#30690 [Opn]: Resource handle from ibase_execute becomes invalid after return

ID: 30690 User updated by: kobaz at kobaz dot net Reported By: kobaz at kobaz dot net Status: Open Bug Type: InterBase related Operating System: Linux 2.6.5 PHP Version: 4.3.9 New Comment: Er, and of course add the extra global variable, but you get the point. Previous Comments: ------------------------------------------------------------------------ [2005-02-09 20:32:36] kobaz at kobaz dot net I have a workaround for this bug: $PQUERY = array(); $curpquery = 0; function DB_PQuery ($sql, $data) { global $PQUERY, $conn; $PQUERY[$curpquery] = ibase_prepare($conn, $sql); $result = ibase_execute($PQUERY[$curpquery], $data); $curpquery++; return $result; } I agree with the previous poster that the result from prepare being destroyed after it goes out of scope is very inconsistant with the rest of the database interfaces for php and makes coding for interbase awkward. ------------------------------------------------------------------------ [2005-02-09 18:16:08] danielc@php.net While this behavior may be intentional on your part, I strongly request it be changed. 1) No other DBMS extension in PHP does this. 2) This makes writing programs using ibase very difficult. 3) This makes it impossible to write abstraction packages, such as PEAR DB (which I'm the lead of). ------------------------------------------------------------------------ [2004-11-07 14:21:36] abies@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php When $prepare goes out of scope, it is cleaned up along with all the resources that depend on it. That includes any results that it created. ------------------------------------------------------------------------ [2004-11-05 02:16:40] kobaz at kobaz dot net Description: ------------ Resource handle from ibase_execute becomes invalid after return Reproduce code: --------------- $conn = ibase_connect('localhost:db', 'SYSDBA', 'pass'); function DB_PQuery ($sql, $data) { global $conn; $prepare = ibase_prepare($conn, $sql); $result = ibase_execute($prepare, $data); // $A = ibase_fetch_assoc($result); // uncommenting this will show resource is valid here // print_r($A); // after this function returns, the return value is no longer a valid resource return $result; } $result = DB_PQuery("SELECT * FROM testing WHERE a = ?", '1'); $A = ibase_fetch_assoc($result); // fails with: invalid statement handle print_r($A); Expected result: ---------------- The ibase_fetch_assoc should be successful after DB_PQuery returns. Actual result: -------------- Before DB_PQuery returns, $result is a valid resource handle that can be used with ibase_fetch_assoc successfully. After DB_PQuery returns, the return value is not a valid resource handle despite that nothing in the script has modified it. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30690&edit=1
