Our product is running on LAMP(PHP) architecture. For MySQL operation PDO library has been used.
We are in the process of moving the product to a new Linux server.
On the new server we are facing MySQL query output related issue. At the end of the post I have listed the server configuration details of both the servers and the sample PHP program with the output.
It works fine in server 1 but when the same code moved to Server 2, the output is not correct.
Would appreciate any points to solve this problem
The following piece of code is tested and output is also given.
<?php
/*** mysql hostname ***/
$hostname = 'localhost';
/*** mysql username ***/
$username = 'ram';
/*** mysql password ***/
$password = 'tellmehow';
try {
$dbh = new PDO("mysql:host=$hostname;dbname=inhouse", $username, $password);
$sql = "SELECT first_name,last_name,user_id,email FROM users LIMIT 1";
$stmt = $dbh->prepare($sql,array(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => TRUE));
$stmt->execute();
$result = $stmt->fetch(PDO::FETCH_OBJ);
$stmt->closeCursor();
/*foreach($result as $key=>$val)
{
echo $key.' - '.$val.'<br />';
}*/
print_r($result);
$dbh = null;
}
catch(PDOException $e)
{
echo $e->getMessage();
}
?>
Output for server 1:
stdClass Object
(
[first_name] => super
[last_name] => admin
[user_id]=>1
=> ram@greynium.com
)
output for server 2:
stdClass Object
(
[first_name] => super
[last_name] => admin
[users] => ram@greynium.com
)
On server 2 I am not getting the output for field 'user_id' from the table 'users'.
For the field 'email' from 'users' table, it is displaying the name of the table itself (users). Not sure what is wrong.
The configuration of the servers are given below
