I think this can be achieved by checking whether the string is a valid url using a regex. This regex is got from another SO post: “\\b(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]” You first check whether url is a valid url using this regex.

The if-statements you use are quite straightforward, the only possibility is that $_SESSION[“Member_type”] always is the value “S”. This means that the ‘problem’ is something else. You can easily verify this yourself. Right before you do the if-statement, you place print_r($_SESSION). If you do that, you’ll see the values in the session array. It could … Read more

You can use the constructor to specify the filename: ifstream inputFile(“data.txt”); See the details for std::basic_ifstream (constructor). explicit basic_ifstream( const char* filename, std::ios_base::openmode mode = ios_base::in ); First, performs the same steps as the default constructor, then associates the stream with a file by calling rdbuf()->open(filename, mode | std::ios_base::in) (see std::basic_filebuf::open for the details on … Read more
You must keep in mind: if your web-server disallows to scan a directory then you couldn’t get file names.
