PHP mysqli_query won't execute - php

Question

I'm trying to write my first basic PHP RESTful API - I managed to get it working on my local machine using MAMP. But when I uploaded to hosting server, it doesn't want to work.
Code below - I've added some ECHO's in there to make sure things are working along the way. It seems like we're all good up until the $result=mysqli_query.
<?php
//header('Content-type:application/json');
// Connect to db
$con = mysqli_connect("HOSTNAME","USER","PASSWORD","DATABASE");
echo "Database: ";
// Check connection
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
echo "Connected successfully";
echo "<br><br>";
// Get value from url
$bid = $_GET['bid'];
echo "BID: ";
echo $bid;
echo "<br><br>";
// Define Query
$sql = "SELECT id, bandname, members, bio, songlist FROM bands WHERE id='$bid'";
echo "SQL Query: ";
echo $sql;
echo "<br><br>";
// Run Query
$result = mysqli_query($con, $sql);
echo "Result: ";
print_r($result);
echo "<br><br>";
// Put Query result into array
$result_array = mysqli_fetch_array($result, MYSQLI_ASSOC);
echo "Result Array: ";
print_r($result_array);
echo "<br><br>";
// Encode array as JSON and output
echo "JSON: ";
echo json_encode($result_array);
?>
The url I'm entering is http://bandsly.com/api.php?bid=1 and this is the output I'm getting in the browser...
Database: Connected successfully
BID: 1
SQL Query: SELECT id, bandname, members, bio, songlist FROM bands WHERE id='1'
Result:
Result Array:
JSON: null
When I manually run the query SELECT id, bandname, members, bio, songlist FROM bands WHERE id='1' in the database (PHPmyadmin), it works fine and I get 1 row returned with the correct values.
The manual db query result:

Any help would be most appreciated!!
*****EDIT*****
OK, i think i found the issue... My "successfully Connected" wasn't written correctly, and always came back looking good. It looks like after fixing that, i have db connection issues.
I'm going to go look up the db connection settings and try and fix that.
Thanks all for your help!

Answer 1

Your code seems to be ok on my localsystem http://www.awesomescreenshot.com/image/494275/c6c255cd6924d07196076b32489489de. There should be a connection problem . so you can do some try to check connection like
check the details in
// Connect to db
$con = mysqli_connect("HOSTNAME","USER","PASSWORD","DATABASE");
and then you can try to ping database
/* check connection */
if ($con->connect_errno) {
printf("Connect failed: %s\n", $con->connect_error);
exit();
}
/* check if server is alive */
if ($con->ping()) {
printf ("Our connection is ok!\n");
} else {
printf ("Error: %s\n", $con->error);
}

Your all code is correct, I have tested in my local just change your
HOSTNAME like "localhost", USER like "root", PASSWORD like "your password", DATABASE like "YOUR DATABASE NAME".
$con = mysqli_connect("HOSTNAME","USER","PASSWORD","DATABASE");
