![]() The code analysis across the project then reported all the usages of deprecated functions. shows tool tip information for named argumentsįunctions used to be annotated with PHPDoc tag.highlights the parameter in signature helper.for each parameter shows type information, documentation, and default value.recognizes the function being called, and lists relevant parameters.The IntelliSense for named arguments features the following: Also it should report any unknown argument names. The editor however has a lot to do - there is code completion, that should provide list of available parameters, auto-complete the colon character if necessary, provide related parameter information, adjust the highlighted section of the signature helper, provide tool tips for named arguments, and more. The ability to specify the arguments by their name is a great feature that makes the code more readable, allows to skip parameters with default values, and may avoid some errors when there are too many arguments in a single function call. Upon switching the project to PHP 8.0, the warnings will be gone. The editor reports all those usage in case the project is set for PHP version <= 7.4. It might be the trailing comma in function parameter list, attributes, match expression, throw expression, or catch without the variable. With PHP 8, developers will start using the new syntax options. It will provide a detailed completion for named arguments, validates their use, checks the new syntax, warns about deprecations, and more. Let's have a look at how the editor in Visual Studio helps with those features. Get in touch with us here if you’re looking for a quick and hassle-free upgrade.PHP 8 introduces a new syntax, more functions, and new standards. ![]() ![]() We have a team of experts that’s well versed in PHP. Since the update has breaking changes, it’s advisable to have experts help you with the migration to avoid any unexpected downtime. Match branches only support single-line expressions and do not need a break statement. Match is an expression, meaning its result can be stored in a variable or returned. The new match is similar to switch and has the following features: $country = $session?->user?->getAddress()?->country PHP 8 Match expression In case of chain failure, the execution of the entire chain aborts, and the entire chain evaluates to null. In the latest version you can use a chain of calls with the new nullsafe operator instead if null check conditions. New Number(‘NaN’) // TypeError PHP 8 Nullsafe operator Instead of PHPDoc annotations for a combination of types, you can use native union type declarations that are validated at runtime. Less boilerplate code to define and initialize properties. Instead of PHPDoc annotations, you can now use structured metadata with PHP’s native syntax. Htmlspecialchars($string, double_encode: false) PHP 8 Attributes Arguments are order-independent and self-documented. Specify only required parameters, skipping optional ones. Htmlspecialchars($string, ENT_COMPAT | ENT_HTML401, ‘UTF-8’, false) Here’s a lowdown of the official update announcement: PHP 8 Named arguments Some of the major features and optimizations introduced in this update are named arguments, union types, attributes, constructor property promotion, match expression, nullsafe operator, JIT, and improvements in the type system, error handling, and consistency. Comes with a few radical alterations, so there’s a high chance you’ll need to make a few changes in code before upgrading. It’s a typical three-year cycle version upgrade of PHP. The latest major update in PHP 8 has been made available to the public.
