How to Obtain Class Name in PHP?

Acquiring Class Name in PHP

In Java, the SimpleName for a class can be obtained using the MyClass.class.getSimpleName() syntax. In PHP, retrieving the class name for an object is possible using get_class(). However, accessing it directly from the class itself, like MyClass::className, requires a different approach.

PHP 5.5 and Later versions:

Starting from PHP 5.5, the ClassName::class syntax can be used to resolve class names. For example:

<code class="php">namespace Name\Space;

class ClassName {}

echo ClassName::class;</code>

This will output the class name as NameSpaceClassName.

PHP versions before 5.5:

For older versions of PHP, you can utilize the get_class() function, but this only works for objects. If you require a class name, consider using a dedicated class name constant, like:

<code class="php">class ClassName {
    const CLASS_NAME = 'ClassName';
}

echo ClassName::CLASS_NAME;</code>

Alternatively:

Another option is using static::class within class methods:

<code class="php">class ClassName {
    public function getNameOfClass() {
        return static::class;
    }
}

$obj = new ClassName();
echo $obj->getNameOfClass();</code>
