If you plan to deploy a Drupal site to OCI using MySQL Database Service, there is a very easy way to perform that deployment: using OCI’s Resource Manager !

As you know, security is something very important for Oracle in OCI, therefor, exposing the database on the Internet is not allowed.

Even if you are not using OCI, I really recommend you to follow that principle and never expose your database to Internet !

I already cover this in many previous posts. But I also understand that for people not being a sysadmin, this can be complicated the first time.

That’s why, all this can be automated using a stack to deploy in Resource Manager.

The first thing to do when you have your OCI account, it’s to download the stack from GitHub: https://github.com/lefred/oci-drupal-mds

Then in OCI’s dashboard, just …

Having spent the majority of this year programming a custom reporting dashboard for my employer written in PHP and MySQL, it is an understatement to say that I have learned a lot. Nothing beats real-world experience and I really have come into my own with PHP, learning more and more daily as I continue progressing forward on my goal of becoming a Back-End Web Developer. I have written several PHP-related posts this year and wanted to provide them all in one easy-to-access list. Enjoy!

I recently received several messages from developers not being comfortable with command line when they need to create schemas, tables, … They were asking me for an easy alternative when testing MDS.

There is a very popular tool in the developer community to manage their databases in MySQL: PHPMyAdmin.

So if you are trying MDS (MySQL Database Service in Oracle Cloud Infrastructure), it’s possible to deploy such instance with a compute instance hosting PHPMyAdmin very easily using OCI’s Resource Manager and a stack (zip file) that you can find here: https://github.com/lefred/oci-phpmyadmin-mds/releases/tag/1.1.0

If you want to try MDS in OCI, you can get free credits using this url: …

PHP provides a handy function, empty(), that is used to determine whether a variable is empty. Perhaps that is a bit confusing to someone unfamiliar with the empty() function and I can see how. In this blog post, I will cover: what empty() means in PHP, what the empty() function does, and a use case pairing up empty() with the PHP ternary operator conditional construct. Both used in combination with the MySQL NULL value. Continue reading and see examples of empty()…

In Use MySQL BLOB column with PHP to store .pdf file, I covered an example of how to store a .pdf file in the actual database table using the MySQL BLOB datatype and PHP. Now that we have .pdf’s stored in the database, how do we display them in the browser? This blog post answers that exact question. Continue reading to see a working example using PHP…

Like always I am sharing new things I learn here on my blog. I was recently working on a requirement for a LAMP stack web application reporting dashboard in which I needed to store – and eventually – retrieve a .pdf file. I have read in several places (this fantastic book is a great resource) that a viable option is storing images or documents (.pdf in this case) in the actual database table as opposed to on the server file system. MySQL has the BLOB datatype that can be used to store files such as .pdf, .jpg, .txt, and the like. In this blog post, I cover how I accomplished uploading and storing the actual .pdf file in a BLOB column in MySQL using PHP. Any corrections, tips, pointers, and recommendations for best practices are always welcome. We all learn as we go!!!

Using the MySQL ALTER TABLE command, you can easily change an existing columns’ name and datatype. With just a few clicks, you can do the same in the phpMyAdmin visual web interface. For many developers, this interface is the one they lean on most while programming so it can’t hurt to know how to do it yourself should you find yourself programming in this environment…

If you write MySQL queries, at some point you are going to have to provide query results in a specific order. To impose any ordering in MySQL (this applies to SQL overall and is not directed only at MySQL), you have to use the ORDER BY clause. Without it, there is no guaranteed order. The database is free to send back query results in any order. As I learn PHP, I make it a point to explore both the MySQL side, along with the PHP side in regards to similar type tasks and the efficiency of each. So far in my PHP journey, I have found that arrays are used quite extensively. In this post, I’ll cover array_multisort() – one of many in-built PHP functions – used for sorting arrays. In the context of the example data for this post, the arrays are populated by an unordered MySQL query. Let’s see one example of how you can establish a sorting order in a PHP …
