php连接oracle oracle开启扩展

<?php

/**

* 由于公司的需要，使用php+oracle开发项目，oracle因为有专门人员开发设计，我们只需远程调用

*于是乎遇到了蛋疼的问题就是开启oracle扩展的问题，虽然你在php.ini文件中打开了extension=php_oci8.dll

*单身在phpinfo中仍然看不到oracle扩展，这样oracle的操作方法就不能用，

*于是就要去oracle官方网上下载一个文件包 instantclient-basic-nt-11.2.0.3.0.zip，

*解压到任意地方，然后将D:\instantclient这个地址配置到环境变量里面这样*oracle的扩展就会开启，自然方法都可以使用了，就像用mysql一样了

*当然数据库连接类还是需要的于是我就写了一个php连接oracle的类如下
