This article will introduce you to a PHP backup MySQL database instance using XML. Personally, I think this method is only suitable for users with small data volumes and low security requirements.

The following is the file code for backing up the Mysql database through Apache+PHP under Linux:
File 1, Listtable.php (file lists all tables in the database for backup)
Please select the table to backup:

"; //List all tables

The code is as follows

代码如下	复制代码
$con=mysql_connect('localhost','root','xswlily'); $lists=mysql_list_tables("embed",$con); //数据库连接代码 $i=0; while($i$tb_name=mysql_tablename($lists,$i); echo "".$tb_name." "; //列出所有的表格 $i++;} ?>

Copy code

$con=mysql_connect('localhost',' root','xswlily'); $lists=mysql_list_tables("embed",$con);

代码如下

复制代码

"") header("Location:listtable.php");?>

$con=mysql_connect('localhost','root','xswlily');
$query="select * from $table ";
//数据库查询
$result=mysql_db_query("embed",$query,$con);
$filestr="<"."?xml version="1.0" encoding="GB2312"?".">";
$filestr.="<".$table."s>";
while ($row=mysql_fetch_array($result))
//列出所有的记录
{$filestr.="<".$table.">";
$fields=mysql_list_fields("embed",$table,$con);
$j=0;
//$num_fields=mysql_field_name($fields,$j);
//echo $num_fields;
while ($j$num_fields=mysql_field_name($fields,$j);
$filestr.="<".$num_fields.">";
$filestr.=$row[$j];
$filestr.="";
$j++;}
$filestr.="";
}
$filestr.="";
echo $filestr;
//以下是文件操作代码
$filename=$table.".xml";
$fp=fopen("$filename","w");
fwrite($fp,$filestr);
fclose($fp);
Echo "数据表".$table."已经备份成功！";?>

//Database connection code

$i=0;
while($i$tb_name=mysql_tablename($lists,$i);

echo "".$tb_name."

$i++;} ?>
