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
/**
* 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.
