-typed language, it's perfectly legal syntactically and logically to assign to a new property on a class. So you're probably never gonna see a warning for assigning to an undeclared variable, even in the class system... It would have to be, like, E_SO_STRICT_YOU_SHOULD_BE_USING_C_ANYWAY :-) You SHOULD be using E_NOTICE to get warned when you *USE* an unassigned variable/propery/element and PHP is forced to initialize it. That will catch a bunch of your variable name typos -- And also will often let you know you typed it wrong in the place where you did the assignment. EG: <?php $mispeled = 'test'; //line 2 echo $mispelled; //line 3 ?> The typo is in the assignment, but you'll get warned in line 3. Composing a more convoluted example involving a class and 100 lines of code is left as an exercise for the reader. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
