PHP has some built-in functions to handle JSON. Objects in PHP can be converted into JSON by using the PHP function json_encode():
PHP file
<?php
$data->name = "John";
$data->age = 30;
$data->city = "New York";
echo $json_data = json_encode($data);
?>
Result:
{"name":"John","age":30,"city":"New York"}
JSON Array PHP
$age = array("Peter"=>35, "Ben"=>37, "Joe"=>43);
echo json_encode($age);Result:
{"Peter":35,"Ben":37,"Joe":43}
