Here is a "replacement" for is_a that will additionally look both into the extended classes and in the implemented interfaces

<?php
/**
     * Check if a class extends or implements a specific class/interface
     * @param string $search The class or interface name to look for
     * @param string $className The class name of the object to compare to
     * @return bool
     */
    function IsExtendsOrImplements( $search, $className ) {
        $class = new ReflectionClass( $className );
        if( false === $class ) {
            return false;
        }
        do {
            $name = $class->getName();
            if( $search == $name ) {
                return true;
            }
            $interfaces = $class->getInterfaceNames();
            if( is_array( $interfaces ) && in_array( $search, $interfaces )) {
                return true;
            }
            $class = $class->getParentClass();
        } while( false !== $class );
        return false;
    }
?>

When you want to find all parents (parent, parent of parent, parent of parent's parent and so on) try:

<?php
$class = new ReflectionClass('whatever');

$parents = array();

while ($parent = $class->getParentClass()) {
    $parents[] = $parent->getName();
}

echo "Parents: " . implode(", ", $parents);
?>

ReflectionClass::getParentClass() can return a ReflectionClass object of the parent class or false if no parent.

(PHP Version 5.1.6)

When your class extends a parent class you maybe want the name
of them. Using getParentClass() is maybe a bit confusing. When
you want the name as string try the following.

<?php
$class = new ReflectionClass('whatever');

$parent = (array) $class->getParentClass();

if(array_key_exists('name', $parent))
{
    # name of the parent class
    $parent = parent['name'];
}
else
{
    # no parent class avaible
    $parent = false;
}
?>

When you turn getParentClass() to an array it will result either
array(0 => false) when no parent class exist or
array('name' => 'name of the parent class'). Tested on PHP 5.2.4
