Running SQL Query in PHP File - php

Question

I have established a connection with my SQL Database through Windows Authentication in my php file. However I'm not sure how the syntax will look if I wanted to display a simple SQL query such as (Select * from Media) on the php page that shows an entire table. I tried a few methods but it displayed a fatal error.
Here is my code for the php:
<?php
$serverName = "172.20.90.170,5050"; //serverName\instanceName
// Since UID and PWD are not specified in the $connectionInfo array,
// The connection will be attempted using Windows Authentication.
$connectionInfo = array( "Database"=>"TestDB");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
$version = mssql_query('SELECT * FROM MEDIA');
$row = mssql_fetch_array($version);
echo $row[0];
?>
Fatal Error:
Fatal error: Call to undefined function mssql_query()
This establishes a succesful connection but what would I need to change in my code for this query to run error free and display the required output?

Answer 1

It appears you are mixing two different API's (sqlsrv_ and mssql_).
If you're using sqlsrv_, then a simple statement could look like:
$connectionInfo = array( "Database" => "database", "UID" => "username", "PWD" => "password" );
$conn = sqlsrv_connect( "Server", $connectionInfo );
$stmt = "SELECT [column] FROM [table] WHERE [id] = ?";
$params = array( $id );
$query = sqlsrv_query( $conn, $stmt, $params );
if( $query === false ) {
print( print_r( sqlsrv_errors() ) );
}
while( $row = sqlsrv_fetch_array( $query, SQLSRV_FETCH_ASSOC )) {
echo $row['column'];
}
sqlsrv_close( $conn );

From what I understand, you're new to the PHP world, BUT, I advise you to use the PDO class. You will have more facility to do what you want.
Here's a sample using your data.
If you study, you can understand.
try
{
$connection = new PDO("sqlsrv:Server=172.20.90.170;Database=TestDB", "YOUR_USERNAME", "YOUR_PASSWORD");
$connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$connection->setAttribute(PDO::SQLSRV_ATTR_ENCODING, PDO::SQLSRV_ENCODING_SYSTEM);
}catch (Exception $e)
{
echo $e->getMessage();
die('Connection could not be established.<br />');
}
try
{
$sql = 'SELECT * FROM MEDIA';
$query = $connection->prepare($sql);
$query->execute();
$result = $query->fetchAll(PDO::FETCH_ASSOC);
}catch (Exception $e)
{
die('Cant fetch rows.');
}
foreach ($result as $r)
{
print_r($r); // do what you want here
}

As others says in the comments, you have two options:
1. Use sqlsrv_query
2. Install MSSQL support to PHP.
Sincerely, I prefer use mssql_* stack of functions. If you use ubuntu, you can install MSSQL support simply:
aptitude install php5-sybase
