note 47803 added to function.is-writable

One snag I've found is that on Windows, CDROM drives are not 'read only' meaning that if this function is only passed the drive letter for a CD drive, it will return true even though fopen will fail and writing is not possible (does not matter if it is a burner or not). As a workaround for a script of mine: function read_only ($path) { if (preg_match ("/^([A-Za-z]:)\\\\?/", $path, $match)) { echo $match[1]; if ($writable = @fopen ($match[1] . ".writetest", 'w')) { fclose ($writable); unlink ($match[1] . ".writetest"); } } else { $writable = is_writable ($path); } return !$writable; } ---- Manual Page -- http://www.php.net/manual/en/function.is-writable.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47803 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47803&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47803&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47803&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47803&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47803&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47803&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47803&report=yes Search -- http://master.php.net/manage/user-notes.php
