Hello, I am trying to find out if a string is in a line being read from a
file.  I should use strstr for this I am pretty sure.
I want to do something like this:  switch(strstr($line, case argument))  but
I don't know if it is possible.  For example, I am looking for Zip in a line
but it will not find it using the code below.  Any suggestions?  I know I am
being as clear as mud on this :)

$fd = fopen("mls1.txt", "r");
while(!feof($fd))
  {
  $line=fgets($fd, 4096);
  switch($line)
    {
    case "Zip":
      echo "found zip";
      //$line2=fgets($fd,4096);
      $zip=$line;
      break;

    case "Remarks":
      //$line2=fgets($fd,4096);
      $neighborhood=$line;
      break;

    case "Taxes":
      //$line2=fgets($fd,4096);
      $address=$line;
      break;

    }

  }
fclose($fd);
