这是我的PHP脚本
<?php
require_once 'GoogleMovieShowtimes.php';
//Requests www.google.com/movies?near=washington
$test = new GoogleMovieShowtimes('washington');
ob_start();
var_dump($test->parse());
$save = ob_get_contents();
ob_end_clean();
$save=json_encode($save);
$saveJSON=json_decode($save);
print_r($saveJSON);
?>
我得到的输出就是这个

但是现在如果我做了
print_r($saveJSON["theater"]);
我得到的只是'a'......没有别的，是不是应该打印剧院阵列？ 什么出错？
如果我不做json_encode（）和json_decode并且只是echo $ save我得到相同的输出，那么我如何迭代这些数组呢？
答案 0 :(得分：5)
print_r($saveJSON["theater"])，需要print_r($saveJSON[0]["theater"]);
因为看起来saveJSON是一个包含1个元素的数组，而后者又是一个关联数组。
同时更改您的JSON解码以返回数组而不是对象。
改变这个：
$saveJSON=json_decode($save);
到
$saveJSON=json_decode($save,true); // to have saveJSON as an array, not object
