note 36646 added to function.fopen

When treating binary mode file in PHP, is it impossible to create and write binary mode file? I can see many examples how to read binary file like image, but It dosen't work write. for example <? $data = "I am a boy."; $length = strlen($data); $fp = fopen("./temp_binary.dat", "wb"); fwrite($fp,$data,$length); fclose($fp); ?> At above script, generated file mode is not binary, but text. ---- Manual Page -- http://www.php.net/manual/en/function.fopen.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36646 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36646&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36646&report=yes Search -- http://master.php.net/manage/user-notes.php
