Thanks for the feedback. (A) "This is illustrated in the following example: " but then follow TWO examples, 19-1 and 19-2. English grammar requires "This is illustrated in the following examples: " And the examples are a bit meagre. The oop4 documentation was richer. (B) 2) "How to add a member to the class on the fly" I fail to see what you're trying to describe here. It is allowed to add member fields to just one instance. given class fruit has no field "sweet", one can add one to an instance, simply by $apple->sweet=true; (C) >>Until you've something new, this bug report seems bogus to me. Maybe, but classes, from the manual, have a very steep learning curve, even in php terms. (D) The reference to the class/object handling functions is missing. >From this it is unclear whether oop5 augments, or replaces oop4 documentation. Previous Comments: ------------------------------------------------------------------------ [2006-05-01 13:47:39] [EMAIL PROTECTED] 1) "How to define a member, How to define a method" This is explained in this example: http://php.net/language.oop5.basic#AEN5708 2) "How to add a member to the class on the fly" I fail to see what you're trying to describe here. 3) "Constructors: the classname($var) syntax" This is already documented: "For backwards compatibility, if PHP 5 cannot find a __construct() function for a given class, it will search for the old-style constructor function, by the name of the class." 4) "There can only be one constructor, as opposed to C++." Who said PHP was like C++? This is how PHP works, you can't define two functions with the same name having different parameters. 5) "Further, when there is a constructor, the new operator has to use it." This is how functions/methods generally work, if an argument is not optional, you've to specify its value, nothing new/undocumented. Until you've something new, this bug report seems bogus to me. ------------------------------------------------------------------------ [2006-05-01 13:45:56] php-bugs at T43 dot mine dot nu The scope of members, defined on the fly (not in the class definition), is not specified. given $this->newmember='sweet', is newmember public? given $apple->newmember='sour', is newmember public? ------------------------------------------------------------------------ [2006-05-01 13:40:38] php-bugs at T43 dot mine dot nu The oop5 documentation does not point to the class handling functions (as the oop4 documentation did, on the very first, the 'class' page at the end.) ------------------------------------------------------------------------ [2006-05-01 13:29:34] php-bugs at T43 dot mine dot nu more missing. There can only be one constructor, as opposed to C++. So function classname($var1,$var2) can't coexist with function classname($var1) . Further, when there is a constructor, the new operator has to use it. Given function classname($var1), the call $apple= new classname; fails, but $apple=new classname('apple') is required syntax. ------------------------------------------------------------------------ [2006-05-01 13:17:11] php-bugs at T43 dot mine dot nu Description: ------------ the oop5 documentation has a lot of unclear / missing very basic passages. Among them are: Basics: How to define a member, How to define a method How to add a member to an instance ($apple->newmember) How to add a member to the class on the fly Constructors: the classname($var) syntax The sentence "Followed by a pair of curly braces, OF which contains the definition " the word 'OF' is grammatically wrong in the ears of non-english, making the sentence non-understandable. Most of this was missing in the php4 class documentation too. It is not clear whether the php5 class chapter replaces, or augments the php4 class chapter. I can't fix it as I can't delve into the sources of ZEND engine and the like. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37258&edit=1
