从joomla 2.5中的数组中获取值

Question

我试图从数组中获取值是我的代码

    print_r($new[1]->extra_fields);

结果是

[{"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>

如何单独获取特定值，如公司名称，迪拜，AED 12000

Answer 1

  

你在变量

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']);
}

编辑：公司名称

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

您需要将其用作

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