Question

include('Property.php');
$obj = new Property ();
$obj->price = 2500.00;
$obj ['address_primary'] = '100 Main St';
$obj->state = 'VA';
echo 'Address :: ', $obj->address_primary, ' ', PHP_EOL;
echo 'City, State, Zip :: ', $obj ['state'];

可以请有人向我解释如何：从$ obj = new Property（）我们可以创建/初始化或者：$ obj ['address_primary']并且能够回应这个：$ obj-＆gt; address_primary

抱歉，我尽可能多地解释这个问题。谢谢你的回答伙计!!

Answer 1

您正尝试将属性作为数组元素进行访问。您需要扩展ArrayObject。 http://php.net/manual/en/class.arrayobject.php这样做。否则不要混合对象和数组。

Answer 2

你应该可以改变

$obj ['address_primary'] = '100 Main St';

到

$obj->address_primary = '100 Main St';

您还必须更改

echo 'City, State, Zip :: ', $obj ['state'];

到

echo 'City, State, Zip :: ', $obj->state;

  funciton __construct（$ primaryAddress =“”）{
  this-＆gt; address_primary =（strlen（trim（$ primaryAddress））＆gt; 0）？
  $ primaryAddress：$ defaultAddress;
  }
