Your conn
class property is not set. 您的conn
类属性未设置。
Before you call $stmt = sqlsrv_query($this->conn, $sql);
在调用$stmt = sqlsrv_query($this->conn, $sql);
you must set it up in sqlsrv_connect . 您必须在sqlsrv_connect中进行设置。
Try adding construct: 尝试添加构造:
public function __construct()
{
$this->conn = sqlsrv_connect($GLOBALS["serverName"], $GLOBALS["connectionInfo"]);

Hope it will help. 希望它会有所帮助。
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"]);
?>
