Editing PHP (section)

==== Example ====
The following is a basic example of [[object-oriented programming]] in PHP&nbsp;8:

<syntaxhighlight lang="php" line>
<?php

abstract class User
{
    protected string $name;

    public function __construct(string $name)
    {
        // make first letter uppercase and the rest lowercase
        $this->name = ucfirst(strtolower($name));
    }

    public function greet(): string
    {
        return "Hello, my name is " . $this->name;
    }

    abstract public function job(): string;
}

class Student extends User
{
    public function __construct(string $name, private string $course)
    {
        parent::__construct($name);
    }

    public function job(): string
    {
        return "I learn " . $this->course;
    }
}

class Teacher extends User
{
    public function __construct(string $name, private array $teachingCourses)
    {
        parent::__construct($name);
    }

    public function job(): string
    {
        return "I teach " . implode(", ", $this->teachingCourses);
    }
}

$students = [
    new Student("Alice", "Computer Science"),
    new Student("Bob", "Computer Science"),
    new Student("Charlie", "Business Studies"),
];

$teachers = [
    new Teacher("Dan", ["Computer Science", "Information Security"]),
    new Teacher("Erin", ["Computer Science", "3D Graphics Programming"]),
    new Teacher("Frankie", ["Online Marketing", "Business Studies", "E-commerce"]),
];

foreach ([$students, $teachers] as $users) {
    echo $users[0]::class . "s:\n";

    array_walk($users, function (User $user) {
        echo "{$user->greet()}, {$user->job()}\n";
    });
}
</syntaxhighlight>

This program outputs the following:

{{samp|Students:<br>
Hello, my name is Alice, I learn Computer Science<br>
Hello, my name is Bob, I learn Computer Science<br>
Hello, my name is Charlie, I learn Business Studies<br>
Teachers:<br>
Hello, my name is Dan, I teach Computer Science, Information Security<br>
Hello, my name is Erin, I teach Computer Science, 3D Graphics Programming<br>
Hello, my name is Frankie, I teach Online Marketing, Business Studies, E-commerce|style=padding-left:0px; overflow-x: hidden; word-wrap: break-word;}}
