如何将OCI8安装到现有的PHP？

根据 this(从PECL安装OCI8,自动化),我所要做的就是键入pecl oci8 install.

但这只会让我反复出现以下错误.

没有可用于包pecl.PHP.net/oci8的版本.

另一个网站建议我尝试使用pear install pecl / oci8.发生同样的错误.

我该怎么做才能解决这个问题？

我在Ubuntu LTS 14.04上有同样的错误：

~$sudo pecl install oci8
No releases available for package "pecl.PHP.net/oci8"
install Failed

最后的原因是代理问题：我的计算机是在公司代理服务器之后.运行以下命令以添加代理

~$sudo pear config-set http_proxy http://proxy.mycompany.com:8080/
config-set succeeded

然后再次运行该命令,它的工作方式如下

~$sudo pecl install oci8
downloading oci8-2.0.8.tgz ...
Starting to download oci8-2.0.8.tgz (190,854 bytes)

在这里,我们输入Oracle Instant客户端文件夹,如下所示：

Please provide the path to the ORACLE_HOME directory. Use 'instantclient,/path/to/instant/client/lib' if you're compiling with Oracle Instant Client [autodetect] : instantclient,/opt/oracle/instantclient_12_1

然后命令行继续输出：

祝好运.
