La función ReflectionExtension::getClasses() es una función incorporada en PHP que se utiliza para devolver una lista de clases de la extensión especificada. Si no se especifican clases, se devuelve una array vacía.
Sintaxis:
array ReflectionExtension::getClasses( void )
Parámetros: Esta función no acepta ningún parámetro.
Valor devuelto: esta función devuelve una lista de clases de la extensión especificada.
Los siguientes programas ilustran la función ReflectionExtension::getClasses() en PHP:
Programa_1:
<?php // Defining an extension $A = 'DOM'; // Using ReflectionExtension() over the // specified extension $extension = new ReflectionExtension($A); // Calling the getClasses() function $B = $extension->getClasses(); // Getting the list of classes var_dump($B); ?>
