How to Read JSON File in Laravel 10

Laravel 10 is a powerful web application framework used to develop web applications quickly. It has powerful features that make it an ideal choice for web developers. One such feature is the ability to read JSON files.

JSON (JavaScript Object Notation) is a lightweight data-interchange format which is both human-readable and machine-readable. It is commonly used for transferring data between different applications and web services.

This article explains how to read JSON files in Laravel 10, a popular PHP framework for web development. It covers the steps required to load and parse JSON data using built-in functions in Laravel, including reading the file, decoding the data, and accessing the JSON objects and arrays. The article is aimed at developers who are new to Laravel or want to learn how to work with JSON files in the framework.

Step 1: Create a JSON File

First, we need to create a JSON file. For this tutorial, we will create a sample.json file inside the public directory. Inside the sample.json file, add the following code:

{
    "name": "John Doe",
    "age": 30,
    "location": "San Francisco"
}

Step 2: Read the JSON File

Now that we have our JSON file created, we can now read it using Laravel 10. In order to read the JSON file, we need to use the File class provided by Laravel. We can use the get() method of the File class to read the contents of the file.

$json = \File::get('sample.json');

Step 3: Decode the JSON File

The contents of the JSON file are returned as a string. We need to convert the string into an array in order to access the data.

To do this, we can use the json_decode() function provided by PHP. This function takes the JSON string as an argument and returns an array of the data.

$data = json_decode($json);

Step 4: Access the Data

Now that we have the data in an array, we can access it by using the array syntax.

For example, to access the name field, we can use the following code:

echo $data['name']; // John Doe

Conclusion

In this tutorial, we have seen how to read JSON files in Laravel 10. We have also seen how to access the data from the JSON file.

Reading JSON files in Laravel 10 is a great way to transfer data between different applications and web services.
