For 循环不断打印相同的信息

Question

I am trying to print the data of Zomato API. It prints the first detail, then second and keep repeating the second detail. I am assuming its not increasing the value of $i after 1 hence printing the same details. What am I doing wrong?

My code:

<?php
// Errors on
error_reporting(E_ALL);
?>

<h1>Testing of Zomato API Code</h1>

<?php
function perform_api_call($param)
{
    // Get cURL resource
    $curl = curl_init();
    // Curl options
    curl_setopt_array($curl, array(
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HTTPHEADER => ['Accept: application/json',
        'user-key:' . '*******'],
        CURLOPT_URL => 'https://developers.zomato.com/api/v2.1/' . $param,
    ));
    // Send the request & save response to $resp
    $resp = curl_exec($curl);
    // Check for errors if curl_exec fails
    if (!curl_exec($curl))
    {
        die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
    }
    // Close request to clear up some resources
    curl_close($curl);
    // Decode json
    return json_decode($resp, true);
}

echo '<h2>Perform the search</h2>';
$api_call_string = 'search?entity_type=city&q=Brisbane';

$search = perform_api_call($api_call_string);

Answer 1

You're re-assigning $i within the loop at the bottom. My guess is the inner loop only has 2 elements so it keep reassigning $i to 1 every loop putting you in an indefinite loop.

Change the name of the inner loop variable from $i to something like $j

Change:

for ($i = 0;$i < count($reviews['user_reviews']);$i++)
    {
        $userreview = $reviews['user_reviews'][$i]['review']['review_text'];
        echo 'user review = ' . $userreview;
        echo '***************************************';
    }

To:

for ($j = 0;$j < count($reviews['user_reviews']);$j++)
    {
        $userreview = $reviews['user_reviews'][$j]['review']['review_text'];
        echo 'user review = ' . $userreview;
        echo '***************************************';
    }
