I don't see what is wrong with this array read

    $handle = fopen("/etc/rpt.fifo", "r") or die("Unable to open file!");
       $buffer = trim(fgets($handle));                
       $ary = explode (",", $buffer);  
       $x = $ary[2];
       print $x;
       flush();   
       pclose($handle);

        

When I run it, it reports:

Notice:  Undefined offset: 2 on line 4

This is the line in /etc/rpt.fifo that is being read (there are 4 indices)

20210721153256,1100,TXKEY,89790

The error makes no sense to me but I'm no expert <g>
