Permission denied for subfolder

question
I'm trying to write a file in a specific folder but it's giving me permission returned .
So I verified the permissions and everything seemed fine. Since this is in a development environment, I decided to change the permissions on the "root" folder that writes all files to "Everyone can do anything." I tried replacing all permissions below. I'm trying to remove inherited permissions. Nothing can be done.
Then I try to write a file in the "root" folder. It worked. On subfolders it worked. on sub-subfolders. efficient. There is a point in the subfolder chain where it doesn't work, but before the actual subfolder.
This is the path hierarchy at the time of the crash.
$f = new \wee\common\IO\File();
$f->write("DRIVE:/BASE_PATH/files/-/00.jpg", "hello"); // WORKS
$f->write("DRIVE:/BASE_PATH/files/-/mod/00.jpg", "hello"); // WORKS
$f->write("DRIVE:/BASE_PATH/files/-/mod/com.ci.company/00.jpg", "hello"); // WORKS
$pathLength = strlen("DRIVE:/BASE_PATH/files/-/mod/com.ci.company/site/00.jpg"); // Real path length is 85
$f->write("DRIVE:/BASE_PATH/files/-/mod/com.ci.company/site/00.jpg", "hello"); // FAILS
$f->write("DRIVE:/BASE_PATH/files/-/mod/com.ci.company/site/WorkersManager/00.jpg", "hello");
$f->write("DRIVE:/BASE_PATH/files/-/mod/com.ci.company/site/WorkersManager/workers/00.jpg", "hello");
Class \wee\common\IO\File was created by me, but can be used in many other places.
The exact error message I received was:
fopen(DRIVE:/BASE_PATH/files/-/mod/com.ci.company/site/00.jpg): Unable to open stream: Permission denied
100% clear: the "root" folder is DRIVE:/BASE_PATH/files/
Edit#1
Here is the implementation of the write method of the File class.
public function write($fileName, $data, $lock = false) {
$this->_write($fileName, $data, $lock);
}
private function _write($fileName, $data, $lock = false, $openMode = 'w') {
if ($data === null)
$data = "";
$fh = fopen($fileName, $openMode) or die("can't open file"); // FAILS HERE
if ($lock) {
flock($fh, LOCK_EX);
}
fwrite($fh, (is_array($data) ? join("\n", $data) : $data));
if ($lock) {
fflush($fh);
flock($fh, LOCK_UN);
}
fclose($fh);
}
