 php数据库备份脚本

  代码如下:

  

  // 备份数据库

  $host = "localhost";

  $user = "root"; //数据库账号

  $password = ""; //数据库密码

  $dbname = "mysql"; //数据库名称

  // 这里的账号、密码、名称都是从页面传过来的

  if (!mysql_connect($host, $user, $password)) // 连接mysql数据库

  {

  echo '数据库连接失败,请核对后再试';

  exit;

  }

  if (!mysql_select_db($dbname)) // 是否存在该数据库

  {

  echo '不存在数据库:' . $dbname . ',请核对后再试';

  exit;

  }

  mysql_query("set names 'utf8'");

  $mysql = "set charset utf8; ";

  $q1 = mysql_query("show tables");

  while ($t = mysql_fetch_array($q1))

  {

  $table = $t[0];

  $q2 = mysql_query("show create table `$table`");

  $sql = mysql_fetch_array($q2);

  $mysql .= $sql['Create Table'] . "; ";

  $q3 = mysql_query("select * from `$table`");

  while ($data = mysql_fetch_assoc($q3))

  {

  $keys = array_keys($data);

  $keys = array_map('addslashes', $keys);

  $keys = join('`,`', $keys);

  $keys = "`" . $keys . "`";

  $vals = array_values($data);

  $vals = array_map('addslashes', $vals);

  $vals = join("','", $vals);

  $vals = "'" . $vals . "'";

  $mysql .= "insert into `$table`($keys) values($vals); ";

  }

  }

  $filename = $dbname . date('Ymjgi') . ".sql"; //存放路径,默认存放到项目最外层

  $fp = fopen($filename, 'w');

  fputs($fp, $mysql);

  fclose($fp);

  echo "数据备份成功";

  ?>
