PHP: Create folder using fopen

fopen cannot be used to create directories. This is because the fopen function does not create or open folders, it only works with files.

Before using the fopen function, you should first check whether is_dir exists. If it does not exist, use the mkdir function to create it -

$filename = '/path/to /file.txt';
$dirname = dirname($filename);
if (!is_dir($dirname)) {
   mkdir($dirname, 0755, true);
}

The above code creates a file named "filename" path. Use the "dirname" function to get the directory of "filename". Next, use the "is_dir" function to check if the directory exists. If the directory already exists, no action is taken. On the other hand, if the directory does not exist, then the "mkdir" function is used to create the directory by passing specific access permissions.
