我想备份我的数据库并使用 php 将其邮寄到我的电子邮件 ID。我找到了一个脚本，它备份了我的数据库并以 zip 形式将其邮寄给我，但是当我尝试执行该脚本时，它运行良好，但邮件没有进入我的收件箱。这是脚本：

<?php
$db_host="localhost";   //mysql host  
$db_user="*******";  //databse user name
$db_pass="*******";  //database password
$db_name="******";  //database name
$tables="*";   // use * for all tables or use , to seperate table names
$email="*******";     //your email id
///////////////////////////////////////////////////////////////////////////////////////////

/////////don't need to change bellow //////

backup($db_host,$db_user,$db_pass,$db_name,$tables,$email);
function backup($db_host,$db_user,$db_pass,$db_name,$tables = '*',$email)
{

  $con= mysql_connect($db_host,$db_user,$db_pass);
  mysql_select_db($db_name,$con);

  //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
  $filename='db-backup-'.time().'-'.(md5(implode(',',$tables))).'.sql';
  $handle = fopen($filename,'w+');
  fwrite($handle,$return);
  fclose($handle);
  compress($filename);
  send_mail($filename.".zip",$email);
}

function send_mail($filepath,$email)
{

$from = "Backup <cepheisys.com/mac>";
$subject = "Database backup";
$message="This attachment contains the backup of your database.";
$separator = md5(time());

// carriage return type (we use a PHP end of line constant)
$eol = PHP_EOL;

// attachment name
$filename = "backup.zip";

//$pdfdoc is PDF generated by FPDF
$attachment = chunk_split(base64_encode(file_get_contents($filepath)));

// main header
$headers  = "From: ".$from.$eol;
$headers .= "MIME-Version: 1.0".$eol; 
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"";

// no more headers after this, we start the body! //

$body = "--".$separator.$eol;
$body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
$body .= "This is a MIME encoded message.".$eol;

// message
$body .= "--".$separator.$eol;
$body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
$body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$body .= $message.$eol;

// attachment

$body .= "Content-Transfer-Encoding: base64".$eol;
$body .= "Content-Disposition: attachment".$eol.$eol;
$body .= $attachment.$eol;
$body .= "--".$separator."--";

// send message
if (mail($email, $subject, $body, $headers)) {
    echo "Your backup sent to your email id";
    header("refresh: 1; main.php");
} else {
    echo "Oops mail can not be send";
}
}
function compress($filepath)

     {

         $zip = new ZipArchive();
  $file=$filepath.".zip";
 if($zip->open($file,1?ZIPARCHIVE::OVERWRITE:ZIPARCHIVE::CREATE)===TRUE)
 {
   // Add the files to the .zip file
   $zip->addFile($filepath);

   // Closing the zip file
   $zip->close();
 }
     }

我这样做是出于一种爱好，因此任何输入都将受到谦虚的赞赏。

  1. $row[$j] = ereg_replace("\n","\\n",$row[$j]); 已折旧，应更换为：

    $pattern = '/\\\n/';
$replacement = '\\\\\n';
$row[$j] = preg_replace($pattern, $replacement, $row[$j] );

  2. 我无法让您的代码有效地通过电子邮件发送，所以我只是通过电子邮件将链接发送给自己。我必须点击链接并通过 ftp 登录，但它就在那里。LMK 如果您有任何意见。

  3. 我在您的代码中返回了路径，然后将文件位置添加到我的数据库中::

    function Add_BU_to_Database ($filename){
    $conn = db_connect(); //connects to my db
    $BU_Hist_num = General_Get_num('BU_History','BU_Hist_num'); //gets primary field
    $now = time(); 
    $BU_Add_Qry = $conn->query("insert into BU_History 
    (BU_Hist_num,BU_Path,BU_Time_Add,BU_Time_Del,BU_Status)                 
    Values('".$BU_Hist_num."','".$filename."','".$now."','','Active')");
}//end function`

  4. 然后我更新了页面顶部的ini，这样它就不会超时::

    ini_set('memory_limit', '1G'); 
ini_set('max_execution_time', 300);

  5. 然后我编写了其余的代码来删除旧文件并在新的 php 文件上更新数据库::

    <?php
ini_set('memory_limit', '1G'); 
ini_set('max_execution_time', 300);

$conn = db_connect();
$AweekAgo = time()-1209600;

$DBDeletionQry = $conn->query("select * from BU_History where BU_Status = 'Active' and BU_Time_Add < '$AweekAgo' ");
$DBD_rows = mysqli_num_rows($DBDeletionQry);

echo "Files older than two weeks: ".$DBD_rows."<br>";
$filesdeleted = 0;

for($i=0;$i<$DBD_rows;$i++){
    //Finds each file path
    $DBD_row = mysqli_fetch_assoc($DBDeletionQry);
    $BU_Path = "".$DBD_row['BU_Path'];
    $BU_Hist_num = $DBD_row['BU_Hist_num'];
    //Shows Paths
    echo $BU_Path."<br>";

    //Delete's File
    if(unlink($BU_Path)){$filesdeleted = $filesdeleted+1;}

    //Updates the Database
    $now = time();
    $DBDUpdate = $conn->query("update BU_History set BU_Time_Del = '$now',     BU_Status = 'Inactive' where BU_Hist_num = '$BU_Hist_num' ");

}//end for
echo "Files deleted: ".$filesdeleted."<br>";
?>

  6. 最后但并非最不重要的一点是，我使用我的 cron 管理器来运行备份和删除备份 .php 文件。
