PHP - fopen: failed to open stream: Permission denied - php

Question

I'm new to PHP. I planned to create folder, sub folder, into that file depends on user Input.
Folder and sub folders has been created successfully.
Finally I try to create a file its showing bellow error.
fopen(upload/localhost/hrms): failed to open stream: Permission denied
in C:\xampp\htdocs\ssspider\index.php on line 205
My code is:
$dir = "http://localhost:8080/hrms/index.php";
//make directory
$directoryForServer = "upload";
$directoryForClient = $directoryForServer."/".$host."";
mkdir($directoryForClient);
$splitePath = explode("/", $folderPath);
$folderPath1 = $directoryForClient;
for($x = 1; $x <= (count($splitePath)-1) ; $x++)
{
$folderPath1 = $folderPath1."/".$splitePath[$x];
echo "<br>".$folderPath1." - successfully created<br>";
mkdir($folderPath1);
}
writefile($folderPath1);
function writefile($dir)
{
if( is_dir($dir)){
echo $dir;
$myFile = fopen($dir,"w");
if($myFile)
{
fwrite($myFile, $returned_content);
}
fclose($myFile);
}
}
Please help me to find out my problem?
Edit: Thanks. I got an error. In fopen I didn't mention file name . Now its working fine. Thanks

because you open a directory , fopen function just open file. your code is fill with error , just Refer to the following:
<?php
//make directory
$host = "aa"; //define $host variable
$directoryForServer = "upload";
$directoryForClient = $directoryForServer."/".$host."";
#mkdir($directoryForClient);
$splitePath = explode("/", $directoryForClient);
$folderPath1 = $directoryForClient;
for($x = 1; $x <= (count($splitePath)-1) ; $x++)
{
$folderPath1 = $folderPath1."/".$splitePath[$x];
echo "<br>".$folderPath1." - successfully created<br>2";
#mkdir($folderPath1);
}
writefile($folderPath1);
function writefile($dir)
{
if( is_dir($dir)){
echo $dir;
$myFile = fopen("upload/aa.txt","w");
if($myFile)
{
$returned_content = "hello world"; //define variable and his content before write to file.
fwrite($myFile, $returned_content);
}
fclose($myFile);
}
}
