注明:
php默认状态下是不能与oracle数据库连接的，我们得 在php.ini的Windows Extensions段修改成
extension_dir = "所要加载的dll的文件路径" （如c:phpextensions）
extension=php_oci8.dll
extension=php_oracle.dll
第二步：
iis中设置isapi

说明函数功能:
integer ora_logon(string user , string password)根据指定用户连接oracle数据库服务器
integer ora_open(integer connection)给出的连接上执行查询。PHP生成一个指示器，解析查询
integer ora_do(integer connection, string query)为查询并准备好执行
integer ora_parse(integer cursor, string query)ora_parse函数解析过的查询。
