Issue using strpos with an array variable

[telman28]

I am not sure why this is happening, but any help would be greatly appreciated. I am really a novice, but I cannot figure out why the code $str_begin = strpos($s, $parameters[$worker]); is not working. What I am trying to do is to go through a file, pick out the $parameters variable with the additional information then store it in the array $parametervalue[$worker]. When I run the code I cannot get $str_begin to return anything . Please help

 

  <?php
   $handle = fopen("filename", "r");
  $parametervalue = array();

                       $parameters = array(
                                        'scannerId', 
                                        'hour', 
                                        'minute', 
                                        'second', 
                                        'millisec');
                        
                        while (! feof($handle))
                        {
                       $worker = 0;
                       while ($worker < count($parameters)) {

                            $s = rtrim(fgets($handle),"\r\n");
                            $findme = $parameters[$worker];
                            
                            if (strpos($s,$parameters[$worker]) !== FALSE)
                            {
                                $str_begin = strpos($s, $parameters[$worker]);
                                $str_end = strpos($s,",");
                                $str_len = $str_end - $str_begin;
                                $parametervalue[$worker] = substr($s,$str_begin,$str_len);
                            } else {
                                $parametervalue[$worker] = "";
                            }
                        $worker++;
                       }
                    }
   ?>

You do understand that for every worker you try to read a new line from the file? It's not that you're reading a file and then checking it for all the workers?

[telman28]

Yes, That is what I want to do. I want to take a line and then look for all of the "workers" in that line. The reason that I am doing it that way is because the files are tens of thousands of lines long and creates problems. Any idea on what is wrong though?

Ok, so I figured out what I was doing wrong. I guess as with a lot of this stuff I was making a dumb mistake. I had the $s variable assignment in the loop so it was changing all the time. That is what was throwing off the logic in the loop.
