I tried to improve and modify (mail at ulf-kosack dot de)'s function. Actually it is very fast, i.e. requires much less time than to get the last five, ten or whatever lines of a file using file() ore file_get_contents(). function read_file($file, $lines) { $handle = fopen($file, "r"); $linecounter = $lines; $pos = -2; $beginning = false; $text = array(); while ($linecounter > 0) { $t = " "; while ($t != "\n") { if(fseek($handle, $pos, SEEK_END) == -1) { $beginning = true; break; } $t = fgetc($handle); $pos --; } $linecounter --; if($beginning) rewind($handle); $text[$lines-$linecounter-1] = fgets($handle); if($beginning break; } fclose ($handle); return array_reverse($text); // array_reverse is optional: you can also just return the $text array which consists of the file's lines. } The good thing now is, that you don't get an error when your requesting more lines than the file contains. In this case the function will just return the whole file content. ---- Server IP: 194.153.94.10 Probable Submitter: 213.200.229.203 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.fseek.php Edit -- https://master.php.net/note/edit/69008 Del: integrated -- https://master.php.net/note/delete/69008/integrated Del: useless -- https://master.php.net/note/delete/69008/useless Del: bad code -- https://master.php.net/note/delete/69008/bad+code Del: spam -- https://master.php.net/note/delete/69008/spam Del: non-english -- https://master.php.net/note/delete/69008/non-english Del: in docs -- https://master.php.net/note/delete/69008/in+docs Del: other reasons-- https://master.php.net/note/delete/69008 Reject -- https://master.php.net/note/reject/69008 Search -- https://master.php.net/manage/user-notes.php
