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 = "https://3water.com/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(); } ?>
