PHP, a stalwart in web development, raises the bar with PHP 8.3. Focused on performance, code quality, and workflow transformation, this open-source update merits a detailed exploration. Continuing its annual tradition, the PHP project unveils PHP 8.3, reinforcing its versatility with new features. Explore the notable additions and changes in this article.
Let's delve deeper!
Embark on PHP 8.3's Transformative Key Features
Let’s look at the new additions of PHP 8.3 that have been launched
1)Typed Class Constants
In PHP 8.3, typed class constants enhance type coherence, reducing the risk of inadvertent deviations in class, interface, trait, and enum constants. Beneficial for maintaining type uniformity in subclasses
php
interface ConstTest {
const string VERSION = "PHP 8.3";
}
// Illegal:
interface ConstTest {
const float VERSION = "PHP 8.3";
}
2) stream_context_set_options Function
With PHP 8.3, a superior function, stream_context_set_options, takes center stage, outshining its predecessor by efficiently managing multiple options. This advancement is set to replace the original function in future PHP versions. "This update improves stream context manipulation, offering a versatile and future-proof API for enhanced functionality and adaptability."
php
stream_context_set_options($
stream_or_context,['http'=>['method' => 'POST']]);
3) Randomizer::getBytesFromString Method
In PHP 8.3, the \Random\Randomizer class introduces the getBytesFromString method, enabling the creation of random sequences from a specified character string. This feature enhances versatility in secure data generation.
$rng = new Random\Randomizer();
$alpha='ABCDEFGHJKMNPQRSTV
WXYZ';
$result1=$rng->getBytesFromString($alpha,6);// “MBXGWL”
$result2 = $rng->getBytesFromString($alpha, 6);// “LESPMG”
$result3 = $rng->getBytesFromString($alpha, 6);// “NVHWXC”
4)PHP INI Environment Variable Syntax Now Supports Fallback Values
In PHP version 8.3, developers can now set default values for PHP INI settings when certain environment variables are absent. This enhances configurability and simplifies configuration management.
php
//Fallback to 'Foo' if SESSION_NAME is not set
session.name=${SESSION_NAME:-Foo};
//Fallback to 'info@example.com' if MAIL_FROM_USER or MAIL_FROM_DOMAIN is not set
sendmail_from="${MAIL_FROM_USER:-info}@${MAIL_FROM_DOMAIN:-example.com}";
5) PHP 8.3 Enhances class_alias() to Support Built-in PHP Class Aliasing
In PHP 8.3, the class_alias() function now accommodates the aliasing of built-in PHP classes, providing developers with increased flexibility in code structuring and naming conventions. This enhancement fosters more organized and expressive code when working with native PHP classes.
php
class_alias(\DateTime::class, 'MyDateTime');
$customDateTime = new MyDateTime();
6) Improved Dynamic Class Constant Retrieval and Enum Number Fetching
PHP 8.3 simplifies accessing class constants and enum members dynamically, replacing the complex constant () function with a more readable syntax for streamlined dynamic access.
php
$constantName='THE_CONST';
$memberName = 'FirstMember';
echo MyClass::{$constantName};
echo MyEnum::{$memberName}->value;
7) Randomizer::getFloat() and nextFloat() Methods
PHP 8.3 adds precision and control with new float generation methods: getFloat() and nextFloat(), enhancing the Random extension for versatile and accurate random floating-point values.
$rng = new Random\Randomizer();
// Generate a float value between 0 and 5
$result = $rng->getFloat(0, 5); // 2.3937446906217
8) json_validate() Function
PHP 8.3 introduces json_validate(), simplifying JSON syntax validation without the need for decoding, saving memory. Ideal for pre-validating JSON payloads in request-response scenarios.
php
if (json_validate($maybeJSON)) {
// Perform actions with $maybeJSON
}
9) gc_status() Now Returns Additional Information
In PHP 8.3, the gc_status() function, providing garbage collector statistics, is enhanced to include additional details like ongoing status, protection status, and buffer size for a more comprehensive insight into its behavior.
php
$gcStatus=gc_status();
echo"Running:".$gcStatus['Running'];
echo"Memory usage before collection:
".$gcStatus['memoryUsageBefore'];
echo"Memory usage after collection:".$gcStatus['memoryUsageAfter'];
10) PHP CLI Lint Enhancements: Simultaneous Linting of Multiple Files
PHP 8.3 now allows concurrent linting of multiple files in a single CLI process, streamlining syntax error-checking for improved efficiency in developer workflows.
bash
php -l file1.php file2.php file3.php
php
$constantName = 'THE_CONST';
$memberName = 'FirstMember';
echo MyClass::{$constantName};
echo MyEnum::{$memberName}->value;

Deprecations and Changes in PHP 8.3
1) unserialize(): E-NOTICE to E-WARNING
In PHP 8.3, the unserialize() function behavior has been modified. Error conditions, previously triggering notices (E_NOTICE), now generate warnings (E_WARNING). This includes syntax errors and custom __unserialize handler issues.
class Test {
public function __unserialize(array $data) {} // Does not return anything
}
2) get_class() and get_parent_class() changes
In PHP's recent deprecations, functions like `get_class` and `get_parent_class` are moving towards single-signature usage for improved consistency and readability. These functions, when invoked without parameters, return the name of the class in context.
php
class MyException extends InvalidArgumentException {
public function __construct() {
get_class($this);// "MyException"
get_parent_class($this);// "InvalidArgumentException"
}
}
In PHP 8.3, using get_class and get_parent_class functions without parameters is deprecated. PHP 9.0 will eliminate this, resulting in ArgumentCountError if $object parameter is not provided.
3) HTML Highlight Tag Changes
In PHP 8.3, syntax highlighting functions (highlight_file and highlight_string) generate HTML output enclosed within <pre><code></code></pre> tags, improving code legibility and HTML standards adherence.
php
$code=file_get_contents
(‘example.php’);
echo highlight_string($code, true);
4)Granular DateTime Exceptions
In PHP 8.3, specialized Exception and Error classes for date-related issues provide detailed error information, improving precision in reporting and facilitating efficient resolution of date-related errors for developers.
try {
// DateTime-related operation
} catch (\DateTimeException $e) {
// Handle DateTime-specific exception
} catch (\Exception $e) {
// Handle other exceptions
}
