PHP：来自API的JSON数据

Here's an example (I did alter the values) of JSON data that I'm getting from an API:

{"status":"OK","data":{"trends":{"uv":[{"date":"201303","value":1},{"date":"201304","value":2},{"date":"201305","value":31},{"date":"201306","value":4},{"date":"201307","value":4},{"date":"201308","value":9},{"date":"201309","value":12},{"date":"201310","value":43},{"date":"201311","value":14},{"date":"201312","value":73},{"date":"201401","value":78},{"date":"201402","value":65},{"date":"201403","value":52}]},"trends_low_sample":false,"query_cost":13,"trends_frequency":"monthly"}}

How would go about accessing the value in data.trends.uv[number_the_array].date in PHP?

Here's some stuff I've played around with:

$data1 = file_get_contents('/home/strj500/Downloads/result.html');
//echo $data1;

$theData = json_encode($data1);

//$data1 = preg_replace('/,\s*([\]}])/m', '$1', utf8_encode($data1));

//$data1 = utf8_encode($data1);

$result1 = json_decode($theData);

echo $result1->status;

//var_dump($result1);

//echo json_last_error();

//echo error_log();

//echo error_reporting(E_ALL);

/*foreach ($result1->data->trends->rank as $rank
{
    echo "{$rank->date}
";
}*/

//echo $result1["data"]["trends"]["uv"];

Maybe another question that goes along with this, if I'm wanting to access JSON later in PHP, what's the best file format to store it in? (JSON, TXT, HTML)? If it helps I'm also going to be passing this json data on mysql.

Loop like this..

<?php
$json='{"status":"OK","data":{"trends":{"uv":[{"date":"201303","value":1},{"date":"201304","value":2},{"date":"201305","value":31},{"date":"201306","value":4},{"date":"201307","value":4},{"date":"201308","value":9},{"date":"201309","value":12},{"date":"201310","value":43},{"date":"201311","value":14},{"date":"201312","value":73},{"date":"201401","value":78},{"date":"201402","value":65},{"date":"201403","value":52}]},"trends_low_sample":false,"query_cost":13,"trends_frequency":"monthly"}}';
$yourobj=json_decode($json);
foreach($yourobj->data->trends->uv as $k=>$arr)
{
    echo $arr->date."<br>";
}

OUTPUT:

Demo

By using json_decode() with the second parameter as true:

$result1 = json_decode($theData,true);

You will be able to access all the elements as normal arrays. If you want to fetch some specific data for example you could do it as so (In this example we want the index 0):

$result1['data']['trends']['uv'][0];
