Php json数组正在重复索引

这是我的代码：

if ($API->connect("192.168.81.130", "admin", "")) {
    $API->write('/ip/route/print', false);
    $API->write('=.proplist=.id', false);
    $API->write('=.proplist=dst-address', false);
    $API->write('=.proplist=pref-src', false);
    $API->write('=.proplist=gateway');
    $result = $API->read();
    $API->disconnect();

    foreach ($result as $route){
        $response['id'] = $route['.id'];
        $response['dst-address'] = $route['dst-address'];
        if (isset($route['pref-src'])) {
            $response['pref-src'] = $route['pref-src'];
        } else {
            $response['pref-src'] = "";
        }
        $response['gateway'] = $route['gateway'];
        $array[] = $response;
        echo json_encode($array);
    } 
}   

输出为：

[{"id":"*2","dst-address":"0.0.0.0\/0","pref-src":"","gateway":"192.168.1.1"}][{"id":"*2","dst-address":"0.0.0.0\/0","pref-src":"","gateway":"192.168.1.1"},{"id":"*420639B3","dst-address":"192.168.81.0\/24","pref-src":"192.168.81.130","gateway":"ether1"}]

“[{”id:“*2”，“dst地址:“0.0.0.0/0”，“pref src:”“网关:“192.168.1.1”}]”的结果显示两次

我想要这样的输出：

> [{"id":"*2","dst-address":"0.0.0.0\/0","pref-src":"","gateway":"192.168.1.1"},{"id":"*420639B3","dst-address":"192.168.81.0\/24","pref-src":"192.168.81.130","gateway":"ether1"}].

有人能帮我吗？

您需要在每次循环中初始化阵列，否则每次都只是添加到阵列中，因此会出现重复

您还需要将json字符串的回显移动到循环外部

foreach ($result as $route){
    $response = array();

    $response['id'] = $route['.id'];
    $response['dst-address'] = $route['dst-address'];
    if (isset($route['pref-src'])) {
        $response['pref-src'] = $route['pref-src'];
    } else {
        $response['pref-src'] = "";
    }
    $response['gateway'] = $route['gateway'];
    $array[] = $response;

} 
echo json_encode($array);

您的第一个输出有语法错误，这是出于设计吗？另外，为什么不直接进行

json\u编码（array\u unique（$array））

？这将消除所有重复项。它显示错误“数组到字符串转换”@GrumpyCroutonThank@RiggsFolly当我移动回显并初始化数组以避开循环时，它会工作。
