Edit report at https://bugs.php.net/bug.php?id=78421&edit=1 ID: 78421 Updated by: cmb@php.net Reported by: martin dot koeditz at it-syn dot de Summary: Extension crash when no link identifier is given Status: Open Type: Bug Package: InterBase related Operating System: Linux PHP Version: 7.1.31 Block user comment: N Private report: N New Comment: > If you have to enter a link, the documentation has to be > editted. It's not a documentation issue; rather the implementation would have to be changed, but that would constitute a BC break. Anyhow, this issue has basically been mentioned in the removal RFC: <https://wiki.php.net/rfc/deprecate-and-remove-ext-interbase#what_is_broken_about_it> Previous Comments: ------------------------------------------------------------------------ [2019-08-16 10:15:50] martin dot koeditz at it-syn dot de Description: ------------ Documentation says: If called without an argument, this function commits the default transaction of the default link. If you use the function without default link, the script crashes. Test script: --------------- $dbh = ibase_connect('10.1.7.100', 'sysdba', 'masterkey'); $query = ibase_prepare($dbh, "UPDATE TBL_USER SET USER_DISPLAY_NAME = 'Koeditz, Martin' WHERE USER_ID = 125"); try { $transaction = ibase_trans(); ibase_execute($query); ibase_commit($transaction); } catch(Exception $e) { ibase_rollback($transaction); die($e->getMessage()); } echo "Everything is fine!"; Expected result: ---------------- If you have to enter a link, the documentation has to be editted. The program should never crash if the argument is missed. Actual result: -------------- The script crashes.
