Nice ;) (y)

L8: mkdir ($dir); is giving error when there is a existing directory already there in place. I think if we do

if ( ! is_dir($dir) ) {
  mkdir( $dir );
}

it won't show any error then.

যদি অ্যাভাডা টেমপ্লেটটা ধরে নিই, এবং প্রথম ফাইলটার পাথ যদি https://0.s3.envato.com/files/62386858/Screenshots/01_home_v1.__thumbnail.jpg হয়, তাহলে usage কীরকম হবে?
১. php envato-screenshots-downloader.php C:\Screenshots\ https://0.s3.envato.com/files/62386858/Screenshots/01_home_v1.__thumbnail.jpg
নাকি
২. php envato-screenshots-downloader.php C:\Screenshots\ https://0.s3.envato.com/files/62386858/Screenshots/
আমি Windows 7-এর PowerShell ব্যবহার করে চেষ্টা করছি, এবং উভয় ক্ষেত্রেই ফলাফল শূণ্য পেয়েছি। :(

No working for me !
Can you explain how to use ?
Thank you.
