Updated Problem: I'm trying to use PHP to add information into a SQL table if there is no errors, but I am not sure how to get it to fully working so that it'll show the errors and such. Where do I put the PHP code? Also where what language would I use to display the errors?

Updated PHP:
$sql="SELECT username, email FROM Profiles";
$result=mysqli_query($con,$sql);
if($result === false){
echo mysqli_error($con);
}else{
while($row = mysqli_fetch_array($result)){
$rows[] = $row;
foreach ($rows as $row) {
if($row['username'] == $_POST['username'] || $row['email'] == $_POST['email']){
//Error: "Username or Email already in use"
}else {
if($_POST['password'] == $_POST['password2']){
if (strpos($_POST['email'],'@') !== false) {
//INSERT INTO code?
}else{
//Error: "Please enter a valid email."
}
}else{
//Error: "Passwords do not match."
}
}
}
mysqli_close($con);
}
}
}else{
//Error code: "Please fill in all fields"
}
?>
