PHP JSon如何读取以JSon格式接收的布尔值并在PHP上以字符串形式写入

我从另一个站点接收到此JSON字符串,并且无法修改接收自的字符串。该字符串在$ _POST中接收,为:

[

{

"clientId":"17295c59-4373-655a-1141-994aec1779dc",

"channel":"\/meta\/connect",

"connectionType":"long-polling",

"ext":{

"fm.ack":false,

"fm.sessionId":"22b0bdcf-4a35-62fc-3764-db4caeece44b"

},

"id":"5"

}

]

我使用以下代码解码JSON字符串:

$receive = json_decode(file_get_contents('php://input'));

当我使用时,print_r($receive)我得到以下信息:

Array (

[0] => stdClass Object

(

[clientId] => 17295c59-4373-655a-1141-994aec1779dc

[channel] => /meta/connect

[connectionType] => long-polling

[ext] => stdClass Object

(

[fm.ack] =>

[fm.sessionId] => 22b0bdcf-4a35-62fc-3764-db4caeece44b

)

[id] => 5

)

)

我可以毫无问题地访问和读取所有数组/对象:

$receive[$i]->clientId;

$receive[$i]->channel;

$connectionType = $receive[$i]->connectionType;

$receive[$i]->id;

$receive[$i]->ext->{'fm.sessionId'};

但是{fm.ack}为空

在解码的JSON字符串中,假值不在之间""

是否可以访问和读取错误值并将其转换为字符串值?

谢谢您的帮助!

回答:

您可以像这样使用它,其JSON格式为:当您评估false价值时将给您blank,而当您评估价值true将给您1

$str = '[{"clientId":"17295c59-4373-655a-1141-994aec1779dc","channel":"\/meta\/connect","connectionType":"long-polling","ext":{"fm.ack":false,"fm.sessionId":"22b0bdcf-4a35-62fc-3764-db4caeece44b"},"id":"5"}]';

$arr = json_decode($str,true);

if($arr[0]['ext']['fm.ack']) // suggested by **mario**

{

echo "true";

}

else {

echo "false";

}
