move_uploaded_file上传功能在 AWS EC2 实例中失败，并显示消息"failed to open stream: Permission denied"

我有一个最简单的php页面，用户只能上传MS Word或pdf文件。函数"move_uploaded_file"根本不起作用。我已经检查了 php.ini 中的限制，检查了目标文件夹中的文件和文件夹权限，所有内容都经过谷歌搜索和验证，包括查看 SELinux 是否有任何问题，但它只是拒绝上传，也没有看到任何错误。现在感到沮丧，没有与EC2实例相关的回复在线提及该解决方案。请求专家提供帮助并了解下面介绍的代码中出了什么问题

我的是一个 T2 大型实例，带有 PHP 7.2.11、Apache/2.4.37(红帽企业 Linux(、mysqld 8.0.17，仍然不明白问题是什么，也没有错误记录错误.log

<?php
include 'includes/UploadException.php';
define ('SITE_ROOT', realpath(dirname(__FILE__)));
echo "Current User:".get_current_user()."<br />";
if ($_POST['hdnOp'] == "A"){
$file = $_FILES['resume'];
$filename = $_FILES['resume']['name'];
$fileTmpName = $_FILES['resume']['tmp_name'];
$filesize = $_FILES['resume']['size'];
$fileerror = $FILES['resume']['error'];
$filetype = $_FILES['resume']['type'];

$newfilename = $random.$filename;
$uploadpath = "/BMT/UserProfiles/".$newfilename;

move_uploaded_file($fileTmpName,$uploadpath);

我应该能够在/BMT/UserProfiles/文件夹中看到该文件

[root@ip-XXX-XX-XX-XXX bmt]# ls -al /BMT/UserProfiles/
total 4
drw-r--r--. 2 apache apache  24 Oct 16 12:17 .
drw-r--r--. 3 apache apache  26 Oct 16 12:05 ..

ADyson 终于设法解决了这个问题......

chcon -R --type httpd_sys_rw_content_t /BMT/UserProfiles/

然后停止并启动httpd服务怀疑是否在某个地方 SELinux 负责......在此之后，现在它工作正常。感谢您的所有帮助和建议，真的帮助我从不同的角度进行调试
