#Php 8 new switch update#
There has been a critical error on this website. Change language: Released PHP 8.2 is a major update of the PHP language. Right now, I installed a fresh WP on other server. But I guess if you have already used switch with more than one expression you are already doing-it-wrong.As I said in the main post, this error is present if plugins are disabled. One important note: match does not support multi-line only one expression like arrow functions.
#Php 8 new switch plus#
This plus the strict type checks should prevent any bugs which may otherwise get unnoticed and cause unexpected behaviour of your code. Match fixes also another quirk of switch: Any unhandled case will throw an UnhandledMatchError exception. And you only have to combine multiple conditions by a comma. The value only needs to be assigned once. This should look familiar when you work with short closures (arrow functions) which were introduced in PHP 7.4.
🤩Īnother benefit? It’s so much shorter as it does not have break or return statements. It contains many new features and optimizations including named arguments, union types, attributes, constructor property promotion, match expression, nullsafe operator, JIT, and improvements in the type system, error handling, and consistency. Match does strict type checks by default and and so the output will be the expected default case. Released PHP 8.0 is a major update of the PHP language. The same example with match: $value = '' (PHP 8) The match expression branches evaluation based on an identity check of a value.
Why? Because switch is doing loose (=) checks. Let’s take a look at a the following switch example: $value = '' Ĭorrect, it’s not default but null. 0 (integer) is no longer equivalent to '' (empty string.
String to number comparisons are now saner. A number of additional changes in this area enhance the strictness and consistency with which type checking is enforced. It’s similar to the switch statement but match will probably become your number one choice once you know the differences. We’ve already looked at how Union Types add another layer of flexibility to the PHP 8 type system. When we turned on PHP 8.0.0.26 it just instantly generates 500 internal server error. As of PHP 8.0 a new expression named match is available. Pretty much as said in the subject headline.
