Accepting Change: Getting Ready for PHP 8.3

With the release of PHP 8.3, numerous updates and modifications are included. Even though change can be intimidating, this will make it easier for you to get around in PHP 8.3’s new environment.

Getting By With Deprecations

How Come Your New Best Friends Are Deprecations?

Deprecations serve as helpful indicators of impending changes to the road. These indicators mostly relate to PHP 8.3 cleanup in preparation for PHP 9. Experiencing a devaluation? Often, the easiest thing to do quickly is to update the composer. If not, a few adjustments to the code ought to work.

Note a Few Important Deprecations:

Operators for Increment and Decrement: It is not recommended to use ++ or — on non-numeric strings.

$word = "apple";
$word++; // PHP says, "Let's not."

Class Functions with Arguments: You’ll need arguments for get_class() and get_parent_class(). Free rides are over!

echo get_class(); // PHP 8.3 says, "I need more details!"

Changes to the FFI API: Cast, new, and statically typed calls are no longer possible. Observe those function signatures closely.

Update for the SQLite Library: Soon, warnings will become exceptions. Deprecated is the function enableExceptions(false).

Awaiting Radical Shifts

It may seem frightening to break changes, like when your favorite mug is dropped. However, these are frequently merely essential steps to improve PHP.

Some Radical Shifts to Pay Attention to:

Proc_get_status Fix: Resolved a problem wherein posix systems were returning incorrect values.

$status = proc_get_status(); // Old way
$status = proc_get_status($process); // New and improved

Trait Static Properties: They redefine properties inherited from parent classes, and they behave differently now.
Negative Index for Arrays: Adding an element to an array that had a negative index used to cause strange behavior. PHP now handles it with greater logic. An item in an array with a negative index will no longer default to index zero when it is added.

$array = [];
$array[-1] = "old value";
$array[] = "new value"; // PHP now handles this better

Prevention of Memory Overflow: PHP now raises an error if it approaches a memory overflow because of recursion.

Garbage Collection and WeakMap: Garbage collection is now possible for WeakMaps that self-reference.

Changes to the DOM Classes: Review the most recent list if you depend on PHP’s DOM classes.
