讀取檔案的最後幾行

$n = 20 //要讀的行數 $fileName = "name"; //要讀的檔案 $fp = fopen( $fileName, 'r' ); // 開啟檔案 fseek($fp,0,SEEK_END); $c = ftell($fp); $countline = 0; while ($c > 0 && $countline < $n ) { //從最後往前找第$n個\n   if ( fgetc( $fp ) == chr(10) ) $countline += 1;   $c -= 1;   fseek($fp,$c) ; } $data_array=explode(chr(10),fread($fp, filesize($fileName))); fclose($fp); $data_array 為讀取結果
