As a Web programming language, PHP uses many databases to store data during the development process. Oracle is one of the most popular database systems. However, if you use PHP to connect to Oracle and the error "The computer is missing oci.dll" occurs during the connection process, then you need to find a solution.
This error occurs because PHP cannot find the OCI (Oracle Call Interface) library. The OCI library is a standard program interface provided by Oracle, which allows developers to directly call the Oracle database in PHP code. If PHP cannot find the OCI library, a "Computer is missing oci.dll" error will appear.
So, how do we solve this problem? Two solutions are given below:
Solution 1: Add the oci.dll file path to the system environment variable
Right-click Computer-> Properties-> Advanced System Settings-> Environment Variables, find PATH in the system variables, click Edit, add the oci.dll file path (such as C:\instantclient_12_1) to the end of the variable value, followed by a semicolon as separator. If you installed instantclient according to the installation steps on Oracle's official website, then the path of the environment variable is this path.
Solution 2: Copy the oci.dll file to the ext folder of PHP
Copy the oci.dll file in the Oracle instantclient installation package. dll file is copied to the $PHP_HOME/ext directory. This directory stores the files of the PHP extension module. If you are using PHP under Windows system, $PHP_HOME is usually C:\php or C:\xampp\php. You can also find it by searching extension_dir in php.ini.
Through one of the above two solutions, you can solve the problem of "the computer is missing oci.dll", and you can happily use PHP to connect to the Oracle database and perform data operations.
In short, the key to solving this problem is to find the OCI library file and tell PHP where to find it. I believe this article can help you and hope you successfully solve this problem.
