The full cod in the loop is.

  $cnt = 0;
  while(!feof($fp))
  {
    // Get body
    $line_in = fgets($fp,4096);
    $cnt++;
    // looking for the other end of the marker found above
    if (substr($line_in,2,strlen($line_in)-5) != $marker )
    { 
      $body    = $body . $line_in;
      $hit[]   = preg_match ($ts, $line_in,$matches);
      $line[]  = $line_in;
      $char    = substr($line_in,0,1);
      $quote[] = preg_match ($qs, $char);
    }
    if (strpos($line_in, $marker) > 0 ) { 
      break; 
    }
  }

Later on in the code after the loop I do

                echo "printing array matches <br>";
                print_r ($matches);echo "<br>";
                
                echo "printing array hit <br>";
                print_r ($hit);
                
                echo "printing array quote <br>";
                print_r ($quote);

                echo "printing array lins <br>";
                print_r ($line);
                
                $lcnt = count($line);
                echo "cnt of line array is $lcnt <br>"; 

                $hcnt = count($hit);
                echo "cnt of hit array is $hcnt <br>"; 

                $qcnt = count($quote);
                echo "cnt of quote array is $qcnt <br>"; 
        
                $mcnt = count($matches);
                echo "cnt of matches array is $mcnt <br>"; 
                
the arrays $hit and $line and $quote all print data, and all the 

count($array) print a value except the $matches array and count are
empty.
