如何使用 PHP 为 JSON 创建一个数组?

From PHP code I want to create an json array:

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

How can I do this?

Easy peasy lemon squeezy: http://www.php.net/manual/en/function.json-encode.php

<?php
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);

echo json_encode($arr);
?>

There's a post by andyrusterholz at g-m-a-i-l dot c-o-m on the aforementioned page that can also handle complex nested arrays (if that's your thing).
