这是我的脚本：
<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
backup_tables('localhost','xxxxx','xxxxx','xxxxx');
/* 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);
}
//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";
}
$backup_file = $_SERVER['DOCUMENT_ROOT'] . '/scripts_and_crons/fr_internetlead-'.time().'.sql';
//save file
$handle = fopen($backup_file,'w+');
fwrite($handle,$return);
fclose($handle);
}
//define the receiver of the email
$to = 'email@domain.com';
//define the subject of the email
$subject = 'Test email with attachment';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate a random hash
$random_hash = md5(date('r', time()));
//define the headers we want passed. Note that they are separated with \r\n
$headers = "From: backups@domain.com\r\nReply-To: noreply@domain.com";

$attachment = chunk_split(base64_encode(file_get_contents($backup_file)));
//define the body of the message.
ob_start(); //Turn on output buffering

Hello World!!!
This is simple text email message.

<h2>Hello World!</h2>
<p>This is something with <b>HTML</b> formatting.</p>

<?php

$mail_sent = @mail($to, $subject, $message, $headers);

echo $mail_sent ? "Mail sent" : "Mail failed";
?>
我在 php 中获得的唯一调试信息是
Notice: Undefined variable: return in /var/www/vhosts/domain.com/httpdocs/scripts_and_crons/internetlead_backup.php on line 38
和
Deprecated: Function ereg_replace() is deprecated in /var/www/vhosts/domain.com/httpdocs/scripts_and_crons/internetlead_backup.php on line 50x 无穷大
我在电子邮件中收到的唯一附件是ATT00001.
echo '<pre>';
echo $return;
echo '</pre>';
打印出正确的数据。
甚至在做
echo '<pre>';
echo file_get_contents($backup_file);
echo '</pre>';
打印出正确的数据，以便写入文件，但由于某种原因，脚本无法将其附加到电子邮件中。
看不出有什么问题，有什么想法吗？

这是正确的做法。
