我正在尝试使用下面列出的php代码读取json文件，但我无法将这些值分配给本地变量。
谁能帮我解释一下我做错了什么?
<?php
$file = "http://localsurch.com/deals2.txt";
$response = json_decode(file_get_contents($file), true);
//print_r($response);
foreach ($response as $mydeal)
{
$category = $mydeal->category->name;
$title = $mydeal->websiteTitle;
$finePrint = $mydeal->finePrint;
$imageURL = $mydeal->imageURL;
$merchant = $mydeal->merchant->displayName;
$streetaddress1 = $mydeal->redemptionLocations->addressStreet1;
}
?>

你告诉json_decode()给你一个数组，但你试着像访问对象一样访问它的值。要么返回一个对象…
$response = json_decode(file_get_contents($file));
…或者使用数组语法访问这些值:
foreach ($response as $mydeal)
{
$category = $mydeal['category']['name'];
$title = $mydeal['websiteTitle'];
$finePrint = $mydeal['finePrint'];
$imageURL = $mydeal['imageURL'];
$merchant = $mydeal->merchant['displayName'];
$streetaddress1 = $mydeal['redemptionLocations']['addressStreet1'];
}
