It's now allowed in PHP 8, meaning you can do the following: As a sidenote: trailing commas are also supported in the use list of closures, this was an oversight and now added via a separate RFC. Each one of those resources gets assigned an ID, though previously the only way to know that id was to cast the resource to int: PHP 8 adds the get_resource_id() functions, making this operation more obvious and type-safe: Traits can specify abstract methods which must be implemented by the classes using them.

The "PHP CPAN", as PEAR was advertised in the times of PHP4, is now all but abandoned. Commenting on PHP 8.0, PHP programmer and stitcher.io developer, Brent Roose, noted that the latest version of the language may require developers to review code for any breaking changes. You should, when you join a team, bring that "library" with you. I believe this amazingly accurate comic [xkcd.com] might be a good reference here. PHP 7.4 comes with a remarkable amount of new features. JavaScript and Python are much the same as PHP. It takes a good year to learn Drupal. Instead of errors you'll get INF, -INF or NAN, depending on the case. This means that internal functions and methods will have complete type information in reflection. The following will trigger an error: This RFC changes throw from being a statement to being an expression, which makes it possible to throw exception in many new places: Previously, PHP used to apply the same inheritance checks on public, protected and private methods. I didn't have any breakages from 5-7 and can't even fathom how you can screw that up. PHP 7 was released in December 2015.

Why would you want to compare numbers and strings implicitly? Do you think it's good general advice for developers out there to roll their own encryption packages as well? Over the years, PHP has done a more-than-admirable job of mitigating backward compatibility (BC) where possible and documenting everything else really well.

Scout APM helps PHP developers pinpoint N+1 queries, memory leaks & more so you Since that seems to be the only explanation for not seeing this as a good feature to have. Because of the breaking changes, there's a higher chance you'll need to make some changes in your code to get it running on PHP 8. The worst thing I saw in PHP was that you could do "return flase;" [medium.com], then the word 'flase' would be converted to a string, which would evaluate as True when compared. Honestly, can someone explain why this is needed or why it's a "good" feature? Turns out it produces zillions of them. https://whydoesitsuck.com/why-... [whydoesitsuck.com].

Mostly, what they are doing turning $x = 0 + array('a'); from a warning to an error. The features of PHP7 are fairly enough for advance web application development and making use of latest resources to boost you development. He wants the U.S. to achieve net-zero … A few reflection methods have been deprecated: You should now use ReflectionType to get information about a parameter's type: If the type is a single type, ReflectionParameter::getType() returns an instance of ReflectionNamedType, which you can get its name from and whether it's built-in: If the type is a union type however, you'll get an instance of ReflectionUnionType, which can give you an array of ReflectionNamedType like so: Checking whether a type is a union or not can be done with an instanceof check: Next up, three method signatures of reflection classes have been changed: The upgrading guide specifies that if you extend these classes, and still want to support both PHP 7 and PHP 8, the following signatures are allowed: Before PHP 8, sorting algorithms were unstable. This RFC changed that behaviour, meaning reserved names can now be used in namespaces. Changes lexing of remaining tokens is related to forward compatibility.

Changes are grouped by technology area, such as ASP.NET Core or cryptography. These entity objects can not be garbage collected, as long as this cache has a reference to them, even if the cache is the only thing referencing them.

You could call it the big brother of the switch expression: match can return values, doesn't require break statements, can combine conditions, uses strict type comparisons and doesn't do any type coercion. I don't write OO code, just straight procedural code, no fancy shit, so versions 3, 4, 5, 6, and 7 were all more or less the same for me. We are educators at heart and that is the spi. I could probably throw the vast majority of my code on PHP 8 without much trouble, except maybe for a few of the functions that have been deprecated or fiddled with.

However, you can use it for other purposes as well.… Sure you can't just pick any random framework and assume that it will fit all of your needs, but as a team (assuming you are talking about more general software development practices, and not just solo "I'm Winner" type crap), you should be finding a framework that fits your common use requirements as much as possible so that you have to do much less work building things from the ground up, and "many eyes" will be on the project for defects and security issues, instead of just yours which most likely are not on it much at all. As for a quick look, here's an example of what attributes look like, from the RFC: Note that this base Attribute used to be called PhpAttribute in the original RFC, but was changed with another RFC afterwards.

Whenever you wanted to catch an exception before PHP 8, you had to store it in a variable, regardless whether you used that variable or not. following in the spirit of python and breaking all old code? And what would that breaking change be, exactly? If you need more control, you should be writing a CGI or FCGI anyway. Windows mainly .Net? Now you have n + 1 (+ many) "frameworks". This discussion has been archived. You are either lazy or don't know how computers make use of your code. Since some of these breaking changes are in obscure parts of the framework only a portion of these changes may actually affect your application. Specific usages of Attributes in PHP 8 can lead to code that compiles very differently on PHP 7 but still runs. Heavy weight Java? See Andrei Alexandrescu's post on optimization [fb.com] where he mentions: On x86 pointers can access byte-aligned data whereas other platforms pointers MUST be 4-byte, etc., aligned else you get a hardware trap. Perl 5, just nope; went Ruby instead. It was extremely ugly, but is not actually that much worse than other languages that lack static typing. It is easy to deploy. There may be more comments in this discussion. It's good to see more modern languages thinking of efficiency instead of treating RAM as an infinite resource. Everything is in the "frameworks": Symfony, laravel, Zend and alike. The new fdiv() function does something similar as the fmod() and intdiv() functions, which allows for division by 0. Cannot add element to the array as the next element is already occupied: Cannot unset offset in a non-array variable: Array to string conversion: warning instead of notice, Resource ID#%d used as offset, casting to integer (%d): warning instead of notice, String offset cast occurred: warning instead of notice, Uninitialized string offset: %d: warning instead of notice. It works the same way as get_class(). Umm, was that supposed to be simpler? Also, was the ternary operator evaluation order ever fixed? But unlike a strongly types language, these Python3 versions just fail silently, insidiously, without any hint or warning the code isn't doing what you might expect.
