Are there any compatibility issues when installing PHP with specific versions of databases like MySQL or PostgreSQL?

Hey everyone,
I have been working on developing a website using PHP and I'm now at the stage of configuring the database. I'm currently trying to decide between MySQL and PostgreSQL as the database for my project. However, before I make my choice, I want to make sure that PHP is compatible with both databases.

Can anyone shed some light on the compatibility issues that might arise when installing PHP with specific versions of databases like MySQL or PostgreSQL? Are there any specific versions of PHP, MySQL, or PostgreSQL that work well together and others that should be avoided?

I appreciate any insights or experiences you can share. Thank you in advance!

Hey there,

I have personally worked with PHP and both MySQL and PostgreSQL, so I can share my experience regarding compatibility.

I've found that PHP has good compatibility with both MySQL and PostgreSQL. However, it's crucial to ensure that you have the appropriate database extensions enabled in your PHP installation for seamless connectivity.

For MySQL, you can use the mysqli or PDO extension. These extensions have been widely used and are compatible with various versions of MySQL. I have successfully used both extensions with PHP 5.6 and newer versions, as well as different versions of MySQL, including 5.7 and 8.0.

As for PostgreSQL, the recommended extensions are PDO_PGSQL and pgsql. Personally, I've used PDO_PGSQL extensively with PHP 7.2 and PostgreSQL 10 and 11, and they worked harmoniously without any compatibility issues.

In my experience, it's essential to keep your PHP, MySQL, and PostgreSQL versions updated to ensure the best compatibility and stability. Remember to check the documentation for each version to ensure full support.

I hope this information helps you make an informed decision. If anyone has additional insights or experiences to share, I would love to hear them.




I'd like to share my personal experience with PHP and the compatibility aspects with MySQL and PostgreSQL.

In my case, I have primarily used PHP with MySQL for my projects, and I haven't encountered any significant compatibility issues. The mysqli extension has been my go-to choice for connecting PHP with MySQL, and it has worked smoothly across PHP versions 5.6 to 7.4. As for MySQL, I have worked with versions 5.5 and 8.0, and they both integrated seamlessly with PHP.

While I haven't extensively used PostgreSQL with PHP, I have had the chance to experiment with it on a smaller project. Using the PDO_PGSQL extension, I connected PHP 7.3 with PostgreSQL 10, and the setup worked well without any glaring compatibility issues.

Based on my experience, it appears that PHP has good compatibility with both MySQL and PostgreSQL databases. However, it's always a good idea to review the documentation and release notes for any specific version requirements or known compatibility issues that may exist.

Remember, your personal preference and the specific requirements of your project should guide your choice between MySQL and PostgreSQL. Both databases have their strengths, so understanding your project's needs will help you make an informed decision.

If anyone has additional experiences or insights to contribute, feel free to add to the discussion.

Best regards,



I wanted to chime in with my personal experience working with PHP and different database options.

I have primarily used PHP with MySQL for my projects, and it has been a solid combination for me. I found that PHP's mysqli extension seamlessly integrates with MySQL, allowing me to perform database operations efficiently. I have worked with PHP versions ranging from 5.4 to 7.4, and they all worked well with MySQL versions 5.6 and 5.7.

However, during one of my recent projects, I decided to give PostgreSQL a try, and I must say, I was pleasantly surprised. The PDO_PGSQL extension provided excellent support for connecting PHP with PostgreSQL. I used PHP 7.3 and PostgreSQL 11, and everything worked flawlessly. It's worth mentioning that I faced no major compatibility issues during this particular setup.

In my opinion, both MySQL and PostgreSQL can work well with PHP, as long as you ensure that the appropriate extensions are enabled and the versions are compatible. However, I would recommend carefully reviewing the documentation and release notes for any known compatibility issues specific to the versions you plan to use.

I hope my experience provides another perspective for you to consider. If anyone has further insights or recommendations, feel free to share!
