Bug #72925 [NEW]: sqlsrv_fetch_object calls custom class constructors in static context

From: zburke at hshsl dot umaryland dot edu Operating system: Windows Server 2012 R2 PHP version: 7.0.10 Package: MSSQL related Bug Type: Bug Bug description:sqlsrv_fetch_object calls custom class constructors in static context Description: ------------ When a custom classname is passed to sqlsrv_fetch_object, the constructor is called in a static context, causing an error if it does anything with $this. This is inconsistent with the context used by PDO and Mysqli drivers. The problem occurs with driver version SQLSRV40.EXE under IIS 8.5. If you stick a print_r(debug_backtrace()) in the __construct() method of the custom class, you can see its type is '::' with sqlsrv_fetch_object instead of '->' for PDO->fetchObject or mysqli_fetch_object. Test script: --------------- <?php class Foo { protected $foo = null; public function __construct() { $this->foo = "bar"; } } $conn = sqlsrv_connect( 'HOSTNAME', ["Database"=> 'DATABASE', "UID"=> 'USERNAME', "PWD"=>'PASSWORD']); $stmt = sqlsrv_query($conn, "SELECT * FROM SOME_TABLE"); try { while ($obj = sqlsrv_fetch_object($stmt, 'Foo')) ; } catch (Error $e) { print_r($e); } Expected result: ---------------- There should be no output. Actual result: -------------- Error Object ( [message:protected] => Using $this when not in object context [string:Error:private] => [code:protected] => 0 [file:protected] => W:\path\to\wwwroot\test\db.php [line:protected] => 6 [trace:Error:private] => Array ( [0] => Array ( [function] => __construct [class] => foo [type] => :: [args] => Array ( ) ) [1] => Array ( [file] => W:\path\to\wwwroot\test\db.php [line] => 12 [function] => sqlsrv_fetch_object [args] => Array ( [0] => Resource id #3 [1] => foo ) ) ) [previous:Error:private] => ) -- Edit bug report at https://bugs.php.net/bug.php?id=72925&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72925&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72925&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72925&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72925&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72925&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72925&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72925&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72925&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72925&r=support Expected behavior: https://bugs.php.net/fix.php?id=72925&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72925&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72925&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72925&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72925&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72925&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72925&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72925&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72925&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72925&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72925&r=mysqlcfg
