PHP Get, Write, Read, Load, JSON Data from URL

JSON (JavaScript Object Notation) is a lightweight data interchange format that is widely used in web development. In PHP, we can easily retrieve, write, read, load JSON data from a URL using various built-in functions and libraries. In this article, you will learn how to perform these operations in PHP.

How to Get, Write, Read, Load, JSON Data from URL in PHP

Use the following examples to get, read, write and load json data from url or apis in php; as follows:

1. PHP read JSON file From URL
2. Get JSON File Data From URL in PHP & Convert JSON to Array PHP
3. Convert JSON to Object PHP
4. PHP write or save JSON to a JSON file
Loading JSON Data from a File in PHP

1. PHP read JSON file From URL

You can use the PHP file_get_contents() function that is used to get or read or load file from the given path (Url or Source).

To get JSON data from a URL in PHP, we can use the “file_get_contents” function along with the “json_decode” function. Here’s an example:

$filename = 'data.json';
$data = file_get_contents($filename);
$jsonData = json_decode($data);

In this code snippet, you first specify the filename of the JSON data that we want to read. Then, you use the “file_get_contents” function to retrieve the data from the file. Finally, you use the “json_decode” function to convert the JSON data into a PHP object.

2. Get JSON File Data From URL in PHP & Convert JSON to Array PHP

You can use the file_get_contents() function and json_decode() function of PHP.

File get_get_conents() get that is used to get or read file from the given path (Url or Source).
json_decode() function of PHP, which is used to convert JSON file contents to PHP Array

$url = 'https://example.com/data.json';
$data = file_get_contents($url);
$jsonData = json_decode($data);

In this code snippet, you first specify the URL of the JSON data that you want to retrieve. Then, you use the “file_get_contents” function to retrieve the data from the URL. Finally, you use the “json_decode” function to convert the JSON data into a PHP object.

3. Convert JSON to Object PHP

You can convert JSON file data to the PHP objects. You can use the json_decode() without passing the TRUE in it. Because by default, the PHP json_decode function will convert the JSON data into an object.

<?php

$url = 'your json file path';

//read json file from url in php
$readJSONFile = file_get_contents($url);

//convert json to array in php
$array = json_decode($readJSONFile);
var_dump($array); // print array

?>

4. PHP write or save JSON to a JSON file

You can use the file_put_contents() function of PHP, which is used to write or save data from a given path of the JSON file or text file.

$url = 'https://example.com/data.json';
$data = array('name' => 'John Doe', 'age' => 30, 'city' => 'New York');
$jsonData = json_encode($data);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

echo $response;

In this code snippet, you first specify the URL of the JSON data that we want to write to. Then, you create an array of data that you want to write to the URL and convert it into a JSON string using the “json_encode” function. Then, you use the “curl_init” function to initialize a curl session, set the request method to PUT, and set the JSON data as the request payload. Finally, you execute the curl session, retrieve the response, and close the session.

5. Loading JSON Data from a File in PHP

To load JSON data from a file in PHP, we can use the “json_decode” function. Here’s an example:

$filename = 'data.json';
$data = file_get_contents($filename);
$jsonData = json_decode($data);

In this code snippet, you first specify the filename of the JSON data that you want to load. Then, you use the “file_get_contents” function to retrieve the data from the file. Finally, you use the “json_decode” function to convert the JSON data into a PHP object.

Conclusion

JSON data is a popular data interchange format in web development. In PHP, you can easily retrieve, write, read, and load JSON data from a URL or a file using various built-in functions and libraries. By understanding these techniques, developers can leverage the power of JSON data in their PHP applications.
