我需要检索来自PHP文件的URL,其中包含mysql变量。不幸的是他们没有被正确归还。
以下是我链接的html文件:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="index" href="toc1.php" type="application/json">
</head>
我的toc1.php是文件:
<?php
$username = $_GET['username'];
$papername = $_GET['papername'];
header('Content-Type: application/json');
$username = json_encode($username);
$papername = json_encode($papername);
?>
[{
"url": <?php echo '<a href="http://www.yoozpaper.com/cover.php?
username=' . $username . '&papername=' . $papername . '" ></a>';?>
},
{
"url": <?php echo '<a href="http://www.yoozpaper.com/tocindex.php?
username=' . $username . '&papername=' . $papername . '" ></a>';?>
},]

如何删除json_encode? p>
json_encode函数使json对象形成数组:
$json = array();
$json['something'] = "something else";
$json['and_again'] = "more things";
然后json_encode($json)
返回:
{
"something": "something",
"and_again": "things"
}
所以json编码一个字符串:
$username = "John Doe";
echo json_encode($username);
会导致"John Doe"
或错误

我建议遵循:
$list = array();
$objItem = new stdClass();
$objItem->url = '<a href="…?username=' . $username . '&papername=' . $papername . '"></a>';
$list[] = $objItem;
// add more items
最后,输出:
echo json_encode($list);

header()
调用必须是文件的第一行,请参阅manual。所以把它改成
<?php
header('Content-Type: application/json');
$username = $_GET['username'];
$papername = $_GET['papername'];
$username = json_encode($username);
$papername = json_encode($papername);
?>
GET
变量应该来自哪里?您可能想要将链接更改为
<link rel="index" href="toc1.php?username=foo&papername=bar" type="application/json">

您的Json {"some":"some"}
此处href =''
<a href='{"some":"some"}'>Some</a>
不是这个
<a href="{"some":"some"}">Some</a>
