apache_request_headers() 使用 PHP

问题描述

我做了一个 JSON 调用并返回它：

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL,'https://www.example.com/sdfsldfsd3/all-result.json');
curl_setopt($ch,CURLOPT_HTTPHEADER,array('AccessKey: 
dasdasdq312312qWQEQ'));
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

$headers = apache_request_headers();

foreach ($headers as $header => $value) {
    echo "$header: $value <br />\n";
}  
$json = curl_exec($ch);
curl_close($ch);

现在我想显示标题的前 5 个值：

string(906287) "{"data":[{"id":12238,"title":"Title no 1"},{"id":7510,"title":"Title no 2"},etc.

我应该如何显示如下结果：

<a href=page.PHP?id=12238>Title no 1</a> <br>
<a href=page.PHP?id=7510>Title no 2</a> <br> etc

提前致谢

工作代码：

$json = curl_exec($ch);
$data = json_decode($json);

foreach ($data->data as $key => $row) {
    if ($key === 5) break; 
        echo '<a href=page.PHP?id=' . $row->id . '>' . $row->title . '</a> <br>';
    }
}

解决方法

如果您需要写下所有链接，只需使用

<?php

$str = '{"data":[{"id":12238,"title":"Title no 1"},{"id":7510,"title":"Title no 2"}]}';
$data = json_decode($str);

foreach ($data->data as $row) {
    echo '<a href=page.php?id=' . $row->id . '>' . $row->title . '</a> <br>';
}

如果您只需要 5 个链接，foreach 就是

foreach ($data->data as $key => $row) {
    if ($key === 5) break;

    echo '<a href=page.php?id=' . $row->id . '>' . $row->title . '</a> <br>';
}
