File name too long while deleting image in Laravel - php

Question

I am working on a Laravel project, the code saves the image inside a folder created with the title coming from a post. The problem is that while adding post it does not gives a warning saying filename too long but while deleting the post it says filename too long in demo.php/uploads/filename.php.
Is it really because of long folder name or something else?
The following code is called for deleting the folder while deleting a post.
function rmdir_recursive($dir) {
if (is_array($dir) || is_object($dir))
{
foreach(scandir($dir) as $file) {
if ('.' === $file || '..' === $file) continue;
if (is_dir("$dir/$file")) rmdir_recursive("$dir/$file");
else unlink("$dir/$file");
}
}
if (is_string($dir)) {
rmdir($dir);
}
}
Following the function to add post:
function create()
{
if($_SERVER['REQUEST_METHOD']=="POST")
{
$pid = rand(1000,9000);
$title = $_POST['title'];
$descpt = $_POST['description'];
$push = isset($_POST['send_push']) ? $_POST['send_push'] : "";
$feature_image = array();
$fy = $_POST['fy'];
if(empty($title) || empty($descpt) || empty($fy))
{
array_push($this->errors, MEND_FIELD_ERROR);
return;
}
if(!empty($_FILES['feature_image']['name'][0]))
{
$image = $_FILES['feature_image'];
$allowed_ext = array('jpeg','jpg','png','pdf','docx');
$allowed_size = 20000000;
foreach($image['name'] as $pos=>$image_name)
{
$dir = "./cdn/uploads/notice/".$title;
$tmp = $image['tmp_name'][$pos];
$img_size = $image['size'][$pos];
$img_error = $image['error'][$pos];
$img_ext = explode('.', $image_name);
$img_name = $img_ext[0];
$img_ext = strtolower(end($img_ext));
if(in_array($img_ext, $allowed_ext))
{
if($img_size <= $allowed_size)
{
if(!file_exists($dir))
{
mkdir($dir);
}
$image_new_name = $img_name.'$$'.uniqid('', true).'.'.$img_ext;
$upload_destination = $dir.'/'.$image_new_name;
if(move_uploaded_file($tmp, $upload_destination))
{
array_push($feature_image, $image_new_name);
}
else
{
array_push($this->errors, $img_error);
return;
}
}
}
else
{
array_push($this->errors, $img_ext.' is not an allowed file extension.');
return;
}
}
}
$s_feature_image = json_encode($feature_image, JSON_UNESCAPED_UNICODE);
$statement = $this->db->prepare("INSERT INTO `notice` (`pid`,`title`,`descpt`,`date`,`photo`,`fy`)
VALUES (?,?,?,?,?,?)");
if($statement->execute([$pid,$title,$descpt,DAT, $s_feature_image, $fy]))
{
if($push == "checked")
{
$descpt = strip_tags($descpt);
$tek = array("message"=>$descpt,"title"=>$title);
$tokens = $this->getTokens();
$this->push_notification($tokens,$tek);
}
ExitThis::send_to(URL.'notice?id='.$pid);
}
else
{
array_push($this->errors, DATABASE_ERROR);
return;
}
}
}
Note: The title will be Nepali character.

I don't know this was right but deleting folder if that is not string help me. I did following changes in my code:
function rmdir_recursive($dir) {
if (is_array($dir) || is_object($dir))
{
foreach(scandir($dir) as $file) {
if ('.' === $file || '..' === $file) continue;
if (is_dir("$dir/$file")) rmdir_recursive("$dir/$file");
else unlink("$dir/$file");
}
}
if(!is_string($dir)){
rmdir($dir);
}
}
