The file function does not need to use php to read the last line of a large file. The file function does not need to use php to read the last line of a large file.

You can use fseek to specify the last position and then read it forward.
For example, fseek ($ fp,-1, SEEK_END); then the first line of the last line is reached.

For example, I want to go to the last line. how can I write the specific code? give a demo. thank you!
$ Fn = 'Your text filename '; $ fp = fopen ($ fn, 'r'); fseek ($ fp,-1, SEEK_END); $ s = ''; while ($ c = fgetc ($ fp ))! = False) {if ($ c = "\ n" & $ s) break; $ s = $ c. $ s; fseek ($ fp,-2, SEEK_CUR);} fclose ($ fp); echo $ s;
If the file is not huge, it is convenient to read the file.
$fp = fopen($fn, 'r');while($buf = fgets($fp)) $res = $buf;fclose($fp);echo $res;
