#43522 [NEW]: stream_get_line eats additional characters

From: tylera at iproduction dot com Operating system: Gentoo Linux, Win32, Solaris PHP version: 5.2.5 PHP Bug Type: Streams related Bug description: stream_get_line eats additional characters Description: ------------ Calling stream_get_line may eat additional characters when reading a long line. If the delimiter is not encountered, a number of additional characters are removed from the stream and are not returned with the next call to stream_get_line. For some unknown reason, adding \r to the delimiter makes it work just fine. Reproduce code: --------------- <?PHP // 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ $fp = fopen('test.php', 'r'); // Open myself DoTest($fp, 'ZZZ'); // Removes 3 characters DoTest($fp, "\r"); // Doesn't break with \r for some reason function DoTest($fp, $delim) { echo "Delim: " . urlencode($delim) . "\n"; rewind($fp); echo " " . stream_get_line($fp, 10, $delim) . "\n"; echo " " . stream_get_line($fp, 10, $delim) . "\n"; } Expected result: ---------------- Delim: ZZZ <?PHP // 1 234567890A Delim: %0D <?PHP // 1 234567890A Actual result: -------------- Delim: ZZZ <?PHP // 1 567890ABCD Delim: %0D <?PHP // 1 234567890A -- Edit bug report at http://bugs.php.net/?id=43522&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43522&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43522&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43522&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43522&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43522&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43522&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43522&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43522&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43522&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43522&r=support Expected behavior: http://bugs.php.net/fix.php?id=43522&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43522&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43522&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43522&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43522&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43522&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43522&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43522&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43522&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43522&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43522&r=mysqlcfg
