        I use php and do enjoy it but it is ugly. There is no consistency within the function naming, using -> over . Or any other single symbol is dumb and __construct() but why two underscores? It's unnessary.

          __construct() is a magic method, just like __get(), __set(), __destruct(), __isset(), __toString(), so on and so forth. Magic methods are called without the programmer having to call them, under specific circumstances. In the case of __construct(), it's called when an object is instantiated. '__' defines a magic method and was chosen back in the day because PHP didn't have protected/private members and so the common practice was to prefix private/protected members with one underscore.

          PHP was a solution to Perl, so -> is what Perl uses so that's what PHP uses.

          The function naming is not so much an issue either. But what is frustrating is argument order. That's something that really needs to be revamped, backwards compatibility be damned.

            Assuming your argument-order frustration lies with the classic needle/haystack inconsistency throughout the string and array functions, the whole issue goes away if the PHP guys would simply evolve the string and array natives to be treated like objects:


            in_array($needle, $haystack) -> $array->contains($needle)

      • Having used PHP along with a whole slew of other languages, what I've generally found is that like most other languages PHP is a bit of a slave to its own history.

        For PHP, its origins in dynamic web pages lead it towards results which are quick and often convenient for web designers who are great at making sites pretty, but lacking in design consistency and rigor. Some effects of this are APIs with inconsistent naming and structure compared to other languages, and the prevalence of bad code practices among

And after converting my development wholesale to python with it's inherent namespaces (which are really just singleton objects bound to a local name), it seems like PHP's system is a bit convoluted.

      Nothing is broken. Ereg is moved to the 'official' extension pack called PECL, which you can use for full backwards compatibility. At the same time the community has been warning not to use the ereg functions for the past at least 3-4 years, if not more, citing worse performance, worse featureset, and the possibility of PCRE replacing it at some point in the future.

Plus it's just extra code that there's little reason to continue patching and porting a decade after it has been superseded by faster, safer functions.
