This post will give you example of How to Create Json File in php. This post will give you simple example of How to Generate Json File in php?. I would like to show you php Create Json File and Write. I would like to show you How to Save Json File in php?. Alright, let’s dive into the steps.

There ara two ways to create json file in php. in the first example, we will use fopen(), fwrite() and fclose() to create a json file. in the second example, we will use file_put_contents() to create json file in php.Let’s see both examples with output.

// Create Array for json file

$myArray = [

[ «id» => 1, «name» => «Hardik Savani», «email» => «hardik@gmail.com»], [ «id» => 2, «name» => «Jaydeep Pather», «email» => «jaydeep@gmail.com»], [ «id» => 3, «name» => «Vivek Pather», «email» => «vivek@gmail.com»]

];

// Create new data.json file

$fp = fopen(‘data.json’, ‘w’);

// Write data on json file

fwrite($fp, json_encode($myArray, JSON_PRETTY_PRINT));

// Close json file

fclose($fp);

print(«data.json File created successfully.»);

?>

After run successfully above example, you will see data.json file saved in your root path and file content will be as the below:

[

<

«id»: 1,

«name»: «Hardik Savani»,

«email»: «hardik@gmail.com»

>,

<

«id»: 2,

«name»: «Jaydeep Pather»,

«email»: «jaydeep@gmail.com»

>,

<

«id»: 3,

«name»: «Vivek Pather»,

«email»: «vivek@gmail.com»

]

// Create Array for json file

$myArray = [

[ «id» => 1, «name» => «Hardik Savani», «email» => «hardik@gmail.com»], [ «id» => 2, «name» => «Jaydeep Pather», «email» => «jaydeep@gmail.com»], [ «id» => 3, «name» => «Vivek Pather», «email» => «vivek@gmail.com»]

];

// Create json file from array

$data = json_encode($myArray);

file_put_contents(‘data.json’, $data);

print(«data.json File created successfully.»);

?>

After run successfully above example, you will see data.json file saved in your root path and file content will be as the below:

[

<

«id»: 1,

«name»: «Hardik Savani»,

Generate JSON File in PHP

In this article, we will introduce the method to generate a .json file in PHP.

Use file_put_contents() Function to Generate a .Json File in PHP

The built-in function file_put_contents() could write the content into a file in PHP. It searches for the file to write in, and if the desired file is not present, it creates a new file. We can use this function to create a .json file. The correct syntax to use this function is as follows

file_get_contents($pathOfFile, $info, $customContext, $mode); 

This function returns the number of bytes written on the file if successful and false otherwise.

The below program will create a new .json file and store JSON data into it

php  // data strored in array  $array = Array (  "0" => Array (  "id" => "01",  "name" => "Olivia Mason",  "designation" => "System Architect"  ),  "1" => Array (  "id" => "02",  "name" => "Jennifer Laurence",  "designation" => "Senior Programmer"  ),  "2" => Array (  "id" => "03",  "name" => "Medona Oliver",  "designation" => "Office Manager"  ) );  // encode array to json  $json = json_encode($array); $bytes = file_put_contents("myfile.json", $json); echo "The number of bytes written are $bytes."; ?> 

We use json_encode() function to convert the data stored in the array to a JSON string. Once the data is converted to a JSON string, file_put_contents() function creates a .json file and writes data into it. The output shows the number of bytes, which means the data is written successfully.

The number of bytes written is 207.
