Cant connect php to mysql - php

Question

New to php and am connecting form attributes to php to connect to a godaddy mysql. Every attempt ends in a blank screen with no error messages. Is there any syntax errors the jump out? My sublime text wont register php syntax, but thats another problem for another time. I may need to call up godaddy support? the password has been removed for privacy.
<?php
$servername = "localhost";
$dbusername = "jaysenhenderson";
$dbpassword = "xxxxx";
$dbname = "EOTDSurvey";
$con = new mysqli ($servername, $dbusername, $dbpassword, $dbname);
mysql_select_db('EOTDSurvey', $con)
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo("Connected successfully");
$_POST['BI1']
$_POST['BI2']
$_POST['BI3']
$_POST['BI4']
$_POST['BI5']
$_POST['BI6']
$_POST['BI7']
$_POST['BI8']
$_POST['BI9']
$_POST['BI10']
$_POST['BI11']
$_POST['BI12']
$_POST['BI13']

$_POST['BI15']
$sql = "INSERT INTO Survey1(BI1)"

$sql = "INSERT INTO Survey1(BI14)"
$sql = "INSERT INTO Survey1(BI15)"
if ($conn->query<$sql) === TRUE) {
echo "IT FUCKING WORKS.";
}
else{

$conn->close();

Answer 1

please connect database like this...
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);
if (!$connection) {
die("Database connection failed: " . mysqli_error());
}
// 2. Select a database to use
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
die("Database selection failed: " . mysqli_error());
}
And Use mysqli_select_db instead of mysql_select_db
And insert semi-colon (;) after every line end according to php code standard.

Answer 2

There are a lot of issues with this code, as mentioned the mysqli_select_db issue. The $_POST['BIx'] will also cause errors because there is no semi-colon after each statement. You're missing a '(' on the line if ($conn->query<$sql) === TRUE) { not to mention that line will not work anyway because you're logically comparing a resource type (I think) to a string.
You're also never executing the insert statements. All around I seriously think you should practice PHP coding some more and read up on how to use mysqli properly: see here.

EDIT: You also have a closing PHP tag at the end of your script which is generally not a good idea as explained here
EDIT 2: Also using an IDE such as Netbeans is always a good idea as it can highlight syntax errors instead of asking SO to do it for you ;)
