방법 서버 측에서 'mode_1', PHP 페이지에 대한 값을 읽을 수 있습니다

$.ajax({ 
    url: 'php_scripts/reload_fancoils.php', 
    type: 'POST', 
    dataType: 'json', 
    data:parameters, 
    success: function(data){ 
     //alert(data); 
     console.log(data); 
    }, 
    error:function (xhr, ajaxOptions, thrownError){ 
     alert('statusText='+xhr.statusText+' responseText='+xhr.responseText); 
    } 

}); 

같은 요청?

Answer 1

$plan = json_decode($_POST['plan']); 
$mode1 = $plan->modes->mode_1; 

Answer 2

사용 json_decode 함수, 예를 들면

$var = json_decode($_POST['parameters']); 

var_dump($var);
