PHP 中 Wget 的问题
如果我在 shell 中运行命令，它会下载它，shell 没有错误
，但 PHP 页面总是会转到 if 语句，
我尝试了 shell_exec ，结果是相同的，
我真的想这样做Wget
但是，如果这是不可能的，并且您的解决方案是 cURL，请告诉它更多详细信息，然后我可以找到如何编码
$flag=system('wget -P /srv/www/htdocs/didebansnort/Downloads http://www.snort.org/reg-rules/snortrules-snapshot-2900.tar.gz/myoinkcodethatmustbesecret
');
if(!$flag)
{
echo '<script>alert("please try again!")</script>';
}
如果问题与权限有关，我该如何修复它？
建议已开放 但我必须从命令行下载 如果你觉得可以的话！
这是网站
https://www.snort.org/snort-rules/#rules
例如，右键单击 snortrules-snapshot-2904.tar.gz 我可以拥有它 现在我认为通过 fopen 是不可能的，我怎样才能访问它？ 我认为解决方案“只是”通过 PHP 命令行下载 我不知道！
谢谢
if I run the command in shell it will download it,No error by shell
but by PHP page always it goes to if statement
I tried shell_exec and the result is the same
I really want to do it just by Wget
But if this is impossible and your solution is cURL please tell it in more details then I can find out how to code it
$flag=system('wget -P /srv/www/htdocs/didebansnort/Downloads http://www.snort.org/reg-rules/snortrules-snapshot-2900.tar.gz/myoinkcodethatmustbesecret
');
if(!$flag)
{
echo '<script>alert("please try again!")</script>';
}
If the problem is about permissions How can I fix it?
suggestion was fopen
but I have to download from command line
If you think it is possible!
here is the site
https://www.snort.org/snort-rules/#rules
well for example by rightclick on snortrules-snapshot-2904.tar.gz
I can have it
now I think it is impossible by fopen how can I make access to it?
I think solution is "just" download via command line in PHP
I don't know!
Thanks

您确定您的 PHP 配置允许您执行 system() 并且允许您以 root 身份运行它吗？
Are you sure your PHP config allows you to execute system() and that it allows you to run it as root?
sudo 以哪个用户身份运行？该用户是否可以无密码访问 root（如果是，为什么！）您确实需要避免 sudo 位，它很可能会失败。只需确保用户 PHP 运行时可以写入 /srv/www/htdocs/didebansnort/Downloads（了解其中的风险）并在不使用 sudo 的情况下运行 wget 即可。
更好的是，为什么不使用 PHP 的内置方法之一来获取远程文件呢？ （
fopen？）Which user is the sudo running as? Does that user have passwordless access to root (if so, why!) You really need to avoid the
sudobit, it's very probably failing. Just make sure the user PHP runs as can write to /srv/www/htdocs/didebansnort/Downloads (understanding the risks there-of) and run the wget without thesudo.Even better, why not use one of the built in methods of PHP to get a remote file? (
fopen?)
