Resolving HTTP Query String Encoding Issues in PHP

When working with PHP, handling data structures like JSON can sometimes get tricky, especially when you need to transform them into query strings for HTTP requests. A common problem developers face is dealing with unwanted encoding characters when using the http_build_query() function. If you've encountered this issue, you're not alone! In this guide, we'll explore a practical solution to convert a JSON array of objects into a properly formatted HTTP query string without encoding problems.

The Problem

Let's take a look at a typical scenario where this issue arises. Suppose you have a JSON array that looks like this:

Your goal is to convert this JSON into an HTTP query string formatted like so:

However, when you attempt to use PHP's http_build_query() function, you might find that the output includes unwanted encoding characters, returning something like this:

This output is not what you want! The issue stems from how PHP handles associative arrays in combination with the http_build_query() function.

The Solution

To tackle this problem effectively, we can break the solution down into several manageable steps. The goal here is to manually build the query string while ensuring that we properly format each key-value pair without unnecessary encoding characters.

Step 1: Decode the JSON

First, decode the JSON array into a PHP variable. This can be accomplished using the json_decode() function. Here’s how:

Step 2: Initialize Variables

You'll want to set up a variable to store your query string. Additionally, a counter will help us determine when to prepend a '?' versus a '&'.

Step 3: Loop Through the Array

Next, iterate over each item in the decoded JSON array. Within that loop, you'll want to grab each key-value pair and add it to your query string.

Step 4: Output the Result

Finally, simply echo the resulting string. Your final output should look like this:
