mysql_create_db — Create a MySQL database

Warning

This function was deprecated in PHP 4.3.0, and it and the entire original MySQL extension was removed in PHP 7.0.0. Instead, use either the actively developed MySQLi or PDO_MySQL extensions. See also the MySQL: choosing an API guide. Alternatives to this function include:

- mysqli_query()
- PDO::query()

### Description

mysql_create_db(string `$database_name`, resource `$link_identifier` = NULL): bool

mysql_create_db() attempts to create a new database on the server associated with the specified link identifier.

### Parameters

`database_name`

  The name of the database being created.

`link_identifier`

  The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() had been called with no arguments. If no connection is found or established, an `E_WARNING` level error is generated.

### Return Values

Returns `true` on success or `false` on failure.

### Examples

Example #1 mysql_create_db() alternative example

The function mysql_create_db() is deprecated. It is preferable to use mysql_query() to issue an sql `CREATE DATABASE` statement instead.

    <?php$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');if (!$link) {    die('Could not connect: ' . mysql_error());}$sql = 'CREATE DATABASE my_db';if (mysql_query($sql, $link)) {    echo "Database my_db created successfully\n";} else {    echo 'Error creating database: ' . mysql_error() . "\n";}?>

The above example will output something similar to:

    Database my_db created successfully

### Notes

> Note:

> For backward compatibility, the following deprecated alias may be used: mysql_createdb()

> Note:

> This function will not be available if the MySQL extension was built against a MySQL 4.x client library.
