Quick correction, the code for getting all parent classes below has a "typo", you need to reset the $class variable to the parent class instance, otherwise it just endlessly loops:
$class = new ReflectionClass('classname');
$parents = array();
while ($parent = $class->getParentClass()) {
$parents[] = $parent->getName();
$class = $parent;
}
echo "Parents: " . implode(", ", $parents);

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