move_uploaded_file gives “failed to open stream: Permission denied ” even with 777

Question

I get this error with Apache 2.4 and PHP 7 on CentOS.

I have folder structure like this:

var
  -- www
    -- html
      -- upload.php
      -- uploads
      -- images

And when I run move_uploaded_file( $tmpDir, '/var/www/html/uploads' ); - everything works flawlessly.

But the error comes when I try to change the destination directory to /var/www/html/images.

Warning: move_uploaded_file(/var/www/html/images/test.jpg): failed to open stream: Permission denied in /var/www/html/upload.php on line 14

Warning: move_uploaded_file(): Unable to move '/tmp/phps3D2Em' to '/var/www/html/images/test.jpg' in /var/www/html/upload.php on line 14

Both folders have the same 755 mode and same owner (apache). But somehow it gives me error when I want to upload in images folder.

I ran posix_getuid() from PHP and it gives me ID of the Apache user.

What could be the issue?

Edit:

Results of ls -lh /var/www/html:

drwxr-xr-x.  2  apache  root   88K Mar 13 12:36 uploads

Results of httpd -S:

Edit 2: I have this script set on /var/www/html/perms.php:

print posix_getuid();
$dirs = array_filter(glob('*'), 'is_dir');
foreach( $dirs as $dir ) {
  if ( is_writable($dir) ) print "{$dir} is writable.<br>";
  else print "{$dir} is not writable.";
}

and the output:

48
images is not writable. Permissions may have to be adjusted.
uploads is writable.
