使用 Yelp API 的 PHP 解析 JSON 响应

Question

I can't seem to parse information sent by the Yelp API. Here's the output: http://www.coroomer.com/apartments/yelp.php .

Here is the segment of the code I am having trouble with:

// Send Yelp API Call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $signed_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
$response = curl_exec($ch);
curl_close($ch);

// Handle Yelp response data
$obj = json_decode($response,true);

// Print it for debugging
//print_r($obj);

echo var_dump($obj);

if (isset($bus)) {
foreach($obj[businesses] as $bus){
    echo $bus[name];
    echo $bus[reviews];
    }
}

The problem is that I can't get a correctly "formatted" output. Formatted as in it looks like the review threads on Yelp. Any help is appreciated.

Answer 1

It's not clear what exactly you are asking. However...

1. Fix your warnings and notices first. Do not try to access arrays without single or double quotes around indexes, because PHP will try to resolve them as CONSTANTS. Which will lead to:

a. Slower runtime

b. Headaches, if a constant exists with that index

Change this code:

foreach($obj[businesses] as $bus){
    echo $bus[name];
    echo $bus[reviews];

to

foreach($obj['businesses'] as $bus){
    echo $bus['name'];
    echo $bus['reviews'];

2. The dump doesn't have any array with the index businesses , what are you trying to iterate over here?
