将JSON从PHP返回到JavaScript？ [英] Returning JSON from PHP to JavaScript?

问题描述

我有一个通过jQuery AJAX调用的PHP脚本。我希望PHP脚本将JSON格式的数据返回给javascript。这是PHP脚本中的伪代码：

I have a PHP script that's being called through jQuery AJAX. I want the PHP script to return the data in JSON format to the javascript. Here's the pseudo code in the PHP script:

$json = "{";
foreach($result as $addr)
{
    foreach($addr as $line)
    {
        $json .= $line . "\n";
    }
    $json .= "\n\n";
}
$json .= "}";

基本上，我需要在$ json中插入两个for循环的结果。

Basically, I need the results of the two for loops to be inserted in $json.

推荐答案

Php具有内置的JSON序列化功能。

Php has an inbuilt JSON Serialising function.

json_encode

json_encode
