<?php $data = array( 0 => array( 0 => 1, ), 1 => array( 0 => 2, ), 2 => array( 0 => 3, 1 => 4, 2 => 5, ), 3 => array( 0 => 6, ), 4 => array( 0 => 7, ), ); $it = new RecursiveArrayIterator(new RecursiveArrayIterator($data)); echo PHP_EOL, implode(iterator_to_array($it)); //745 instead of 1234567 echo PHP_EOL, implode(iterator_to_array($it, true)); //745 instead of 1234567 echo PHP_EOL ; foreach($it as $v) { echo $v ; }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
