trouble connecting to dashDB on BlueMix - php

Question

Here is my code of my .php app connecting to dash-DB instance
//parse VCAP_SERVICES Environment variable
$vcap_services = $_ENV["VCAP_SERVICES"];
$services_json = json_decode($vcap_services,true);
$sqldb = $services_json["dashDB"];
if (empty($sqldb)) {
echo "No sqldb service instance is bound. Please bind a sqldb service instance";
return;
}
//Get Credentials object (db,host,port,username,password)
$sqldb_config = $services_json["dashDB"][0]["credentials"];
$conn_string = "DRIVER={IBM DB2 ODBC DRIVER};DATABASE=".
$sqldb_config["db"].
";HOSTNAME=".
$sqldb_config["host"].
";PORT=".
$sqldb_config["port"].
";PROTOCOL=TCPIP;UID=".
$sqldb_config["username"].
";PWD=".
$sqldb_config["password"].
";";
$conn = db2_connect($conn_string, '', ''); //db connection
$sql = "SELECT * FROM BX1_USERS WHERE Username ='$username'";
$foundElements = 0;
if ($conn) {
$stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));
//lLINE 44 that the output.txt fiel referres to starts here
while ($row = db2_fetch_assoc($stmt)) {
$dbusername = $row['Username'];
$dbpassword = $row['Password'];
$dbfirstname = $row['FirstName'];
$dblastname = $row['LastName'];
$foundElements = 1;
}
}
print $foundElements;
echo "<br>";
print $sql;
echo "<br>";
if ($foundElements == 1){
/// rest of my code here
I tested the printed $sql in the database console and it works just fine.. .. but still $foundElements = 0 ...
I get this error in the recent logs file:
"
PHP Warning: db2_fetch_assoc() expects parameter 1 to be resource, boolean given in /home/vcap/app/www/login.php on line 44,
"
I even added this to the code:
print $sqldb_config["db"];
echo "<br>";
print $sqldb_config["host"];
echo "<br>";
print $sqldb_config["port"];
echo "<br>";
print $sqldb_config["username"];
echo "<br>";
print $sqldb_config["password"];
and the page show the same exact values as in my VCAP.

Answer 1

after a few hours of banging my head against the wall I found an answer.
the code I was using was from a connection and queries I used on the IBM SQLDB...
and fro whatever reason I had to change it a little bit to work with IBM dashDB.
I had to change:
$stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));
to
$stmt = db2_exec($conn, $sql);
