The code is given below to have a look how updated code looks like
$value = array_map( function( $user ) {
return $user->user_email;
}, $users );

You can compare the code how it will look in new way
$value = array_map( fn( $user ) => $user->user_email, $users );

This code looks shorter as compare to the previous one because PHP 7.4 will make the code shorter by having only a single expression and no other return keyword. Instead of writing this complete sentence, it will have fn keywords.

* Typed Properties
After the release of PHP 7, the minor update was released in the form of PHP 7.4. This version was released for general availability. Hence this feature makes your website more reliable and faster as compared to others. PHP 7.4 was also released with the class properties features this means you can identify which type of data you are providing to it.

The support will be added if you receive a first-class property type declaration. But this version is not compatible with the callable and void support.

* Preloading
Preloading is most of the essential features that make your website load faster and helps to boost your code quicker. Due to the preloading feature, your website server can upload PH files and store the files in cache memory so that whenever you need the same file the data will get fetch from that memory instantly. Cache memory stores that data and files which are frequently used.

Due to this update, the preloading task will get controlled with opache.preload and performed with a single php.ini directive. The caution is that if you have preloaded files of a source is changed; the modification will not be affected till you have not started your server again.

* Deprecations and Removed Extensions
The new PHP updates have some changes that are unbreakable. Therefore we recommend you to take extension that is removed and the distraction which can be affected for your codebases.

The one functionality that should be removed is left-associative ternary. If you are an experienced web developer then you should avoid using nested ternary operators.

Suppose, you have used such operators then we suggest you make use of parenthesis.
The update of PHP recommends you not use left associatively for ternary operators. You are not allowed to use this operator because while transferring between languages a developer becomes confused.

Another distraction is on objects i.e. array_key_exists() along with this the curly brackets for array and string. You can find some more lists of distractions and removals by checking the new update notes.
