Bug #75271 [NEW]: ODBC query result contains random memory blocks, source code

From: charlie at csdv dot co Operating system: Windows, MacOS PHP version: 7.1.9 Package: PDO ODBC Bug Type: Bug Bug description:ODBC query result contains random memory blocks, source code Description: ------------ Behavior exists in 5.5, 5.6, and 7.1. When querying a database via PDO ODBC, some fields are returning unexpected results which appear to be uninitialized memory, bits of the source PHP file that ran the script, other PHP files that were included, etc. I've run this same query via Golang and other GUIs and the correct data is returned. Example output: Array ( [0] => Array ( [body] => Lorem ipsum�/** * Finds the path to the file where the class is defined. * * @param string $class The name of the class * * @return string|false The path if found, false otherwise Since it's working as expected when querying via other languages/tools, I'm thinking the issue is within PDO and not the driver. Any direction on this issue would be much appreciated. Test script: --------------- $connection = new PDO("odbc:Driver=driver;Server=hostname;Database=dbname;Uid=uid;Pwd=pwd;"); $result = $connection ->query("SELECT body FROM posts WHERE id = 123") ->fetchAll(PDO::FETCH_ASSOC); print_r($result); -- Edit bug report at https://bugs.php.net/bug.php?id=75271&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75271&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75271&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75271&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75271&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75271&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75271&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75271&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75271&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75271&r=support Expected behavior: https://bugs.php.net/fix.php?id=75271&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75271&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75271&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75271&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75271&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75271&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75271&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75271&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75271&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75271&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75271&r=mysqlcfg
