Cannot create new MySQL database in php - php

I am having issues trying to create a new MySQL database in php,
my code is:
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = ‘somepassword’;
$conn = new mysqli($dbhost, $dbuser, $dbpass);
if(!$conn->connect_error )
{
die('Could not connect: %s' . $conn->connect_error);
}
echo "Connected successfully\n";
$sql = "CREATE DATABASE TUTORIALS2";
if($conn->query($sql)===TRUE){
echo "Created the database\n";
}
else {
echo "Failed to create the database".$conn->error;
}
//Close the database
$conn->close();
?>
MySQL connects fine but it won't allow me to create a new database. Not a clue what I'm doing wrong here. Any pointers would be greatly appreciated!

Second Edit:
I somehow missed this, apologies.
You have a mistake here:
if(!$conn->connect_error )
should be
if($conn->connect_error )
see here http://php.net/manual/en/mysqli.connect-error.php
Edit:
run this query SHOW GRANTS FOR 'root'#'localhost'; either from php or from PhpMyAdmin or similar and see if the user root has the privilege to create databases.
More here http://dev.mysql.com/doc/refman/5.0/en/show-grants.html
First of all you need to enable error_reporting and second you have some bad quotes on this line
$dbpass = ‘somepassword’;
replace like this
$dbpass = 'somepassword';

i need to connect a php MyAdmin MySQL database using php on MacOSX, but it cannot connect

here is the code that I am using:
$dbhost = "localhost:8080";
$dbuser = "root";
$dbpass = "";
$dbname = "test";
$conn = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);
if(! $conn){
die('Could not connect:'. mysql_error());
}
else{
echo "Connected Successfully";
}
?>
when I use include or require_once, I never get the echo "Connected successfully" I always receive the error.
This is for a university project, and in uni the windows computers connect right away, using the same code.
since i am using MacOSX is there anything i need to do?
My server is also running on bitnami MAMP

Upgrading from php5 to php7 having trouble running scripts [duplicate]

This question already has answers here:
Why shouldn't I use mysql_* functions in PHP?
(14 answers)
Closed 5 years ago.
I wonder if someone can help. I gave up web programming about 3 years ago. Since returning to programming about a week ago I realize I have forgotten quite a lot and so much has changed.
I signed on to a deal with php7 but my code is php5 and when I came to running my scripts nothing really works.
For example I couldn't even connect to the database. My database connection file for php5 was
<?php
$db_host = "localhost";
// Place the username for the MySQL database here
$db_username = "db_username_here";
// Place the password for the MySQL database here
$db_pass = "db_password_here";
// Place the name for the MySQL database here
$db_name = "name_of_database_here";
// Run the actual connection here
mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("$db_name") or die ("no database");
?>
I spoke to the server company and they told me everything has changed and to get my code compatible with php7. They then helped me get my database connected by giving me a sample file of how it should be which is this code.
<?
/* DATEBASE CONFIGURATION */
$dbHost = "ip Address";
$dbName = "name_of_database_here"; // Database name
$dbUser = "db_username_here"; // Database user
$dbPasswd = "db_password_here"; // Database password
function dbConnect(){
global $dbHost, $dbUser, $dbPasswd, $dbName;
mysql_connect( $dbHost, $dbUser, $dbPasswd ) or error( mysql_error() );
mysql_select_db( $dbName );
}
?>
I have always run my database $dbHost from localhost so I have guessed that because they haven't done the connection as localhost and done it as gobal with an ip address I have figured that the database is not on the same server as the website.
I then came to my database scripts for running from the browser to phpmyadmin and they also didnt work. Here is my database script php5.
<?php
require "connect_to_mysql.php";
$sqlCommand = "CREATE TABLE admin (
id int(11) NOT NULL auto_increment,
username varchar(24) NOT NULL,
password varchar(24) NOT NULL,
last_log_date date NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY username (username)
) ";
if (mysql_query($sqlCommand)){
echo "Your admin table has been created successfully!";
} else {
echo "CRITICAL ERROR: admin table has not been created.";
}
?>
I was wondering if someone could give me some advice on why the script isn't running
Many thanks, Gary
mysql_connect is removed from php7.
instead of that you can use either mysqli or pdo
example with mysqli
<?php
$servername = "localhost";
$username = "username";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
example with pdo
<?php
$servername = "localhost";
$username = "username";
$password = "password";
try {
$conn = new PDO("mysql:host=$servername;dbname=myDB", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}

MySQL and PHP connection failing

I have an issue with PHP script not connecting to MySQL database. Below code always generates error:
$dbconn = #mysql_connect('SFDC1', '<username>', '<password>');
if (!$dbconn)
{
die('Error connecting to DB!');
}
There is no issue if I connect to the database using MySQL workbench with same credentials. Issue only occurs during the communication between PHP and MySQL.
Any help on debug of this issue?
Try this one;
$dbhost = "localhost";
$dbuser = "username";
$dbpass = "pass";
$dbname = "DBname";
if(!#mysql_connect($dbhost,$dbuser,$dbpass)) {
echo "Cannot connect";
die();
} else
mysql_select_db($dbname);// or report();
Use this code to connect mysql.
<?php
$dbconn = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$dbconn ) {
die('Could not connect: ' . mysql_error());
}
?>

Connect To the MySQL Database

I have a table on PHPmyamdmin, and when i try to select it with the following code:
*<?php
//connect.php
session_start();
$server = 'localhost';
$username = 'zimmer';
$password = '';
$database = 'csgopit';
if(!mysql_connect($server, $username))
{
exit('Error: could not establish database connection');
}
if(!mysql_select_db($database))
{
exit('Error: could not select the database');
}
?>*
i get this error when i open the page in localhost:
Error: could not select the database
In the database i have 4 tables, one of them is users and i have manually added the user "zimmer" to it, i'm using this to create and experiment forum in my learning experiences, also, using this same code as a "connect.php" if i use it as for example on another file simply by using this line
using connect.php or include connect.php
would it work in a login or would it load only the user zimmer?
I started with PHP couple of days ago so sorry for the rookie question.
Try PDO.
$handler = '';
$server = 'localhost';
$username = 'zimmer';
$password = '';
$database = 'csgopit';
try {
$this->handler = new PDO('mysql:host='. $server .';dbname='. $database . ';charset=utf8', $username, $password);
} catch(PDOException $e) {
echo $e->getMessage();
die();
}
But you also mentioned you added the user "zimmer" to the users table. This is different than your $username you pass to connect to the database.
Did you set up a username and password to a database?

php syntax database connect

I'm trying to learn this stuff. Please be gentle.
Something is wrong here:
$dbhost = "localhost";
$dbname = "something_dbname";
$dbuser = "something_user";
$dbpass = "pwpwpwpw";
$dberror1 = "Could not connect to the database!";
$dbconnected = "you are connected!";
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ($dberror1);
$select_db = mysql_select_db($dbname . $dbconnected) or die ($dberror1);
where is my mistake? I want $dbconnected to show...
I can just as easily use
echo "hello";
it shows that I connect but I'm trying to get familiar with using multiple variables.
would this be better?
$dbhost = "localhost";
$dbname = "something_dbname";
$dbuser = "something_user";
$dbpass = "pwpwpwpw";
$dberror1 = "Could not connect to the database!";
$dbconnected = "you are connected!";
if ($mysqli = new mysqli($dbhost, $dbuser, $dbpassword, $dbname))
echo $dbconnected;
else die($dberror1);
Right now you are trying to connect to a database called something_dbnameyou are connected. The . concatenates variables into one string.
To fix your immediate problem, try this:
First, define $dbhost - I don't see it in your code.
Then change the last line to this:
$select_db = mysql_select_db($dbname) or die ($dberror1);
Then, just echo $dbconnected;
If you are not connected, the page will have called die, and will never reach the line that echos $dbconnected. If you are connected, the program will proceed to this next line and echo your success message.
Or you can do it more explicitly like this:
if ($select_db = mysql_select_db($dbname))
echo $dbconnected;
else die($dberror1);
To fix the bigger problem, DON'T use mysql_*. Read this for more information.
mysqli or pdo are far better options, and you can accomplish the same task easier, for instance, connecting to a db with mysqli is just:
$mysqli = new mysqli($dbhost, $dbuser, $dbpassword, $dbname);
Or you can do it procedural style, which is closer to your current code. The following snippet is from the php manual, on the page I linked in the comment below.
$link = mysqli_connect($dbhost, $dbuser, $dbpassword, $dbname);
if (!$link) {
die('Connect Error (' . mysqli_connect_errno() . ') '
. mysqli_connect_error());
}
echo 'Success... ' . mysqli_get_host_info($link) . "\n";
mysqli_close($link);
I'd strongly recommend using PDO. The connection string is similar and can be done using:
// I do not see $dbhost defined in your code. Make sure you have it defined first
try {
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo $dbconnected; // will print out the connection success message
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
