Edit report at https://bugs.php.net/bug.php?id=79811&edit=1 ID: 79811 User updated by: buschmann at nidsa dot net Reported by: buschmann at nidsa dot net Summary: Script stops and delivers incomplete web page Status: Not a bug Type: Bug Package: PostgreSQL related Operating System: Windows Server 2019 64bit PHP Version: 8.0.0alpha2 Block user comment: N Private report: N New Comment: In my case this does not throw a fatal error. Have you tested my script under Windows? I have error_log enabled, E_ALL. In the error log I only get 1 line per call as: [09-Jul-2020 15:35:53 Europe/Berlin] PHP Warning: Undefined variable $rSOrder in N:\cpsdev\cps\cps_pg\hbtest.php on line 34 and then nothing more. I have tried it on the same machine with php 7.4.8 and get multiple lines of [09-Jul-2020 15:28:58 Europe/Berlin] PHP Notice: Undefined variable: rSOrder in N:\cpsdev\cps\cps_pg\hbtest.php on line 34 [09-Jul-2020 15:28:58 Europe/Berlin] PHP Warning: pg_fetch_assoc() expects parameter 1 to be resource, null given in N:\cpsdev\cps\cps_pg\hbtest.php on line 34 ... but the script terminates and shows all content in browser (view source).

If you do not see the error message, you need to look at your error handlers and your error related ini settings (do you have error_reporting=E_ALL? Do you have at least one of display_errors=1 or enabled logging? If you are logging, did you check your log?) In any case, this is not a bug in PHP. ------------------------------------------------------------------------ [2020-07-09 13:24:29] buschmann at nidsa dot net I have condensed the original script to a short version (even missing the connection to the database).

This is supposed to throw a TypeError in PHP 8. This TypeError is apparently caught by your script (maybe by set_error_handler() or set_exception_handler()). At least for debugging purposes, you could rewrite @$fSOrder=pg_fetch_assoc($rSOrder); to $fsOrder = isset($rSOrder) ? pg_fetch_assoc($rSOrder) : []; or so. ------------------------------------------------------------------------ [2020-07-09 07:09:30] buschmann at nidsa dot net I have tried it with opcache disabled, same error: The Zend OPcache extension is installed but not active The code comes from the php 4 era and has no explicit exception handling. The variable $rSOrder is only declared inside of this function as global and not set before. It should be easyly reproducable by declaring the function, calling the loop with dummy echos and some dummy echos after the loop. The core problem is that the script stops processing (different from 7.x.y). ------------------------------------------------------------------------ [2020-07-08 16:46:56] cmb@php.net > The call is probably throwing a TypeError, but something in your > error/exception handling setting eats it. That's quite likely. However, to exclude any potential OPcache issues, please run the script with OPcache disabled. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
