Cannot Create Database PHP - php

Question

I am beginning to create my own Interface to use with MySql though I cannot seem to create a database with the code I have at the bottom. Everything else works also i can echo out the $ObtainDatabase variable to see that it does have a value stored. Any suggestions would be great.
<?php
session_start();
//define connection
$conn = new mysqli('localhost', 'over_watch','XXXXXXx','billing');
//Variables
$UserEmail = $_SESSION['email'];
$MysqlUserDataBaseCreate = $_POST['create_database'];
//CheckIfUserExists
$SeeIfUserExist = $conn->prepare("SELECT (email) FROM database_users WHERE email= ?;");
$SeeIfUserExist->bind_param('s',$UserEmail);
$SeeIfUserExist->execute();
$SeeIfUserExist->bind_result($ObtainedEmail);
$SeeIfUserExist->store_result();
$SeeIfUserExist->fetch();
$RowsReturnedFromPreparedStatment = $SeeIfUserExist->num_rows();
if($RowsReturnedFromPreparedStatment < 1){
$InsertIntoDatabase = $conn->prepare("INSERT INTO database_users(email,check_if_created) VALUES(?,?);");
$InsertIntoDatabase->bind_param('ss',$UserEmail,$MysqlUserDataBaseCreate);
$InsertIntoDatabase->execute();
$SelectDatabaseToCreate = $conn->prepare(" SELECT (check_if_created) FROM database_users WHERE email = ?;");
$SelectDatabaseToCreate->bind_param('s', $UserEmail);
$SelectDatabaseToCreate->execute();
$SelectDatabaseToCreate->bind_result($ObtainDatabase);
$SelectDatabaseToCreate->fetch();
$CreateDatabase = "CREATE DATABASE $ObtainDatabase ;";
$conn->query($CreateDatabase);
}else{
echo 'user permitted to one database';
}
?>

Can you try this Code.
Details about this error can be found in the mysql docs. Reading those details makes it clear that the result sets of a prepared statement execution need to be fetched completely before executing another prepared statement on the same connection.
Here is the doc where you can refer
<?php
session_start();
//define connection
$conn = new mysqli('localhost', 'over_watch','XXXXXXx','billing');
//Variables
$UserEmail = $_SESSION['email'];
$MysqlUserDataBaseCreate = $_POST['create_database'];
//CheckIfUserExists
$SeeIfUserExist = $conn->prepare("SELECT (email) FROM database_users WHERE email= ?;");
$SeeIfUserExist->bind_param('s',$UserEmail);
$SeeIfUserExist->execute();
$SeeIfUserExist->store_result();
$SeeIfUserExist->bind_result($ObtainedEmail);
$SeeIfUserExist->store_result();
$SeeIfUserExist->fetch();
$RowsReturnedFromPreparedStatment = $SeeIfUserExist->num_rows();
if($RowsReturnedFromPreparedStatment < 1){
$InsertIntoDatabase = $conn->prepare("INSERT INTO database_users(email,check_if_created) VALUES(?,?);");
$InsertIntoDatabase->bind_param('ss',$UserEmail,$MysqlUserDataBaseCreate);
$InsertIntoDatabase->execute();
$InsertIntoDatabase->store_result();
$SelectDatabaseToCreate = $conn->prepare(" SELECT (check_if_created) FROM database_users WHERE email = ?;");
$SelectDatabaseToCreate->bind_param('s', $UserEmail);
$SelectDatabaseToCreate->execute();
$SelectDatabaseToCreate->store_result();
$SelectDatabaseToCreate->bind_result($ObtainDatabase);
$SelectDatabaseToCreate->fetch();
$CreateDatabase = "CREATE DATABASE $ObtainDatabase ;";
$conn->query($CreateDatabase);
}else{
echo 'user permitted to one database';
}
?>
