我有一个PHP脚本A,它显示数据库中的数据。
我还有另一个脚本B,它获取脚本A的内容。但是我需要脚本A执行后的内容。但这不会发生。
//脚本A
enter code here
<?php
session_start();
if(!isset($_SESSION['username']))
{
print "You have not logged in";
header('Location: index.htm');
}
session_write_close();
?>

//脚本B
$ch = curl_init();
$url = "http://localhost/waves/viewresults.htm?id=".$id;
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, $url);
$data = curl_exec($ch);
curl_close($ch);
chdir("temp/file");
$myFile = "summary.htm";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $data);
fclose($fh);
文件summary.htm只有脚本A的代码,这意味着它没有执行nnd因此没有来自数据库的数据。
我做错了什么?
答案 0 :(得分:3)
所以我开始回答而没有阅读你的代码,但现在看到你正在使用JavaScript从脚本A输出数据而不是使用PHP。
为什么它不能工作:您使用客户端JavaScript在运行时动态创建表。这将在浏览器中正确呈现,但不会通过curl呈现。 libcurl不支持javascript。
建议的解决方案 我建议您修改getviewresults.php并按照this tutorial缓冲输出到文件,或者您也可以选择重写脚本A以使用服务器端脚本。
这是一个非常有趣的问题,谢谢你。
答案 1 :(得分:0)
尝试将“viewresults.htm”重命名为“viewresults.php”,以便将其解析为PHP(您可以使用mod_rewrite将viewresults.htm内部重定向到viewresults.php,以便您的网址不会更改)。
答案 2 :(得分:0)
打开您尝试在浏览器中显示的网址 - 即http://localhost/waves/viewresults.htm?id=X
(正确值为X
) - 并查看输出的内容。
如果您仍然在浏览器中看到PHP代码,那么您就知道该文件未被解析为PHP。默认情况下,最后只有.php
的文件名将以PHP格式执行。
另外,我认为脚本A中的代码无论如何都不会正确执行,因为会话变量不会被设置。
