我一直在做遞歸目錄掃描掃描文件夾,並將它們添加到我的mysql數據庫,如果它不在那裏。我唯一的問題是,無論我如何編寫表單的Check部分,它仍然跳過一些記錄和/或它檢測到它已經在那裏,當有一些相同的名稱以0結尾時。 +以下代碼。MySQL結果檢查關閉...什麼是最佳方法?
表:
CREATE TABLE IF NOT EXISTS `comics` (
`id` int(255) NOT NULL AUTO_INCREMENT,
`publisher` varchar(255) NOT NULL,
`arc` varchar(255) NOT NULL,
`issue` int(5) NOT NULL,
`title` varchar(255) NOT NULL,
`plot` longtext NOT NULL,
`price` varchar(20) NOT NULL DEFAULT '0',
`files` int(255) NOT NULL,
`size` varchar(255) NOT NULL,
`cover` text NOT NULL,
`month` int(2) unsigned zerofill NOT NULL,
`day` int(2) unsigned zerofill NOT NULL,
`year` int(4) unsigned zerofill NOT NULL,
`added` date NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `arc` (`arc`,`issue`,`title`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
記錄:
INSERT INTO `comics` (`id`, `publisher`, `arc`) VALUES
(10463, '', 'Green Wake 10');
INSERT INTO `comics` (`id`, `publisher`, `arc`) VALUES
(10462, '', 'Green Wake 1');
如果第一插入件是第二插入之前存在,則第二個回來爲已經是在數據庫中。
代碼,它位於現在:
<?php
$base = "D:/comics/";
if (isset($_REQUEST['sub'])) {
$sub = $_REQUEST['sub'];
echo "<h2>Scanning Comics Starting With ".$sub."</h2>";
if ($handle = opendir('D:/comics/'.$sub.'/')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != '$RECYCLE.BIN' && $entry != 'System Volume Information' && $entry != '.' && $entry != '..') {
$entry1 = $entry;
$entry = str_replace(" - ", ": ", $entry);
$exists = mysql_query('SELECT * FROM comics WHERE arc LIKE "'.$entry.'%"');
$exists1 = mysql_num_rows($exists);
if ($exists1 == 0) {
$directory = $base.$sub."/".$entry1;
$filecount = count(glob($directory."/"."*.*"));
$size2 = 0;
$d = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($directory),
RecursiveIteratorIterator::SELF_FIRST
);
foreach($d as $file){
$size2 += $file->getSize();
}
$size = $size2/1024;
$modified = date("Y-m-d", filemtime($directory));
mysql_query('INSERT INTO comics (arc, files, size, added) VALUES ("'.$entry.'", "'.$filecount.'", "'.$size.'", "'.$modified.'")');
print "<li>Inserted <b>".$entry."</b> With A File Count Of <b>".$filecount."</b> & A Total Size Of <b>".$size."</b> MB Last Modified On <b>".$modified."</b>.</li>";
}
}
}
}
}
?>
不同的支票查詢我想:
$exists = mysql_query('SELECT * FROM comics WHERE arc LIKE "'.$entry.'%"');
// Returns As Already Being In The Database.
$exists = mysql_query('SELECT * FROM comics WHERE arc = "'.$entry.'"');
// Returns The Successfully Imported Message (but doesn't execute the insert query) For All Folders Found. Even If It Is There Or Not.
這將是一個更精確的檢查方法?
是的,我認爲這就是爲什麼我試圖匹配它'arc ='$ entry''但是也不能正確返回。 – rackemup420 2012-04-01 15:15:19
究竟是什麼返回'$ exists = mysql_query('SELECT * FROM comics WHERE arc =''。$ entry。'「');'和'exists1 = mysql_num_rows($ exists); 'set exists1 = 0? – grifos 2012-04-01 15:28:36
此外,我還建議您在附加到您的查詢的文本上使用'mysql_real_escape_string',以避免任何錯誤(減少sqli漏洞,仍然容易發生評論char)。然而,對於給定的測試值,它不應該改變任何東西。 – grifos 2012-04-01 15:30:50
