You can create JSON files from PHP arrays using the json_encode function. Here's an example of how you can create a JSON file from 3 PHP arrays:

<?php

// Sample PHP arrays
$firstArray = array(
    'name' => 'John Doe',
    'age' => 30,
    'city' => 'New York'
);

$secondArray = array(
    'name' => 'Jane Smith',
    'age' => 25,
    'city' => 'Los Angeles'
);

$thirdArray = array(
    'name' => 'Michael Johnson',
    'age' => 35,
    'city' => 'Chicago'
);

// Combine all arrays into one
$combinedArray = array(
    'users' => array($firstArray, $secondArray, $thirdArray)
);

// Convert the combined array to JSON format
$jsonData = json_encode($combinedArray);

// Write JSON data to a file
$filename = 'users.json';
file_put_contents($filename, $jsonData);

echo 'JSON file created successfully';
?>


This script will combine the 3 PHP arrays into a single array and convert it to JSON format using json_encode. Then, it will write the JSON data to a file named users.json. You can modify the content of the arrays and the file name to suit your needs.
