php读取sqlite数据库入门实例

php读取sqlite数据库的例子，php编程中操作sqlite入门实例.
原文参考：http://www.jbxue.com/article/php/22383.html
在使用SQLite前，要确保php.ini中已经启用sqlite和pdo配置

打开PHP.INI文件，打下以下扩展：
extension=php_pdo.dll

extension=php_pdo_sqlite.dll
extension=php_sqlite.dll
sqlite_open命令是打开一个数据库文件。
如果没有文件则创建。

sqlite_query可以执行SQL语句。
创建一个表并插入数据。

sqlite_unbuffered_query发出SELECT语句。
循环并显示结果。

unable to open a temporary database file for storing temporary tables
无法打开存储临时表的临时数据库文件,在Windows环境中，如果出现上述错误，
请使用putenv("TMP=C:/temp");指定临时文件夹。

具体请看代码：

<?<span>php
</span><span>//</span><span>临时目录 在Windows环境中，如果出现上述错误，请使用putenv("TMP=C:/temp");指定临时文件夹。
//putenv("TMP=C:/temp");

//打开数据库 www.jbxue.com</span>
