PHP，使用fgets跳过文本文件的第一行和最后一行

Question

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.

Answer 1

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);
}
