PHP unable to connect to SQL Server using PDO- exception - php

Question

Im trying to connect php to SQL server driver using below:
It works fine for MYSQL., but not for SQL Server.
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$data = json_decode(file_get_contents('php://input'), true);
if(!empty($data)):
header('Content-Type:text/plain');
$hostname = '10.8.8.9';
$username = 'siddharth';
$password = '1234';
$dbname = 'AirportFootfall';
$mssqldriver = '{SQL Server}';
//$dbh = new PDO("mssql:host=$hostname;dbname=AirportFootfall", $username, $password);
//$dbh = new PDO("sqlsrv:Server=10.16.34.90;Database=AirportFootfall", $username, $password);
//$dbh = new PDO("odbc:Driver=$mssqldriver;Server=$hostname;Database=AirportFootfall", $username, $password);
//$dbh = new PDO("odbc:Driver=$mssqldriver;Server=$hostname;Database=AirportFootfall", $username, $password);
//$dbh = new PDO("dblib:host=$hostname;dbname=AirportFootfall", $username, $password);
//$dbh = new PDO("dblib:host=$hostname;dbname=$dbname", $username, $password);
$dbh = new PDO("dblib:host=$hostname;dbname=$dbname", $username, $password);
$arraykey=array_keys($data);
$array=$data[$arraykey[0]];
try
{
$count = $dbh->exec('INSERT INTO RadioCon_Sensor_Raw_Data(version,visitorId,dwellTime,poiId,srId,zoneId,poiProximityConfidence,zoneProximityConfidence,poiPresenceConfidence,zonePresenceConfidence,normalizedTime) VALUES ("' . implode('", "', $array) . '")' ) or die(print_r($dbh->errorInfo(), true));
//echo $count;
$dbh = null;
echo 'Data Successfully inserted!!<br />';
}
catch(PDOException $e)
{
echo $e->getMessage();
}
endif;
?>
UPDATE: Have insatalled the pdo_dblib extension.
Im getting
Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in /var/www/html/RADIOLOCOUS/GMR/gmrsample_copy.php:14 Stack trace: #0 PDO->__construct('odbc:Driver={SQ...', 'siddharth', '1234') #1 {main} thrown in ....line 14
Any alternate way to connect apart from pdo
Im using Ubuntu 14.04 LAMP with php 5.5
My php_info says:
PDO drivers dblib, mysql

Answer 1

The documentation for PDO_DBLIB shows the following DSNs:
mssql:host=localhost;dbname=testdb
dblib:host=localhost;dbname=testdb
So I'd like to suggest this:
$dbh = new PDO("dblib:host=$hostname:1433;dbname=AirportFootfall", $username, $password);
You can test your connection this way:
<?php
header('Content-Type:text/plain');
$hostname = '10.8.8.9';
$username = 'siddharth';
$password = '1234';
$dbname = 'AirportFootfall';
try {
$dbh = new PDO("dblib:host=$hostname:1433;dbname=$dbname", $username, $password);
$sql = "SELECT 'It is working' AS name";
foreach ($dbh->query($sql) as $row) {
print $row['name'] . "\n";
}
} catch (PDOException $ex) {
print $ex->getMessage();
}
?>

It looks like the $mssqldriver var is commented... Did you try to uncomment?? If you look carefully the Connection statement use that var:
$dbh = new PDO("odbc:Driver=$mssqldriver;Server=$hostname;Database=AirportFootfall", $username, $password);
