[PHP] something like a C "struct" or "union" in PHP?

[Arne Borkowski \(borko.net\)]

Hi Folks,

I want to do the following:


        $f = fopen($filename", "r");

        while( !feof($f) ) {
         $len=1;
         $RECSIZE=128

         while($n=1;$n<=$len;$n++)
          $data = fread($f, $RECSIZE);

         $rectype = $data[4];

         switch($rectype) {
                
                case "A": $numARec++;
                            $len=1;
                        
                                // do something with the
                                // contents of $data

                            break;

                case "C": $numCRec++;
                            $len=2; // at least!

                                // do something with the
                                // contents of $data

                            break;

                case "E": $numERec++;
                            $len=1;

                                // do something with the
                                // contents of $data

                            break;
         } /* switch */

         fclose($f);

        } /* while */

This snippet reads a data file in 128 bytes truncs
and needs to analyse the contents. As each 128 bytes
trunc has a certain structure (say: fields to access)
I would appreciate a thing like a C "struct" or so.

In C I could eaysly read the RECSIZE bytes into a
struct and access certain bytes via a "named" part
of it. Is there anything similar to this in PHP? I
couldn't find a "struct" or so in the manual. The
site's search engine said 41 hits for "struct" in
the Web Site content, but didn't show the matching
docs?! I need help on "struct" from you guys!

TIA

-Arne
