Preferred way to parse PHP arrays into JSON

Two preferred ways to convert PHP arrays to JSON: Using the json_encode function: Provides encoding control and flexible options. Use a combination of serialize and base64_encode functions: good for special cases, but not as straightforward as json_encode.

The preferred method to parse a PHP array into JSON

There are several methods available when converting a PHP array into JSON choose. In this article, we will explore two preferred methods and illustrate them with practical examples.

Using the json_encode function

json_encode function is a built-in function that encodes a PHP array to JSON. It provides flexible control over the encoding process and supports various options.

<?php
// 准备 PHP 数组
$arr = array(
    "name" => "John Doe",
    "age" => 30,
    "email" => "john.doe@example.com"
);

// 使用 json_encode 函数编码数组
$json = json_encode($arr);

// 打印编码后的 JSON 字符串
echo $json;
?>

Output:

{"name":"John Doe","age":30,"email":"john.doe@example.com"}

Using the serialize and base64_encode functions

Although the json_encode function is the standard way to parse an array into JSON, for some special cases, we may also need to use a combination of the serialize and base64_encode functions.

<?php
// 准备 PHP 数组
$arr = array(
    "name" => "John Doe",
    "age" => 30,
    "email" => "john.doe@example.com"
);

// 使用 serialize 函数序列化数组
$serialized = serialize($arr);

// 使用 base64_encode 函数对序列化后的数据进行编码
$json = base64_encode($serialized);

// 打印编码后的 JSON 字符串
echo $json;
?>

Output:

Notes

• When using the json_encode function, Make sure the values ​​in the array are JSON valid and do not contain special characters or Unicode values.
• While it is possible to encode an array into a JSON string using the serialize and base64_encode functions, it is not as direct and intuitive as the json_encode function.
