I have this code to upload my files, but i want them to upload with CHMOD 755, need some help, please.

Answer 1

Two options:

1. First upload file completely, then chmod it.
2. Create empty file, chmod it, then put your data into it.

Doing a chmod on a file is rather simple in PHP:

chmod("/directory/file", 0755);  

Just remember that you need to use octal and not decimal to get the correct value of mode; so prepend your "755" with a "0" as shown in the example above!

For your code, I would do it like this:

public function receive()
{
    ...

    chmod($this->path . $this->fileName, 0755); 
    return true;
}
