The following is the file code for backing up the Mysql database through Apache+PHP under Linux:
File 1, Listtable.php (the file lists all tables in the database for backup selection)
Please select the tables to be backed up:
$con=mysql_connect('localhost','root','xswlily');
$lists=mysql_list_tables("embed ",$con);
//Database connection code
$i=0;
while($i$tb_name=mysql_tablename($lists,$i);
echo "".$tb_name ."
";
//List all tables
$i++;}
?>
File 2, Backup.php
$con=mysql_connect('localhost','root ','xswlily');
$query="select * from $table ";
//Database query
$result=mysql_db_query("embed",$query,$con);
$filestr="<"."?xml version="1.0" encoding="GB2312"?".">";
$filestr.="<".$table."s>";
while ($row=mysql_fetch_array($result))
//List all records
{$filestr.="<".$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;
//The following is the file operation code
$filename=$table.".xml";
$fp=fopen("$filename","w");
fwrite($fp,$filestr );
fclose($fp);
Echo "Data table".$table." has been backed up successfully! ";?>
By operating the above files, you can back up the selected tables in the database.
The above mainly introduces the operation of XML backup database through PHP The method is actually not complicated. Through XML, we can back up various databases. Of course, we can also restore the backed-up XML documents to the database through related methods, which will not be described in detail here
