The code sample will show that var_dump() will print de "second" twice instead of once like in print_r(). This goes terribly wrong with large var_dumps with multiple recursion. print_r() needed 5MiB memory for my dump. and var_dump() needed more than the ini_set("memory_limit", "1G") I applied. Code for generating a big dump. class IndexController extends Zend_Controller_Action { public function indexAction() { var_dump($this->_helpers); } } Test script: --------------- <?php $array = array( 'first' => array(), ); $array['first']['second'] = &$array['first']; echo "<pre>\n"; var_dump($array); echo "\n\n"; print_r($array); echo "<pre>\n"; ?> Expected result: ---------------- <pre> array(1) { ["first"]=> &array(1) { ["second"]=> *RECURSION* } } Array ( [first] => Array ( [second] => Array *RECURSION* ) ) Actual result: -------------- <pre> array(1) { ["first"]=> &array(1) { ["second"]=> &array(1) { ["second"]=> *RECURSION* } } } Array ( [first] => Array ( [second] => Array *RECURSION* ) ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51445&edit=1
