PHP, skip first and last line of a text file using fgets

I'm trying to figure out how to skip the first and last line of a text file when I'm reading it while using fgets(). The first line could be solved with an if(!$firstLine), but I'm not sure how to ignore the last line or if my solution for ignoring the first line is the best choice.

You might want to try exploding the file contents. It will help you alot! After that you will label it.

fgets($file); //Ignore the first line
$line = fgets($file);
$next = fgets($file); 
while ($next !== false) { //check the line after the one you will process next.  
                //This way, when $next is false, then you still have one line left you could process, the last line.
    //Do Stuff
    $line = $next;
    $next = fgets($file);
}

try this 

 $str= file_get_contents("file.txt");
 $arr = preg_split ("\n",$str);
 $n = count($arr);

$n is a number of lines

$str="";
for($i=0;$i<$n;$i++){
   if($i>0 && $i<($n-1)){ $str.=$arr[$i]}
   }
    /**Str without line 1 and final line */

$lines = file('http://www.example.com/');//or local file

unset($lines[0]);
unset($lines[count($lines)-1)]);
$new_file = implode('', $lines); //may want to use line break "\n" for the join

Unfortunately, file() will open file into "serial" stream (not sure if serial is right word), it means that you must read full file before detecting his end
