Connecting SQL server DB to A PHP web application using Wamp - php

Question

I have searched through many posts trying to find an answer but get nowhere.
I am trying to establish a connection to and Sql Server DB through my PHP web application using WAMP.
What I have tried:
I downloaded the sql drivers for PHP 7 and 7.1 and tried them with the corresponding PHP versions
I made sure to restart all services after updating the php.ini file.
I haveinstalled the SQLSRV40.EXE and updated the php.ini with:
extension=php_pdo_sqlsrv_7_ts_x64.dll
extension=php_pdo_sqlsrv_7_nts_x64.dll
I did not though that even though these are added in the php.ini they were not in the php> php extentions list - not sure why
This is my code below allow with the error
<?php
$serverName="DESKTOP-0KNJ0KP";
$connectionInfo=array("Database"=>"SPMS_db",);
$conn=sqlsrv_connect($serverName,$connectionInfo);
if ($conn) {
echo "Connected.<br />";
} else {
echo "Connection failed.<br />";
die( print_r( sqlsrv_errors(), true));
}
?>
I have added context fro PHPinfo()

Answer 1

You have installed PDO_sqlsrv part of PHP Driver for SQL Server, but your code uses sqlsrv functions. You have two options:
install php_sqlsrv_ extensions to make these functions work or
rewrite your code to use PDO version of the driver
PHP code using PDO version of PHP Driver for SQL Server:
<?php
# Connection
$server = "DESKTOP-0KNJ0KP";
$database = "SPMS_db";
try {
$conn = new PDO( "sqlsrv:Server=$server;Database=$database", NULL, NULL);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
} catch( PDOException $e ) {
die( "Error connecting to SQL Server. ".$e->getMessage() );
}
# End
$conn = null;
?>

Connecting through PDO library (which is already installed in your server) is easier.
See PDO Book from PHP.NET: https://www.php.net/manual/en/ref.pdo-dblib.php
