Editing Constructor (object-oriented programming) (section)

=== PHP ===
In [[PHP]] version 5 and above, the constructor is a method named <code>__construct()</code> (notice that it's a double underscore), which the keyword <code>new</code> automatically calls after creating the object. It is usually used to automatically perform initializations such as property initializations. Constructors can also accept arguments, in which case, when the <code>new</code> statement is written, you also need to send the constructor arguments for the parameters.<ref name="php5cpnstructor"/>

<syntaxhighlight lang="php">
class Person
{
    private string $name;

    public function __construct(string $name): void
    {
        $this->name = $name;
    }

    public function getName(): string
    {
        return $this->name;
    }
}
</syntaxhighlight>

In PHP, a class is only allowed to declare a maximum of one constructor method. Static methods, factory classes or optional constructor arguments are some ways to facilitate multiple ways to create objects of a PHP class.
