ID: 46610 Updated by: jani@php.net Reported By: danil dot megrabjan at gmail dot com -Status: Open +Status: Feedback Bug Type: Reflection related Operating System: openSUSE11 PHP Version: 5.2.6 New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.

I calling method(getDataMeta) of class throw ReflectionMethod->invokeArgs(). In this method i call another method(getColMeta) of this class and print information about return value(EXPECTED RESULT) - it`s OK. When i getting this value in getDataMeta i printed dump of variable once more time(ACTUAL RESULT 1) - it`s BAD. After invokeArgs() i print dump(ACUTAL RESULT 2) of this variable one more(3!) time - it`s BAD as a second print. Different between this dump`s you may see bellow in expected and actual results. I "lost" one of item my array. In second,third times i have &UNKNOWN instead of my object. 10x! Reproduce code: --------------- /* calling */ $retval = $method->invokeArgs($object, $args); /* ACTUAL RESULT 1 */ debug_zval_dump($retval); /* for calling throw invokeArgs */ public function getDataMeta() { $retval = MetaData($this->getColMeta(), $this->getRowCount()); /* ACTUAL RESULT 2 */ debug_zval_dump($retval); } /* for getDataMeta */ public function getColMeta() { $retval = array(); foreach ($this->getBase()->q->fields['list'] as $q_field) { if ($this->getBase()->fields->key_exists($q_field['name'])) { $d_field = $this->getBase()->fields->items($q_field['name']); if (!empty($d_field->rusName) && $d_field->isVisible) { if (is_null($d_field->gridOrder)) { $d_field->gridOrder = 0; } $retval[MetaData::getColumnPosition(($d_field->gridOrder < 0) ? 0 : $d_field->gridOrder, $retval)] = new MetaColumn( $q_field['name'] ... ); } } } if (count($retval) > 0) { //ksort($retval); $retval = array_values($retval); } /* EXPECTED RESULT */ debug_zval_dump($retval); return $retval; } Expected result: ---------------- ========== EXPECTED RESULT = refcount(2){ [0]=> object(MetaColumn)#654 (5) refcount(1){ ["name"]=> string(10) "REGIST_NUM" refcount(2) ["label"]=> string(9) "Док.
