從joomla 2.5中的數組中獲取值

Question

我正在嘗試從數組中獲取值，這是我的代碼

print_r($new[1]->extra_fields);

結果是

 [{"id":"1","value":"compny name"},{"id":"2","value":"Dubai"}, {"id":"3","value":"UAE"},{"id":"4","value":"2014-07-31"},{"id":"5","value":"AED 12000"}]</p> 

我如何分別獲取特定的值，如公司名稱，迪拜，AED 12000

Answer 1

您在變量中有json字符串

foreach(json_decode($new[1]->extra_fields, true) as $field){ // true for assoc value array
   print_r($field);
   print($field['id']);
   print($field['value']);
}

編輯：公司名稱

foreach(json_decode($new[1]->extra_fields, true) as $field){ // true for assoc value array
   print_r($field);
   if($field['id'] == "1"){
       $comp_name = $field['value'];break;
   }
}

Answer 2

您需要將其用作

$extra_fields = json_decode($new[1]->extra_fields); // use json_decode, as value is json encoded
foreach($extra_fields as $field){
   echo $field->value;
}
