您的conn類屬性未設置。

在調用$stmt = sqlsrv_query($this->conn, $sql); 您必須在sqlsrv_connect中進行設置。

嘗試添加構造： 

public function __construct()
{
    $this->conn = sqlsrv_connect($GLOBALS["serverName"], $GLOBALS["connectionInfo"]);
}

I have these two items in my php.ini file enabled:

extension=php_pdo_sqlsrv_53_ts.dll
extension=php_sqlsrv_53_ts.dll

Which is what I had before. Using Wamp Server. PHP 5.3.13 all the same as before. What else am I missing that is not allowing this to connect to the SQL server.

After connection file code.
<?php

$GLOBALS["serverName"] = "localhost";  
$GLOBALS["database"] = "SimpleUsers";  
$GLOBALS["uid"] = "root";
$GLOBALS["pwd"] = "";  
$GLOBALS["connectionInfo"] = array(
                                "Database"=>$GLOBALS["database"],
                                "UID"=>$GLOBALS["uid"],
                                "PWD"=>$GLOBALS["pwd"]);

$conn = sqlsrv_connect($GLOBALS["serverName"], $GLOBALS["connectionInfo"]);

?>
