自己写的简单PDO sqlite类

/* 由于PDO的sqlite取出的值，老是出现首字母小写变大写的问题，只好自己写一个类来替代。

 

 

<?php

/*
0. both
1. PDORow Object
2. assoc
3. num
4. both
5. stdClass Object
6. ?  11
7. first column value

$result = sqlite_query($db, 'select bar from foo');
var_dump(sqlite_fetch_array($result));

$stmt = $pdo->prepare( 'SELECT * FROM file' );
$stmt->execute();
$rows = $stmt->fetchAll(5);
