小文件php+SQLite存储方案
我们草根站长购买的虚拟主机往往都有文件数量限制，大量小文件占用大量资源，落伍精华区也有兄弟推荐豆瓣的解决方法，但是要有主机权限。只能另装思路，采用php+SQLite解决问题，经过我测试，切实可行，现在推荐给大家。
现在公开代码：
创建数据库文件：php1.php
$db = new SQLite3('mysqlitedb.db');
//获取文件2进制流
$filename = "//www.jb51.net/logo.gif";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize ($filename));
fclose($handle);
//创建数据表
$db->exec('CREATE TABLE person (idnum TEXT,name TEXT,photo BLOB)');
$stmt = $db->prepare("INSERT INTO person VALUES ('41042119720101001X', '张三',?)");
$stmt->bindValue(1, $contents, SQLITE3_BLOB);
$stmt->execute();
读数据文件：php2.php
<?php
$pdo = new SQLite3('mysqlitedb.db');
$results = $pdo->query('select * from person');
while ($row = $results->fetchArray()) {
ob_start();
header("Content-Type: image/jpg");
echo $row['photo'] ;
ob_end_flush();
}
?>
