问题:

Why cant I use unlink() in Symfony?

I have tried this:

unlink(/Applications/XAMPP/xamppfiles/htdocs/symfonydev/web/account_assets/data/suppliers/file.txt)

I keep getting the same reponse: Warning: unlink(/Applications/XAMPP/xamppfiles/htdocs/symfonydev/web/account_assets/data/suppliers/wordpress.txt): Permission denied in...

What Do I need to do???

I have set the permissions to 777 on this file.

Note that you can use the remove function of the filesystem component. If you don't want to use the filesystem component, that's fine, you can use unlink(), there is a great example in this remove function of the doc:

public function removeUpload()
{
    if (isset($this->file)) {
        unlink($this->file);
    }
}

Now, the main problem is that you don't have permission to delete this file. You'd have to configure the directory like this in your virtual host:

<VirtualHost *:80>
    DocumentRoot "/Applications/XAMPP/xamppfiles/htdocs/symfonydev/web/"
    ServerName yoursite.dev
    <Directory "/Applications/XAMPP/xamppfiles/htdocs/symfonydev/web/account_assets/data/">
    AllowOverride None
    Allow from All
    </Directory>
</VirtualHost>

It was a permissions issue on main directory that contained the files. Once I changed the owner and permissions, all worked well. The filesystem component works awesome!
