      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content.

Use   for small snippets of code Use   for lengthy snippets of code Use   if your snippet is HTML (optional) Use   if your snippet is SQL (optional) Rules of Conduct   Be nice. There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

PHP 7 Is Available

Recommended Posts

justsomeguy    954

From their email:

 

Today, were pleased to announce that PHP 7.0 - the fastest and most efficient PHP ever - is officially released!

 

PHP 7.0 brings you unprecedented levels of real-world performance and throughput by utilizing the new and advanced Zend Engine 3.0, designed and refactored for speed and reduced memory consumption. This translates to real-world benefits: greatly decreased response times, superior user experiences, and the ability to serve more users with fewer servers to maximize the power of your PHP 7.0 deployment.

 

The explosive performance improvements of PHP 7.0 range between 50% and 200% on real-world apps - without changing a single line of code.

 

PHP 7.0 also uses much less memory thanks to the compact data structures and the highly-refactored codebase of Zend Engine 3.0. Memory consumption gains between 30% and 50% are commonly realized, allowing you to serve more concurrent users without adding additional server hardware.

 

If light-speed PHP isnt enough, youll be happy to know that PHP 7.0 comes with many new features, including Return Type Declarations, Scalar Type Hints, Anonymous Classes, and even a SpaceShip Operator. Check out our PHP 7 Resources page. Further details are available here.

For those who don't know, with the release of PHP 7 the old mysql extension is no longer supported, which is why we tell people posting code that uses that extension that they need to update their code. Alternatives include the mysqli extension and PDO.

I know that's in jest, but there are reasons for both of those. They skipped PHP 6 because after PHP 5 they made a lot of promises about what PHP 6 would be (importantly native Unicode support), but they had problems with implementation. They moved several features that were planned for PHP 6 into the later versions of PHP 5 (namespaces, traits, etc), and decided to call the next version PHP 7 to make sure that people weren't expecting Unicode support and since there were already books and things referencing PHP 6 which wouldn't have been correct. As far as Microsoft goes, they skipped Windows 9 because of all of the old code checking if the OS name started with "Windows 9" to detect Windows 95 or 98. Those programs would have crapped the bed if they detected the new version of Windows as Windows 98.

Really? I heard it waz because 9 is considered unlucky in Japan, and trendmicro did the same, also because

 

"Windows 7 8(ate) 9 so only option to go to 10" :-)

Yeah, a lot of older applications check if the OS name starts with "Windows 9", and if so they run older code versus the code that was meant for the NT line. It's a really lazy check to make when they could check if it's "Windows 95 or Windows 98", but that's the way it goes. Microsoft decided to just avoid the possible problems completely instead of try to explain why so many applications started failing.

It is really a very good news that PHP 7 is available now for developers, there were some alpha and beta updates were coming, but complete version was still awaited, I am curious to work upon it.

Fwiw, I upgrade to PHP7 a couple months ago, both for my local development environment using Vagrant, and in AWS. No complaints so far and everything was easy to get work using. My project was pretty green anyway and was just a backend API to my UI, so I didn't have any good reference as far as performance and benchmarks.

Is Sql is working in PHP7?

Please say then I can install from

 

http://www.php.net

 

I had no problems with my existing source code. No code changes had to be made on my part so PDO, Slim, JWT, etc all still worked for me. It was mostly updates to my Vagrant script (local env ) and development / production servers, to leverage this PPA for the packaages I used to upgrade PHP, Apache, and MySQL

https://launchpad.net/~ondrej/+archive/ubuntu/php

 

I'm using Ubuntu 14.04 as my base box.

 

I relied heavily on my unit and integration tests to sanity test and assure confidence in my existing functionality and haven't had any regressions to report.

Why is the Spaceship Operator not mentioned anywhere in the W3schools webpages?

The W3Schools tutorials only cover PHP 5.
