Problem is in the function disp_invokeex() in file com_wrapper.c the var zarg declared in the for loop to catch parameters is overwriten every time, so all parameters have the value of the last one. The reason why it happened on some functions and not another depends of the compilation. We had here a random bug !! the solution is to replace this code (in disp_invokeex() in file com_wrapper.c) ///////////////////////////bugged code///////////////////// params = (zval ***)safe_emalloc(sizeof(zval **), pdp->cArgs, 0); for (i = 0; i < pdp->cArgs; i++) { VARIANT *arg; zval *zarg; arg = &pdp->rgvarg[ pdp->cArgs - 1 - i]; trace("alloc zval for arg %d VT=%08x\n", i, V_VT(arg)); ALLOC_INIT_ZVAL(zarg[i]); php_com_wrap_variant(zarg, arg, COMG(code_page) TSRMLS_CC); params[i] = &zarg; } /////////////////////////////////////////////////////// by this one : ////////////////////correct code///////////////////// params = (zval ***)safe_emalloc(sizeof(zval **), pdp->cArgs, 0); for (i = 0; i < pdp->cArgs; i++) { VARIANT *arg; zval **zarg= NULL; zarg=(zval **)safe_emalloc(sizeof(zval *), pdp->cArgs, 0); arg = &pdp->rgvarg[ pdp->cArgs - 1 - i]; trace("alloc zval for arg %d VT=%08x\n", i, V_VT(arg)); ALLOC_INIT_ZVAL(zarg[i]); php_com_wrap_variant(zarg[i], arg, COMG(code_page) TSRMLS_CC); params[i] = &zarg[i]; } ///////////////////////////////////////////////////////// Hope you'll correct for the next version ! ------------------------------------------------------------------------ [2004-12-09 18:24:39] jeanpierre dot vincent at gmail dot com Description: ------------ For some events of the IE browser, parameters given take value 0 and are of boolean type. For example : BeforeNavigate2, BeforeNavigate and CommandStateChange, whereas events like DocumentComplete work fine. Here is the example code from http://www.php.net/com-event-sink, which I simply added BeforeNavigate2. Launch it from a browser or CLI. Reproduce code: --------------- class IEEventSinker { var $terminated = false; // just after Browser understands he has to navigate function BeforeNavigate2(&$pDisp, &$url, &$Flags, &$TargetFrameName, &$PostData, &$Headers, &$Cancel) { foreach(func_get_args() as $id => $valeur) { // if the problem occurs ... if($valeur == 0) print $id.' = '.$valeur.' of type '.variant_get_type($valeur)."\n"; } // if the problem doesnt, $url is filled if($url != 0) echo "you'll navigate on $url\n"; } // when all objects of page are loaded function DocumentComplete(&$dom, $url) { echo "Document $url complete\n"; } // when closing browser function OnQuit() { echo "Quit!\n"; $this->terminated = true; } } $ie = new COM("InternetExplorer.Application"); // note that you don't need the & for PHP 5! $sink = new IEEventSinker(); com_event_sink($ie, $sink, "DWebBrowserEvents2"); $ie->Visible = true; $ie->Navigate("http://www.php.net";); while(!$sink->terminated) { com_message_pump(4000); } $ie = null; Expected result: ---------------- you'll navigate on http://www.php.net/ Document http://www.php.net/ complete Quit! Actual result: -------------- 0 = 0 of type 11 1 = 0 of type 11 2 = 0 of type 11 3 = 0 of type 11 4 = 0 of type 11 5 = 0 of type 11 6 = 0 of type 11 Document http://www.php.net/ complete Quit! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31040&edit=1
