To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2006-07-05 21:13:04] mcboog at zonnet dot nl Forget everything above. Description: When accessing a multi-dim array from COM-object Apache2 crashes with error [Wed Jul 05 22:50:21 2006] [notice] Parent: child process exited with status 3221225477 -- Restarting. This error-code seems to be related with array access problems. When I use the COM-object with VBScript I can access the value of the multi-dim array with: multiArray(1,1), which should have an equivalent in PHP by $multiArray[1][1]. Reproduce code: <?php $obj = new COM('com_object'); $obj->function_call($multiArray); print $multiArray[1][1]; ?> Expected result: output value. Actual result: Apache crashes. ------------------------------------------------------------------------ [2006-07-05 09:06:21] mcboog at zonnet dot nl Is there a reason why there is still no reaction on my bug report? ------------------------------------------------------------------------ [2006-06-29 21:03:32] mcboog at zonnet dot nl Description: ------------ As noticed in two previous bug-reports (//http://bugs.php.net/bug.php?id=35956 & //http://bugs.php.net/bug.php?id=33108) there is a problem with retrieving a multi-dimensional array from a COM-object. This problem is addressed on the website of Zend (http://www.zend.com/manual/faq.com.php, question #2), but should be resolved in PHP5 (http://www.zend.com/manual/ref.com.php, Arrays and Array-style COM properties). Reproduce code: --------------- $obj = new COM('com.object.version'); $varIn = new Variant; $varOutSimple = new Variant; $varOutComplex = new Variant; $obj->internal_com_method($varIn, $varOutSimple, $varOutComplex) This method has te following definition (part of output of com_print_typeinfo($obj)): function internal_com_method( /* VT_I4 [3] [in] */ $varIn, /* VT_PTR [26] [in][out] --> VT_VARIANT [12] */ &$varOutSimple, /* VT_PTR [26] [in][out] --> VT_VARIANT [12] */ &$varOutComplex ) { /* Method internal_com_method } $varIn is just an integer. $varOutSimple is a single-dimension array, $varOutComplex is a double-dimension array. Calling NumberOfFields; 1. print $varOutSimple->NumberOfFields; 2. print $varOutComplex->NumberOfFields; Count 3. print count($varOutSimple); 4. print count($varOutComplex); Getting value with string as key 5. print $varOutSimple['key']; 6. print $varOutComplex['key']; Doing foreach: 7. foreach ($varOutSimple as $key => $value) { print $value; } 8. foreach ($varOutComplex as $key => $value) { print $value; } Expected result: ---------------- 1. output 11 2. output 52 3. output 11 4. output 52 5. output $value 6. output $value 7. output $value 8. output $value Actual result: -------------- 1. output 11 2. Error: Uncaught exception 'com_exception' with message 'this variant has no properties'. 3. output 1 (irrelevant, works at 5. with direct string-key access) 4. output 52 5. output $value 6. Apache (Apache/2.0.55 (Win32) ) crashes 7. Error: Uncaught exception 'Exception' with message 'Object of type variant did not create an Iterator' 8. Error: Can only handle single dimension variant arrays (this array has 2) & (NB!) Uncaught exception 'Exception' with message 'Object of type variant did not create an Iterator' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37965&edit=1
