PHP Read JSON File

PHP Read JSON File

In this article we will show you the solution of PHP read JSON file, a common file format for exchanging data among applications is JSON (JavaScript Object Notation). To translate (decode) the string into a PHP associative array, we use json decode.

It is possible to read a file and retrieve the data contained in a JSON file using the PHP function file_get_contents().

After data retrieval, the JSON format needs to be converted to an array format. The information will then be shown as a tabular format using a looping statement.

It is known that nested data structures relate to arrays or objects that contain references to those other arrays or objects because these types of data structures are the values. Such structures can be accessed by using brackets or dots. JSON can be found in file format.

They have names along the lines of VitalLogicData.json. Despite having well-formatted data in JavaScript Object Notation, it is really a text file. These files can naturally also be appended to or read from.

Square brackets are used to access the multidimensional array; first, an element from of the outer array is accessed, returning an element from of the inner array; next, an element from of the inner array is accessed, returning an element from of the outer array.

Since a JSON string in PHP is largely meaningless, we can loop over it and perform interesting operations on the data if we convert it to an array.

You could wish to output it as an HTML table or store it in a database.

Whatever you intend to do, you must first parse the data into an array.

To accomplish this, we utilise json_decode, which converts JSON data into an associative array using a clever Boolean option.

Step By Step Guide On PHP Read JSON File :-

$json = file_get_contents('my_data.json');
$json_data = json_decode($json,true);
  1. Short tags begin with a "?" and end with a "?>". Only when short style tags are enabled in a server's php.ini configuration file are they available.
  2. After that, the JSON file is read and decoded.
  3. The data is then displayed and printed in the programme.

Conclusion :-

JSON, and the JavaScript Object Notation, is a widely used, lightweight method of storing and exchanging data.

It was derived from JavaScript, as the name suggests, but it's a language-independent data storage format.

JSON data reading and writing functions are now available in very many computer languages, including PHP.

I hope this article on PHP read JSON file helps you and the steps and method mentioned above are easy to follow and implement.
