php鏈接oracle oracle開啓擴展

<?php

/**

* 因爲公司的須要，使用php+oracle開發項目，oracle由於有專門人員開發設計，咱們只需遠程調用

*因而乎遇到了蛋疼的問題就是開啓oracle擴展的問題，雖然你在php.ini文件中打開了extension=php_oci8.dll

*單身在phpinfo中仍然看不到oracle擴展，這樣oracle的操做方法就不能用，

*因而就要去oracle官方網上下載一個文件包 instantclient-basic-nt-11.2.0.3.0.zip，

*解壓到任意地方，而後將D:\instantclient這個地址配置到環境變量裏面這樣*oracle的擴展就會開啓，天然方法均可以使用了，就像用mysql同樣了

*固然數據庫鏈接類仍是須要的因而我就寫了一個php鏈接oracle的類以下
