mysql_create_db
Create a MySQL database
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 and its related FAQ entry for additional information. Alternatives to this function include:
mysqli_query
|
PDO::query
|
bool mysql_create_db(string database_name,
resource link_identifier= =NULL);
mysql_create_db
attempts to create a new database on the server associated with
the specified link identifier.
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.
Returns true
on success or
false
on failure.
Example 6.9 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
For backward compatibility, the following deprecated alias may
be used: mysql_createdb
This function will not be available if the MySQL extension was built against a MySQL 4.x client library.
