sqlsrv_fetch_object calls custom class constructors in static context

[zburke]

Description:

When a custom classname is passed to sqlsrv_fetch_object, the constructor is called in a static context, causing an error if the constructors attempts to manipulate $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

    )
