What is PHP for C# ReadBytes(stream langth)? -

What is PHP for C # (as we open some local files on the server (instead of OpenFileDialog)

Private const int HEADER_LENGTH = 13; stream = file.OpenRed (OpenFileDialog.filname); Header = ReadBase (stream, HEADER_LENGTH);

It will be able to do this in PHP as the next step

  Private cost byte sign 1 = 0x46; Private cost byte signature 2 = 0x4C; Private cost byte signature 3 = 0x56; if ((Sign = = Header [0]) | (Signature 2! = Header [1]) || (Signature 3! = Header [2]) Throw new invalid data exception ("Not valid FLV file ! ");

Hmm, I think you find something like this < / P> $ code = $ handle = fopen (FILE, 'r'); ) ... ...}

Definitely y can create constants for this signature, but like this:

  define ('SIG1', chr (0x46));  

Then you can use them as normal: $ head [0] == SIG1 etc. When defining a constant constant, for both fixed name and value.
