#35339 [NEW]: COM "As" behaviour

From: amir at foresthc dot com Operating system: Windows PHP version: 5.0.5 PHP Bug Type: Feature/Change Request Bug description: COM "As" behaviour Description: ------------ In visual basic it is possible to declare a variable as a pointer to a certain type of object, but not instanciate it yet. I have run into a problem using a 3rd party COM library, where it is neccessary to pass such an empty pointer by ref to a method, in order to get an instance or another class. Reproduce code: --------------- // This code is not real, it's just to illustrate the problem: $factory = new COM('Example.Factory'); // Here we have several options, none of which work: $product = new VARIANT; $product = new COM('Example.Product'); variant_set_type($product, VT_EMPTY); // Whatever I have done in the previous lines, this method fails. If it gets an instance of an instance of an object - it fails. If it gets anything that is not of type Example.Product, it fails. $factory->Create_Product($product); Expected result: ---------------- Here is the "equivalent" VB code that works: Dim objFactory As Example.Factory Dim objProduct As Example.Product // Any of these would fail: Dim objProduct As New Example.Product Dim objProduct As Variant Sub Main() Set objFactory = new Example.Factory objFactory.Create_Product(objProduct) End Sub Actual result: -------------- The Create_Product method will fail if it does not recieve the equivalent of the line: "Dim objProduct As Example.Product". Which as far as I can understand, is not possible to supply it with at this point. -- Edit bug report at http://bugs.php.net/?id=35339&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35339&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35339&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35339&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35339&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35339&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35339&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35339&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35339&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35339&r=support Expected behavior: http://bugs.php.net/fix.php?id=35339&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35339&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35339&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35339&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35339&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35339&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35339&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35339&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35339&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35339&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35339&r=mysqlcfg
