Taking mysql data backup with php5
I am using php5 and mysql5.- in my local server
I want to take mysql database backup ( in my local server ) - just by copying the datafile ( located in mysql server in the folder data )
I have copied a particular table name account.frm file - but it is not working It is showing the table name but it is showing error that ( I checked in the mysql query bro开发者_如何转开发wser ) that cannot fetch the table details.
I have used mysqldump it is also not working.
Please help me to take backup and work correctly.
I use PHP to create compressed MySQL dumps daily. If using PHP under Linux, a generic representation of what you need is:
exec('mysqldump -u [username] --password=[password] [databaseName] > [sqlDumpFilename] ');
exec('tar cvzf [compressedFilename] [sqlDumpFilename]');
This will result in [compressedFilename] containing a compressed MySQL dump to use as you need. Skip the compression step if not needed.
Did you tried backuping your database with phpmyadmin http://www.phpmyadmin.net/home_page/index.php ?
you should have phpmyadmin installed, - if you installed localserver bundle, but if not take a look at this php function for backuping database :
function backup_tables($tables = '*')
{
// the $db var is connection to your database!
global $db;
//get all of the tables
if($tables == '*')
{
$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(',',$tables);
}
//cycle through
foreach($tables as $table)
{
$result = mysql_query('SELECT * FROM '.$table);
$num_fields = mysql_num_fields($result);
$return.= 'DROP TABLE '.$table.';';
$row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
$return.= "\n\n".$row2[1].";\n\n";
for ($i = 0; $i < $num_fields; $i++)
{
while($row = mysql_fetch_row($result))
{
$return.= 'INSERT INTO '.$table.' VALUES(';
for($j=0; $j<$num_fields; $j++)
{
$row[$j] = addslashes($row[$j]);
$row[$j] = ereg_replace("\n","\\n",$row[$j]);
if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
if ($j<($num_fields-1)) { $return.= ','; }
}
$return.= ");\n";
}
}
$return.="\n\n\n";
}
//save file
// specifiy the path where you want to backup the file...
$filess = 'db-backup-'.time().'-'.(md5(implode(',',$tables))).'.sql';
$handle = fopen($filess,'w+');
fwrite($handle,$return);
fclose($handle);
return $filess;
}
the function will create INSERT INTO instructions in .sql file, which then can be used for import into newly created database.
