Where did this myth start up in the first place? Was it just because they
happened to announce SQLite support at the same time as removing the bundled
MySQL client library? (client library != the PHP MySQL extension).

MySQL support is not being removed; in fact it's being improved (see the
mysqli functions).

If you like OOP, you'll probably get a kick out of the new object
model. If you understand OOP, you will still be wondering how
much sense OOP makes without strong typing. If you don't like OOP,
it'll be a huge disappointment: slightly larger system footprint,
but no additional functionalilty; just another step along the way
of turning PHP into a Java clone.

Nik,

I heard there was quite a performance increase over the 4.x branch too. I
can't say I've had the pleasure of trying PHP5 as yet, been too busy.. I
may be wrong, but I thought I read somewhere that performance and a few
other "efficienci es" had been incorporated. Feel free to correct me if I'm
wrong.. I'm interested to hear PoV from people that have tried it too =)



Regards,

Ian

Hi,

I found this link, which shows the OOP Concepts implemented under PHP5

Well, there are quite a few people who make this queston other way around,
how mocu sense does OOP make with strong typing? Especially inventors of OOP
like Alan Kay.

SmallTalk is regarded as one of the most Object Oriented languages
available. It does not use strong typing, but dynamic types. Just
like PHP.

You sound rather bitter, did Java steal your girlfriend or
something?

Better an unencumbered Java clone than a hastily-hacked-together
scripting language, hey?

We have to learn Java somehow, and we sure can't via Sun's tutorial. :)

http://www.mindprod.com/jgloss/jgloss.html can be useful.

It's curious how Apache are supporting both Java and PHP.

It must produce some level of schizophrenia internally.

Re: PHP5 - *ANY advantage??

The features I'm looking forward to using are destructor and property. They
allow you to very neatly encapsulate your database access code. Say you're
writing a message forum webapp. You would have a Message class that looks
something like this:

class Message {
private $values;
private $columns_change d;
private $primary_key;

function __destruct() {
if($this->primary_key) {
$this->DoDBUpdate() ;
}
else {
$this->DoDBInsert() ;
}
}

function DoDBUpdate() {
foreach($this->columns_change d as $column) {
...
}
}

function __set($name, $value) {
if($this->values[$name] != $value) {
$this->values[$name] = $value;
$this->columns_change d[] = $name;
}
}

function __get($name) {
return $this->values[$name];
}
}

To insert a message, you'll would do something like:

$msg = new Message();
$msg->title = $_POST['title'];
$msg->text = $_POST['text'];

Assignments to the undeclared variables title and text triggers the objects
__set() function, which records the names of these properties so that it
knows which table columns to update. When the object is destroyed, the
destructor is triggered, which save the changes to the database.

Property access is great in that it fits in perfectly with one of PHP's
great strength: variable interpolation (i.e. sticking variables into
double-quoted strings). You can now, in essence, call a function from within
a string. Using the message forum example again: When you out put a message,
you'll find inevitably that you need to do a htmlspecialchar s() on most
properties of Message. In PHP4, you would have to either use a lot of
temporary variables or break up your strings into ugly fragments ( "<h1>" .
htmlspecialchar s($msg->title) . "</h1>" ). In PHP5, you can modify __get()
like this:

function __get($name) {
if(substr($name , -5) == '_html')) {
$need_htmlspeci alchars = true;
$name = substr($name, 0, -5);
}
$value = $this->values[$name];
if($need_htmlsp ecialchars) {
$value = htmlspecialchar s($value);
}
return $value;
}

so that all you have to do is to append the suffix '_html' to a property
name to get it properly escaped ( echo "<h1>$msg->title_html</h1>" ).

Last time I heard, invention of OOP was attributed to Niklaus Wirth...
But, then, I may be listening to wrong people... :)

Honestly, I could not care less about Java; it exists in a universe
totally separate from mine. The reason I am bitter is because the
current PHP team seems to develop PHP in ways that are totally
irrelevant to me and my needs. For example, I would rather have
PHP totally void of OOP, but with a good statistical library
included in the standard distribution (good statistical libraries
are not object-oriented anyway).

No it shouldn't. Apache simply decides which module to call
to parse a file with a particular extension. And options
may, in additions to Java and PHP, include SSI, Perl, Python,
etc...

I mean within the Apache Software Foundation - e.g. when it comes
to allocating funds.
