How to Convert a PHP Array to a JSON Array Using `json_encode()`?

How to Convert a PHP Array into a JSON Array

To create a JSON array from a PHP array, utilize the json_encode() function. This function transforms the PHP array into a JSON representation.

Example:

Consider the following PHP array:

$arr = [
  ["region" => "valore", "price" => "valore2"],
  ["region" => "valore", "price" => "valore2"],
  ["region" => "valore", "price" => "valore2"],
];

To convert this PHP array into a JSON array, use json_encode():

$json = json_encode($arr);

The output $json will be:

[
  {"region":"valore","price":"valore2"},
  {"region":"valore","price":"valore2"},
  {"region":"valore","price":"valore2"}
]
