Transforming MySQL Query Results to an Array String in PHP

When you're working with databases in PHP, you often need to pull data in a format that's easy to manipulate. One common task is converting the results of a MySQL query into an array string. This can simplify how you handle your data in various scenarios. In this guide, we’ll explore how to achieve this transformation effectively using PHP.

The Problem

Suppose you have a MySQL query that retrieves a list of account numbers (no_rekening) from a database table (tbl_rekening). Here’s the initial SQL query structure you might use:

Upon executing this code, you get a result that looks like this:

However, the goal is to convert it to a more structured format like:

Why Is This Important?

Formatting your data as an array string is crucial for several reasons:

Easier Manipulation: It allows you to easily access and manipulate individual elements.

Improved Readability: Structured data is easier for humans to read and understand.

Interoperability: Properly formatted strings can be used in JSON or other data formats seamlessly.

The Solution

Now that we understand both the goal and its importance, let’s break down the solution step by step. We’ll modify the code to correctly format the query results into the desired array string.

Step 1: Fetching the Data

You need to make sure that the data is being fetched correctly from your tbl_rekening. Also, ensure to declare your $rek_array variable correctly and initialize it.

Step 2: Building the Array String

As you fetch the results from the query, instead of appending them directly, you'll want to add each value followed by a comma. Additionally, it's beneficial to wrap each fetched value in quotes. Here’s how you can do that:

Step 3: Removing the Trailing Comma

Once you have appended all your values, you will end up with an extra comma at the end of your string. This can be easily fixed using the substr() function to remove the last character:
