怎样使用php获取复杂json数据并输出
这是调用多客服查看当前在线客服时的微信api

返回数据示例(正确时的JSON返回结果):

{<br />    "kf_online_list": [<br />        {<br />            "kf_account": "[email&#160;protected]",<br />            "status": 1,<br />            "kf_id": "1001",<br />            "auto_accept": 0,<br />            "accepted_case": 1<br />        },<br />        {<br />            "kf_account": "[email&#160;protected]",<br />            "status": 1,<br />            "kf_id": "1002",<br />            "auto_accept": 0,<br />            "accepted_case": 2<br />        }<br />    ]<br />}


以下是我的代码:

$url_online ="https://api.weixin.qq.com/cgi-bin/customservice/getonlinekflist?access_token={$access_token}";<br />$output_online=file_get_contents($url_online);<br />$jsonStr = json_decode($output_online,true);<br />//读取信息:<br />$content = "客服1:".$jsonStr["kf_online_list"]["kf_account"]."\n在线状态:".$jsonStr["kf_online_list"]["status"]."\n正在接待人数:".$jsonStr["kf_online_list"]["accepted_case"]."\n\n客服2:".$jsonStr["kf_online_list"]["kf_account"]."\n在线状态:".$jsonStr["kf_online_list"]["status"]."\n正在接待人数:".$jsonStr["kf_online_list"]["accepted_case"];<br />?>


我本是希望获得所有的kf_account数据,并返回到微信回话界面,可是这结构有点复杂,还有相同的字段。。。
目前还查询不到结果,我估计是最后获取json的数组写的不对,希望大家帮忙!
------解决思路----------------------
$s =<<< JSON
{<br /> "kf_online_list": [<br /> {<br /> "kf_account": "[email&#160;protected]",<br /> "status": 1,<br /> "kf_id": "1001",<br /> "auto_accept": 0,<br /> "accepted_case": 1<br /> },<br /> {<br /> "kf_account": "[email&#160;protected]",<br /> "status": 1,<br /> "kf_id": "1002",<br /> "auto_accept": 0,<br /> "accepted_case": 2<br /> }<br /> ]<br />}
JSON;
$jsonStr = json_decode($s, true);

$content = '';
foreach($jsonStr['kf_online_list'] as $i=>$item) {
$n = $i + 1;
$content .= "
客服{$n}:$item[kf_account]
在线状态:$item[status]
正在接待人数:$item[accepted_case]
";
}
echo $content;
<br />客服1:[email&#160;protected]<br />在线状态:1<br />正在接待人数:1<br /><br />客服2:[email&#160;protected]<br />在线状态:1<br />正在接待人数:2<br /><br />

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
