for循环不断打印相同的信息

Question

我正在尝试打印 Zomato API 的数据。它打印第一个细节，然后打印第二个并不断重复第二个细节。我假设它不会在 1 之后增加 $i 的值，因此打印相同的细节。我做错了什么？

我的代码：

<?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';
echo 'API Call STRING ' . $api_call_string . '<br>';
$search = perform_api_call($api_call_string);
$res_high = array();

你在底部的循环中 re-assigning $i。我的猜测是内部循环只有 2 个元素，因此它会在每个循环中将 $i 重新分配给 1，使您陷入无限循环。

将内部循环变量的名称从 $i 更改为类似 $j

变化：

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

收件人：

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

for循环不断打印相同的信息

For loop keep printing the same information

php

api

for-loop
