我想访问,这个数组
(结果中的release_dates内的认证)
"results": [
{
"iso_3166_1": "IN",
"release_dates": [
{
"certification": "U",
"note": "",
}
]
}
]
我正在使用此代码:
if (isset($response4["results"]) && is_array($response4["results"]))
{
foreach ($response4["results"] as $genreObject)
{
$release_dates_iso_3166_1 = $genreObject["iso_3166_1"];
$release_dates_certification = $genreObject["release_dates"]["certification"];
$stmt->execute();
}
}
但此代码只能访问iso_3166_!
而不是certification
错误:注意:未定义索引:认证
答案 0 :(得分:2)
因为if (isset($response4["results"]) && is_array($response4["results"]))
{
foreach ($response4["results"] as $genreObject)
{
$release_dates_iso_3166_1 = $genreObject["iso_3166_1"];
$release_dates_certification = $genreObject["release_dates"][0]["certification"];
$stmt->execute();
}
}
是数组,您必须使用此数组的第一个元素:
<html><head><meta charset="utf-8"><title>Blog</title><link rel="stylesheet" href="styles.css"></head><body><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"/><script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"/><script src="main2.js"/><div class="container"> <form id="contact" action="" method="post"><h3>Colorlib Contact Form</h3><h4>Contact us for custom quote</h4><fieldset><input id="name" placeholder="Name" type="text" tabindex="1" ></fieldset><fieldset><input id="author" placeholder="Author" type="text" tabindex="2" ></fieldset><fieldset><textarea id="content" placeholder="Content...." tabindex="5" /></fieldset><fieldset> <button id="nextButton"> Next </button> </fieldset><p class="copyright">Designed by <a href="https://colorlib.com" target="_blank" title="Colorlib">Colorlib</a></p></form></div> </body></html>

release_dates
键包含数组,而不是对象。所以你应该迭代或访问密钥。
if (isset($response4["results"]) && is_array($response4["results"])) {
foreach ($response4["results"] as $genreObject) {
$release_dates_iso_3166_1 = $genreObject["iso_3166_1"];
$release_dates_certification = null;
foreach ($genreObject["release_dates"] as $release_dates_elements) {
$release_dates_certification = $release_dates_elements["certification"];
}
}
}
