Answer 1

You need to allow

allow_url_fopen

in your php.ini config file. Some hosts disallow it for security.

Answer 2

Check the php.ini file and make sure similar is available as below

; Whether to allow the treatment of URLs (like http:// or ftp://) as files. ; http://php.net/allow-url-fopen allow_url_fopen = On

; Whether to allow include/require to open URLs (like http:// or ftp://) as files. ; http://php.net/allow-url-include allow_url_include = Off

Answer 3

A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.
