Hurray! That is awesome ^_^

That's my favourite addition to 5.3

!

ETbyrne · 06-30-2009, 03:18 PM

Anonymous functions are epic.

PHP Code:


			
$message = function()
{
  echo 'Hello, PHP 5.3!';
};

$message();

I don't see the point in anonymous functions. Could someone enlighten me to how they are an improvement?

cecilia · 06-30-2009, 04:06 PM

I wonder when we'll get this version. I like the way the list looks, the MySQL, Array and Date primarily.

As for anonymous, will this run?

$x = 'message()';
${$x};

OR

$x = 'message';
${$x}();

Think array_map

I can't think of a situation where an anonymous function would be required which cannot be done any other way, so it'll certainly be possibly to continue life without ever using an anonymous PHP function.

However, I see the three following scripts and prefer the new anonymous function one. It's a silly example script but I think it gets the point across.

PHP Code:


			
$subject     = 'Hello, world!';

$pattern     = '/\bworld\b/i';

$replacement = 'Salathe';



/*

    Regular, boring function

*/

function mycallback($match)

{

    // Do some complicated stuff

    return $GLOBALS['replacement'];

}

echo preg_replace_callback($pattern, 'mycallback', $subject);



/*

    Anonymous function via create_function

*/

echo preg_replace_callback($pattern, create_function('$match', '

    // Do some complicated stuff

    return $GLOBALS["replacement"];

'), $subject);



/*

    Anonymous function

*/

$callback = function($match) use ($replacement)

{

    // Do some complicated stuff

    return $replacement;

};

echo preg_replace_callback($pattern, $callback, $subject);

If you ever used javascript to a large extent you would get the idea. Just think jQuery.

Code:

$('#element').click(function(){
  // Do something
});

xenon · 06-30-2009, 05:34 PM

this is also another nifty addition, I think :)

I know this may be a stupid question but is this upgrade to php something that will halt my learning process or have they just added small features that i do not really have to worry about right now?

It's an update, they have added a bunch of new things and taken out a few things. It should not alter your learning curve if you are still on the opening section.

Thanks adamdecaf ~~ I was just making sure.

Will the next php version be 6.0?

ETbyrne · 07-01-2009, 02:48 AM

The next version will probably be 5.4, but that's just a safe guess

Kalle · 07-02-2009, 03:12 PM

PHP 6.0 is planned to be released as next major updated, and after 6.0 its been suggested to develop a 5.4 release to ease the upgrade to PHP 6.0 in the end, whilst thats a good idea for the user, i dont see a reason to develop a 5.4 because hosts will rather upgrade to a 5.4 than a new major.

Enfernikus · 07-02-2009, 03:50 PM

Kalle, you wouldn't happen to know where to get a complete list of features, upgrades, and bug fixes to php6 would you? I can't find one.

Sure, the current list of completed items are in the NEWS file in the cvs repo:
http://cvs.php.net/viewvc.cgi/php-src/NEWS?view=markup
(I actually had the joy of removing define_syslog_variables from PHP6 =))

For a list of features we plan to put into php6 as of our last PDM (PHP Developers Meeting) summit can be found here:
http://wiki.php.net/summits/pdmnotesmay09

Currently theres some ideas about putting type hinting into PHP6 aswell, but well who knows, nothing is final yet :)

ETbyrne · 07-02-2009, 10:56 PM

So what is the point of releasing 5.4 after 6.0??

Kalle · 07-02-2009, 11:03 PM

Absolutely non if you ask me

ETbyrne · 07-03-2009, 12:19 AM

I second that
