mysql_create_db — Create a MySQL database
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
說明
$database_name
[, resource $link_identifier = NULL
] )mysql_create_db() attempts to create a new database on the server associated with the specified link identifier.
參數
-
database_name -
The name of the database being created.
-
link_identifier -
MySQL 的連接識別符。如果沒有指定，預設使用最後被 mysql_connect() 打開的連接。如果沒有找到該連接，函式會嘗試呼叫 mysql_connect() 建立連接並使用它。如果發生意外，沒有找到連接或無法建立連接，系統發出
E_WARNING級別的警告信息。
回傳值
如果成功則回傳 TRUE，失敗則回傳 FALSE。
範例
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";
}
?>
上例的輸出類似於：
Database my_db created successfully
註釋
Note:
為了保證向前相容，可以使用下面的別名，但不贊成使用它： mysql_createdb()
Note:
This function will not be available if the MySQL extension was built against a MySQL 4.x client library.
