Use tools navicat 什么的
如果要自動化導出備份sql，一般是通過命令行crontab執(zhí)行mysqldump to export

Let the tools do what the tools can do!
php code implementation:
Provide two methods for research use only.
Method 1:
Copy the code The code is as follows:

<?php
$host="localhost";
$user="root";
$password="";
$dbname="dbname";
mysql_connect($host,$user,$password);
mysql_select_db($dbname);
$mysql= "set names utf8;";
mysql_query($mysql);
$q1=mysql_query("show tables");
while($t=mysql_fetch_array($q1)){
$table=$t[0];
$q2=mysql_query("show create table $table");$table");
$sql=mysql_fetch_array($q2);
$mysql.=$sql['Create Table'].";n";
$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 $table$sql=mysql_fetch_array($q2);
$mysql.=$sql[' Create Table'].";n";
$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 .="n";
}
$filename=$dbname.date('Ymj').".sql";
$fp = fopen($filename,'w');
fputs($fp,$mysql) ;
fclose($fp);echo "Data backup successful, backup file generated".$filename;?>
Second method:
Copy the code The code is as follows:

<?php
$host="localhost";

$password="";
$dbname="dbname";
backup_tables($host,$user,$password,$dbname );
/
backup the db OR just a table
/
function backup_tables($host,$user,$pass,$name,$tables = '*')
{

$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);

//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);
}
$return = '';
//cycle through
foreach($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));
$return.= "nn".$row2[1]. ";nn";

for ($i = 0; $i < $num_fields; $i++)
{
while($row = mysql_fetch_row($result))
{
$return.= 'INSERT INTO '.$table.' VALUES( ';

{
$row[$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.= ','; }
}

public function uploadAction(){
        $root = $this->config->database->username;
        $pass = $this->config->database->password;
        $dbname = $this->config->database->dbname;
        $timestr = date('YmdHis');
        $fileName = "backupMysqlFile-$timestr.sql.gz";
        $filePath = "/backup/mysql/$fileName";
        $command = "mysqldump -h127.0.0.1 -u$root -p$pass $dbname | gzip > $filePath";
        exec($command);
        $ret = $this->qiniuuploadMgr->putFile($this->qiniuToken,$fileName,$filePath);
    }

> #crontab -e

backupmysql.sh里面只有一個請求CURL請求php action
