在我的情况下,数据库几乎超过2GB,因此占用太多时间,因此如何分解它的任何想法,请帮助`backup_tables('localhost','xyz','xyz','xyz'); >
功能backup_tables($ host,$ user,$ pass,$ name) { $ link = mysqli_connect($ host,$ user,$ pass,$ name);
if($tables == '*')
{
$tables = array();
$result = mysqli_query($link, 'SHOW TABLES');
while($row = mysqli_fetch_row($result)){
$tables[] = $row[0];}
}
else{ $tables = is_array($tables) ? $tables : explode(',',$tables);}
//cycle through
foreach($tables as $table)
{
$result = mysqli_query($link, 'SELECT * FROM '.$table);
$num_fields = mysqli_num_fields($result);
$return.= 'DROP TABLE '.$table.';';
$row2 = mysqli_fetch_row(mysqli_query($link,'SHOW CREATE TABLE '.$table));
$return.= "\n\n".$row2[1].";\n\n";
for ($i = 0; $i < $num_fields; $i++)
{
while($row = mysqli_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
$path = 'downloads/';
$handle = fopen($path.'db-backup-'.(md5(implode(',',$tables))).'.sql','w+');
$filewrite = fwrite($handle,$return);
$fileList = glob('downloads/*.sql');
echo $filename = basename($fileList['0']);
fclose($handle);`

只需转到phpmyadmin并执行转储,这是最佳解决方案。
