如何使用PHP为JSON创建数组?

2022-08-30 06:55:09

从PHP代码中,我想创建一个json数组:

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

我该怎么做?

易榨柠檬: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);
?>

在上述页面上有一个帖子,也可以处理复杂的嵌套数组(如果这是你的事情)。andyrusterholz at g-m-a-i-l dot c-o-m

使用 PHP 的本机json_encode,如下所示:

<?php
$arr = array(
    array(
        "region" => "valore",
        "price" => "valore2"
    ),
    array(
        "region" => "valore",
        "price" => "valore2"
    ),
    array(
        "region" => "valore",
        "price" => "valore2"
    )
);

echo json_encode($arr);
?>

更新:在评论中回答您的问题。你这样做是这样的:

$named_array = array(
    "nome_array" => array(
        array(
            "foo" => "bar"
        ),
        array(
            "foo" => "baz"
        )
    )
);
echo json_encode($named_array);
