#22682 [Com]: Proplems with fread(), ftell() and fseek() and CRLF newlines

ID: 22682 Comment by: frank at heuveltop dot nl Reported By: fbeyer at clickhand dot de Status: No Feedback Bug Type: Filesystem function related Operating System: Windows XP PHP Version: 4CVS-2003-04-28 (stable) New Comment: I run PHP as a Apache (2.0.48) module. I tried several methods but there is no way PHP will read "\r" from the file. The filepointer returned by ftell is getting out of sync. I do confirm all the symptoms that are stated above. Allthought I can build a workaround by counting lines and add the number of lines to ftell, I am worried about reading binary files like images by GD library. Previous Comments: ------------------------------------------------------------------------ [2003-11-28 15:32:18] alexey at ozerov dot de I still have a related bug on Windows XP using PHP 4.3.4. Sample: <? header("Content-type: text/plain"); ini_set("auto_detect_line_endings", true); // Doesn't matter $file=fopen(__FILE__,"rt"); // "t" doesn't matter too $linenumber=0; while ($file && $line=fgets($file, 65536)) { echo ("$linenumber: ".$line."\n"); fseek($file, ftell($file), SEEK_SET); $linenumber++; } fclose($file); ?> fseek() should not do anything but it _shifts_ the file pointer (as many bytes back as many "\r" are in the last read input) if I the __FILE__ has DOS encoded line breaks. As the result every line is followed by a blank line in the sample output. ------------------------------------------------------------------------ [2003-08-17 18:34:15] sniper@php.net No feedback was provided.
