Hello All, It seems to me that an instance of RecursiveIteratorIterator with ArrayObject has no effect when calling RecursiveArrayIterator::offsetUnset or RecursiveArrayIterator::offsetSet methods. But everything works fine when the iterator is created with a json_decoded - json_encoded array. I expect the same behavior of these two iterators, but maybe I am wrong. Any guidance would be appreciated. Test script: ---------------------------------- function example() { $array = array ( 'name' => 'text', 'items' => array ( '0' => array ( 'phrase' => 'text text', ), '1' => array ( 'phrase' => 'text text text', ), 'ctrl' => array( '0' => '1', ), ), ); $array_object = json_decode( json_encode( $array )); $iterator = new RecursiveIteratorIterator( new RecursiveArrayIterator( $array_object ), RecursiveIteratorIterator::CHILD_FIRST ); // comment these two lines and see the nice execution $array_object = new ArrayObject( $array, 0, "RecursiveArrayIterator" ); $iterator = new RecursiveIteratorIterator( $array_object->getIterator(), RecursiveIteratorIterator::CHILD_FIRST ); foreach( $iterator as $key => $value ) { $array_copy = $iterator->getInnerIterator()->getArrayCopy(); $keys = array_keys( $array_copy ); $numeric_keys = array_filter( $keys, 'is_numeric' ); if( count( $numeric_keys ) !== 0 && count( $keys ) == count( $numeric_keys ) + 1 ) { $ctrl = $array_copy['ctrl']; $iterator->getInnerIterator()->offsetUnset( 'ctrl' ); foreach( $iterator->getInnerIterator() as $ctrl_value => $value ) { if( in_array( $ctrl_value, $ctrl )) { $iterator->getInnerIterator()->getChildren()->offsetSet( 'ctrl', $ctrl_value ); } else { $iterator->getInnerIterator()->getChildren()->offsetSet( 'ctrl', '' ); } } // print_r( $iterator->getInnerIterator() ); } } print_r( object_to_array( $array_object )); // print_r( iterator_to_array( $iterator )); } // helper method function object_to_array( $object ) { if( ! is_array( $object ) && ! is_object( $object )) { return $object; } if( is_object( $object )) { $object = get_object_vars( $object ); } return array_map( __FUNCTION__, $object ); } example(); Expected result: -------------------------- [11-Mar-2013 18:24:48 UTC] Array ( [name] => text [items] => Array ( [0] => Array ( [phrase] => text text [ctrl] => ) [1] => Array ( [phrase] => text text text [ctrl] => 1 ) ) ) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
