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

  • 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.

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.

How to Write JSON to File in PHP

Hi! In this post we’ll see how to write json to file in php. JSON formatted data is more verbose and human readable. If you want to store data which is easily processable in the future, then json format would be a preferable choice nowadays. In the past I have written several tutorials about handling json data and some of the blog readers asked for a solution to save the json data in a file. I thought writing a separate tutorial on the topic will benefit everyone. Here I have given the php script to write json formatted string to file.

Write JSON to File in PHP

The below php script takes up an multi-dimensional associative array, encode it into json string and then write it into a file.

 Array ( "id" => "MMZ301", "name" => "Michael Bruce", "designation" => "System Architect" ), "1" => Array ( "id" => "MMZ385", "name" => "Jennifer Winters", "designation" => "Senior Programmer" ), "2" => Array ( "id" => "MMZ593", "name" => "Donna Fox", "designation" => "Office Manager" ) ); // encode array to json $json = json_encode(array('data' => $array)); //write json to file if (file_put_contents("data.json", $json)) echo "JSON file created successfully. "; else echo "Oops! Error creating json file. "; // data.json // <"data":[<"id":"MMZ301","name":"Michael Bruce","designation":"System Architect">,,]> ?>
  • The function json_encode(array(‘data’ => $array)) encodes array to json along with a name «data».
  • The function file_put_contents(«data.json», $json) writes/stores $json string to the specified file «data.json».
  • Convert CSV File to JSON using PHP

As web applications and APIs have become more popular and complex over the years, so has the demand for data formats that can be easily read and written by both machines and humans. JSON, or JavaScript Object Notation, is one such format that has gained widespread adoption due to its simplicity, flexibility, and human-readability. In this article, we will explore how to write JSON data to a file in PHP, a popular server-side scripting language used for web development.

Using json_encode() to Encode an Array to JSON

Before we can write JSON data to a file in PHP, we need to first encode an array to JSON format using the json_encode() function. This function takes an array as input and returns a JSON string that can be easily written to a file. Here’s an example code snippet:

$data = array('name' => 'John', 'age' => 30, 'city' => 'New York'); $json = json_encode($data); 

In the above example, we first create an array called $data with three key-value pairs representing a person’s name, age, and city. We then pass this array to the json_encode() function, which returns a JSON string that looks like this:

Writing JSON Data to a File Using fopen() and fwrite() Functions

Now that we have our JSON string, we can write it to a file using the fopen() and fwrite() functions. The fopen() function is used to create a file handle, which we can then pass to the fwrite() function along with our JSON string. Here’s an example code snippet:

$file = fopen('data.json', 'w'); fwrite($file, $json); fclose($file); 

In the above example, we first create a file handle called $file using the fopen() function. We pass two arguments to this function — the name of the file we want to create ( data.json ), and the mode in which we want to open the file ( w , which stands for “write»). We then pass our JSON string to the fwrite() function along with the file handle, which writes the string to the file. Finally, we close the file handle using the fclose() function.

Checking Write Permissions and Using Absolute Path

When writing to a file in PHP, it’s important to check that the directory where the file will be created has write permissions. This can be done using the is_writable() function. Additionally, it’s a good practice to use an absolute path to the file to avoid errors. Here’s an example code snippet:

In the above example, we use the is_writable() function to check if the directory /path/to/dir has write permissions. If it does, we create a file handle called $file using an absolute path to the file ( /path/to/dir/data.json ) and write our JSON string to the file using the fwrite() function.

Decoding JSON Data Using json_decode() Function

In addition to Writing JSON Data to a file, we may also need to read JSON data from a file and decode it into a PHP object or an associative array. This can be done using the json_decode() function. Here’s an example code snippet:

$json = file_get_contents('data.json'); $data = json_decode($json, true); 

In the above example, we first use the file_get_contents() function to read the contents of the file data.json into a variable called $json . We then pass this variable to the json_decode() function along with a second argument ( true ) to indicate that we want the JSON string to be decoded into an associative array. The resulting array can then be used like any other PHP array.

Using file_put_contents() Function to Write Data to a File

Finally, we can also use the file_put_contents() function to write data to a file in a single line of code. This function takes two arguments — the name of the file we want to create or overwrite, and the data we want to write to the file. Here’s an example code snippet:

file_put_contents('data.json', $json); 

In the above example, we simply pass the name of the file we want to create ( data.json ) and our JSON string to the file_put_contents() function, which writes the string to the file.
