mysql 页面正常 数据库文件sql乱码

如果你的库原来是gbk编码，则把以下代码存为php文件，记得把下面的数据库名跟数据库帐号密码填上

define('DB_NAME', 'putyourdbnamehere');    // 数据库名
define('DB_USER', 'usernamehere');     // MySQL用户名
define('DB_PASSWORD', 'yourpasswordhere'); // 密码
define('DB_HOST', 'localhost');    // 很大可能你无需修改此项

 // Since we cannot use the WordPress Database Abstraction Class (wp-db.php),
 // we have to make an a stand-alone/direct connection to the database.
 $link_id = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die('Error establishing a database connection');
 mysql_select_db(DB_NAME, $link_id);

随便放到一个可以访问到库的php站点下运行即可。

如果你的库是utf-8编码，则运行以下代码，，记得把下面的数据库名跟数据库帐号密码填上

define('DB_NAME', 'putyourdbnamehere');    // 数据库名
define('DB_USER', 'usernamehere');     // MySQL用户名
define('DB_PASSWORD', 'yourpasswordhere'); // 密码
define('DB_HOST', 'localhost');    // 很大可能你无需修改此项

function UTF8_DB_Converter_DoIt() {
$tables = array();
$tables_with_fields = array();

// Since we cannot use the WordPress Database Abstraction Class (wp-db.php),
// we have to make an a stand-alone/direct connection to the database.
$link_id = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die('Error establishing a database connection');
mysql_select_db(DB_NAME, $link_id);

// Gathering information about tables and all the text/string fields that can be affected
// during the conversion to UTF-8.
$resource = mysql_query("SHOW TABLES", $link_id);
while ( $result = mysql_fetch_row($resource) )
$tables[] = $result[0];

if ( !empty($tables) ) {
foreach ( (array) $tables as $table ) {
$resource = mysql_query("EXPLAIN $table", $link_id);
while ( $result = mysql_fetch_assoc($resource) ) {
if ( preg_match('/(char)|(text)|(enum)|(set)/', $result['Type']) )
$tables_with_fields[$table][$result['Field']] = $result['Type'] . " " . ( "YES" == $result['Null'] ? "" : "NOT " ) . "NULL " .  ( !is_null($result['Default']) ? "DEFAULT '". $result['Default'] ."'" : "" );
}
}

// Change all text/string fields of the tables to their corresponding binary text/string representations.
foreach ( (array) $tables as $table )
mysql_query("ALTER TABLE $table CONVERT TO CHARACTER SET binary", $link_id);

// Change database and tables to UTF-8 Character set.
mysql_query("ALTER DATABASE " . DB_NAME . " CHARACTER SET utf8", $link_id);
foreach ( (array) $tables as $table )
mysql_query("ALTER TABLE $table CONVERT TO CHARACTER SET utf8", $link_id);

// Return all binary text/string fields previously changed to their original representations.
foreach ( (array) $tables_with_fields as $table => $fields ) {
foreach ( (array) $fields as $field_type => $field_options ) {
mysql_query("ALTER TABLE $table MODIFY $field_type $field_options", $link_id);
}
}

// Optimize tables and finally close the mysql link.
foreach ( (array) $tables as $table )
mysql_query("OPTIMIZE TABLE $table", $link_id);
mysql_close($link_id);
} else {
die('There are no tables?');
}

return true;
}
UTF8_DB_Converter_DoIt();
?>

运行完之后登录phpmyadmin，查询下就知道乱码已经恢复！
