He，
几天后，我尝试在新服务器上的PHP7上安装PDO_OCI。我曾经在其他服务器PDO_OCI上，但在PHP 5.4上，一切都很好，这个版本没有问题。
我收到消息：

我的配置：Linux服务器系统Linux 3.16.0-4-amd64#1 SMP Debian 3.16.7-ckt20-1+deb8u4（2016-02-29）x86_64PHP PHP版本7.0.4-1~dotdeb+8.1PDO驱动程序mysqlOCI8支持已启用（正在工作）。
我已经阅读了PHP7中包含的PDO_OCIhttps://github.com/php/php-src/tree/PHP-7.0.7/ext/pdo_oci但是如何激活它呢？
我的PHP 5.4代码在此服务器PHP7上不起作用。
有人有解决方案吗？

下载PHP的源文件（从https://www.php.net/downloads，例如。https://www.php.net/distributions/php-7.4.16.tar.bz2)：
PHP_VERSION=7.3.27 # Set to your PHP version
cd /tmp
sudo apt-get install php-dev -y
wget https://www.php.net/distributions/php-${PHP_VERSION}.tar.gz
tar xvfj php-${PHP_VERSION}.tar.bz2
rm php-${PHP_VERSION}.tar.bz2
将pdo_oci复制到/tmp:
cp -r /tmp/php-${PHP_VERSION}/ext/pdo_oci /tmp
cd /tmp/pdo_oci
构建插件：
sudo phpize
sudo ./configure --enable-option-checking=fatal # Optionally add more parameters
sudo make
sudo make install
Finall，创建和链接文件：
sudo echo "extension=pdo_oci.so" > /etc/php/7.3/mods-available/pdo_oci.ini
sudo ln -s /etc/php/7.3/mods-available/pdo_oci.ini /etc/php/7.3/apache2/conf.d/20-pdo_oci.ini
重新启动apache2
此扩展已被放弃，不会编译。为什么？PHP的API在版本7中发生了重大变化；您看到的错误表明内部函数签名已经更改：
/home/pear/download/PDO_OCI-1.0/oci_driver.c: In function 'pdo_oci_fetch_error_func':
/home/pear/download/PDO_OCI-1.0/oci_driver.c:51:3: error:
too many arguments to function 'add_next_index_string' add_next_index_string(info, einfo->errmsg, 1);
如何修复这个问题取决于你如何安装PHP。我希望你自己编译它，因为你对扩展也是这样做的。如果是这样，只需使用--with-pdo-oci=DIR重新编译即可，其中DIR是Oracle主目录。
如果您是通过apt从软件包安装的，那么您有几个选择。1） 看看你是否可以用同样的方式获得PDO-OCI驱动程序（看起来没有。）2）删除你的包，从源代码开始做所有事情。3） 请尝试第三方驱动程序。
