88.4k views Asked by Robert Farb At 09 June 2015 at 15:34

I am using

Xampp version 3.2.1 with PHP version 5.6.8.
Microsoft Azure SQL server

GOAL

I am trying to create a web app that will access to my database, and be able to SELECT, INSERT, UPDATE and DELETE records.

PROBLEM

I cannot connect to the database server

ERROR

Fatal error: Call to undefined function sqlsrv_connect() in C:\xampp\htdocs\BLT\Employee_Database .php on line 25

CODE

<html>
<head>
    <Title>Employee Database</Title>
</head>
<body>
<form method="post" action="?action=add" enctype="multipart/form-data">
    Last name <input type="text" name="LastName" id="LastName"/></br>
    First name <input type="text" name="FirstName" id="FirstNamne"/></br>
    E-mail address <input type="text" name="Email" id="Email"/></br>
    User Id <input type="text" name="UserId" id="UserId"/></br>
    Password <input type="password" name="Password" id="Password"/></br>
    <input type="submit" name="submit" value="Submit"/>
</form>

<?php
$serverName = "jy4nij6vuy.database.windows.net,1433";
$connectionOptions = array("Database" => "robertfarb",
    "UID" => "robertFarb",
    "PWD" => "******");
$conn = sqlsrv_connect($serverName, $connectionOptions);

if ($conn === false) {
    die(print_r(sqlsrv_errors(), true));
}
?>

</body>
</html>

THIS IS WHAT I TRIED SO FAR

I have installed the Microsoft PHP for SQL drivers and followed all the instructions to load the driver, but it does not seem to be working!
I added the php_sqlsrv_56.ts.dll file to the extensions folder of PHP, and also the php_pdo_sqlsrv_56.ts.dll.
I also added the extension=php_sqlsrv_56.ts.dll line to the php.ini file.

Any help would be much appreciated!

Lea's answer should do the trick for you. It is very important that you download PHP 5.6 from the Web PI - https://www.microsoft.com/web/downloads/platform.aspx

Make sure to use IE when you download the Web PI to your machine.

Download Microsoft Drivers for PHP for SQL Server Windows (Link), It'll be a zip file after downloaded open the file
Extract the downloaded file in default PHP extension directory (Usually c:\php\ext , c:\xampp\php\ext)
To enable the SQLSRV driver, modify php.ini by adding the following line to the extension section. your PHP version and the extension/dll version should match you can refer to the below image. changing the filename as appropriate:

extension=php_sqlsrv_80_ts.dll

To enable the PDO_SQLSRV driver, the PHP Data Objects (PDO) extension must be available, either as a built-in extension or as a dynamically loaded extension.

extension=php_pdo_sqlsrv_80_ts.dll

Restart the Web server.

Please read the MS document Loading the Microsoft Drivers for PHP for SQL Server For Detailed Steps and more info

NOTE: REMEMBER TO LOAD THE DRIVER VERSION CORRESPONDING TO THE PHP VERSION REFER BELOW IMAGE

I followed Lea Tano guide and didn't work. I needed a fer more steps. At least for Windows7 (or for my system) there're some missing steps(ie those who don't have MSSQL Server installed in the same server/machine).

Here's how i made it work:

Follow Lea Tano guide to install SQLSRV 5.6 (or 5.3 or..)
Download and install the OBDC Driver 11 (msodbcsql.msi)
Download and install the SQL Server Native Client (sqlncli.msi file)
Check if installed (if not, download and install) Visual C++ Redistributable VS2012 Update4 (vcredist_x86.exe)

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://www.microsoft.com/en-us/download/details.aspx?id=20098

Step by Step

Download SQLSRV32.EXE (Microsoft Drivers for PHP for SQL Server) from: http://www.microsoft.com/en-us/download/details.aspx?id=20098
Choose path: C:\xampp\php\ext

enter image description here

Uncomment or Append extension = php_sqlsrv_56_ts.dll in php.ini
Restart Apache from XAMPP Control Panel (Stop/Start)

I tested it and it works 100%

You can find the most recent compiled binaries in the official Microsoft Git repository.
