note 89027 added to function.ftell

RE: append-only streams My testing shows that ftell always reports 0 when you first open a file regardless of the mode it was opened in. If open a file in append mode (a) and you want ftell to report the actual position in the file instead of the position relative to where you entered you can use fseek <?php // create a test file with 100 bytes in it $file = 'temp.log'; $fp = fopen($file, 'w'); fwrite($fp, str_repeat('+', 100)); fclose($fp); // append mode to show fseek $fp = fopen($file, 'a'); echo ftell($fp), PHP_EOL; // reports 0 even though you are at char 100 fseek($fp, 0, SEEK_END); // seek to end (does nothing on append streams) echo ftell($fp), PHP_EOL; // reports 100 fwrite($fp, str_repeat('+', 100)); echo ftell($fp), PHP_EOL; // reports 200 ?> ---- Server IP: 64.71.164.2 Probable Submitter: 64.135.71.194 ---- Manual Page -- http://www.php.net/manual/en/function.ftell.php Edit -- https://master.php.net/note/edit/89027 Del: integrated -- https://master.php.net/note/delete/89027/integrated Del: useless -- https://master.php.net/note/delete/89027/useless Del: bad code -- https://master.php.net/note/delete/89027/bad+code Del: spam -- https://master.php.net/note/delete/89027/spam Del: non-english -- https://master.php.net/note/delete/89027/non-english Del: in docs -- https://master.php.net/note/delete/89027/in+docs Del: other reasons-- https://master.php.net/note/delete/89027 Reject -- https://master.php.net/note/reject/89027 Search -- https://master.php.net/manage/user-notes.php
