count()当数千条记录返回1时

Question

当此文件夹中有数千条记录时,此计数为onyl返回1.

// TV Shows
$dir = 'G:/TV';
if ($handle = opendir($dir)) {

    /* This is the correct way to loop over the directory. */
    while (false !== ($file = readdir($handle))) {

        $check = mysql_query("SELECT * FROM tv_shows WHERE title = '$file'");
        $checkcount = mysql_num_rows($check);

        if ($checkcount == 0) {

            mysql_query("INSERT INTO tv_shows (id, title) VALUES ('', '$file')");

        }

    }

    echo count($dir)." Records Traversed!<br/>";

    closedir($handle);
}

表结构:id,title

文件夹结构:主文件夹中的子文件夹

 G:\TV
 G:\TV\24
 G:\TV\Family Guy

您无法count()在文件夹上使用.试试这个

// TV Shows
$dir = 'G:/TV';
$count = 0;
if ($handle = opendir($dir)) {

    /* This is the correct way to loop over the directory. */
    while (false !== ($file = readdir($handle))) {
        $count++;
        $check = mysql_query("SELECT * FROM tv_shows WHERE title = '$file'");
        $checkcount = mysql_num_rows($check);

        if ($checkcount == 0) {

            mysql_query("INSERT INTO tv_shows (id, title) VALUES ('', '$file')");

        }

    }

    echo $count." Records Traversed!<br/>";

    closedir($handle);
}

如何返回插入的新记录数？

检查一下,刚刚移动 $count++

// TV Shows
$dir = 'G:/TV';
$count = 0;
if ($handle = opendir($dir)) {

    /* This is the correct way to loop over the directory. */
    while (false !== ($file = readdir($handle))) {
        $check = mysql_query("SELECT * FROM tv_shows WHERE title = '$file'");
        $checkcount = mysql_num_rows($check);

        if ($checkcount == 0) {
            $count++;
            mysql_query("INSERT INTO tv_shows (id, title) VALUES ('', '$file')");

        }

    }

    echo $count." Records Traversed!<br/>";

    closedir($handle);
}
