我正在构建一个脚本，将数据从上传的 XML 文件导入 MySQL，但不是直接导入。该函数本身只有一个查询，但它总是超时。该查询必须连接两个表才能找到一个 ID，该 ID 将与 XML 数据一起插入到第三个表中。
这是执行此操作的函数：
public function imprtTVLApi($file) {
global $db, $user;
$ext = pathinfo($file, PATHINFO_EXTENSION);
$message = '';
$text = '';
$streaming_websites = array(
'megavideo.com' => '1',
'vidxden' => '2',
'videobb.com' => '4',
'veevr.com' => '5',
'vureel.com' => '6',
'2gb-hosting.com' => '7',

);
if ( $ext == "xml") :
$tv = new DomDocument();
$tv->recover = TRUE;
$tv->load($file) or die("Could not load the file! " .$file);
$tvSearch = $tv->getElementsByTagName( "url" );
$count = 0;
foreach( $tvSearch as $tv ) {
// name
$names = $tv->getElementsByTagName('name');
$name = $names->item(0)->nodeValue;
// seasons
$seasons = $tv->getElementsByTagName('season');
$season = $seasons->item(0)->nodeValue;
// episode
$episodes = $tv->getElementsByTagName('episode');
$episode = $episodes->item(0)->nodeValue;
// episode
$links = $tv->getElementsByTagName('loc');
$link = $links->item(0)->nodeValue;
$user = $user->uid;
$url = $db->escape($link);
$stream1 = $this->getHostFromURL($url);
$stream = $streaming_websites[$stream1];
$added = time();
$status = "ok";
$sql = 'SELECT e.id AS epid FROM ' .$this->epTable. ' AS e INNER JOIN ' .$this->tvTable. ' AS t ON e.show_ID = t.id WHERE t.title = "' .$name. '" AND e.season = "' .$season. '" AND e.episode = "' .$episode. '" LIMIT 1';
$row = $db->first($sql);
if( isset($row['epid'])) {
$data = array(
'user_ID' => $user,
'url' => sanitize($url),
'stream_ID' => $stream,
'e_ID' => intval($row['epid']),
'added' => intval($added),
'status' => $status
);
$text .= "INSERT IGNORE INTO " .$this->lkTable. " (`user_ID`, `url`, `stream_ID`, `e_ID`, `added`, `status`) VALUES ('" .$data['user_ID']. "', '" .$data['url']. "', '" .$data['stream_ID']. "', '" .$data['e_ID']. "', '" .$data['added']. "', '" .$data['status']. "')";
} else {
$message = "Show not found";
}
$count++;
}
$myFile = "export_" .$user->uid. "_" .time(). ".sql";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $text;
fwrite($fh, $stringData);
fclose($fh);
parse_mysql_dump($myFile);
unlink($myFile);
$message = "Links: " .$count. ", Your links were added and they will show up on the site in a minute!";
else :
$message = "Incorrect file format! Must be XML!";
endif;
print($message);
}
这是数据库结构：

循环创建 .sql 文件后，数据将发送到 MySQL。这里的关键是找到将在链接表中导入的剧集 ID。
您对如何使其更快或有任何想法有什么建议吗？
