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();
}
?>
