How to Convert XML to Array in PHP Easily

As a developer working with SOAP APIs, you may find yourself needing to convert XML responses into a more manageable format, such as an array. This transformation is crucial for accessing keys and utilizing the data effectively in your applications. In this guide, we will provide a step-by-step guide on how to convert XML to an array in PHP, making it simpler to process API responses.

The Problem

You have received an XML response from a SOAP API and are unable to extract the data efficiently. For instance, consider the following XML structure returned from the web services:

You may be asking yourself: How do I convert this XML into an array format to easily access the data?

The Solution

Let's break down the process of converting your XML to an array in PHP.

Step 1: Receive the XML Response

Assuming you have captured the XML response in a variable (e.g., $response), we start by processing this string.

Step 2: Clean up the XML

Sometimes, namespaces in the XML can cause issues during parsing. To handle this, you'll want to use a regular expression to remove the namespaces:

This line of code replaces the namespaced elements with clean names, enabling easier handling.

Step 3: Load the XML

Next, we will use PHP's simplexml_load_string() function to create an object from the cleaned XML string:

Step 4: Convert to JSON and then to Array

Since PHP can natively convert objects to JSON, we will first encode the XML object to JSON. Then, we will decode this JSON back to an associative array using json_decode():

Step 5: Output the Array

Now, you can easily check the structure and data of your newly created array:

Conclusion

With the steps outlined above, you can now easily convert XML responses from SOAP APIs to an array format in PHP. This conversion facilitates easier data manipulation and access, allowing developers to work more effectively with API responses.

Remember, understanding how to manipulate data formats is essential in the development process, especially in web services and API integration. Happy coding!
