Get and cache any Twitter profile image without the Twitter API.

get_twitter_profile_image

function get_twitter_profile_img($username, $size = '') {
    $api_call = 'https://twitter.com/users/'.$username.'.json';
    $results = json_decode(file_get_contents($api_call));
    $image_url = str_replace('_normal', $size, $results->profile_image_url);

    // Replace with your cache directory.
    $image_path = './cache/';
	
    // Get the name of the file.
    $exploded_image_url = explode("/",$image_url);
    $image_filename = end($exploded_image_url);
    $exploded_image_filename = explode(".",$image_filename);
    $extension = end($exploded_image_filename);
	
    // Make sure its an image.
    if($extension=="gif"||$extension=="jpg"||$extension=="jpeg"||$extension=="png"){
	
        // Get the remote image.
	$image_to_fetch = file_get_contents($image_url);
		
	// Save it.
	$local_image_file  = fopen($image_path.$image_filename, 'w+');
	chmod($image_path.$image_filename,0755);
	fwrite($local_image_file, $image_to_fetch);
	fclose($local_image_file);	
    }
	
    return $image_path.$image_filename;
}

That is indeed what I meant.
