Previous Comments: ------------------------------------------------------------------------ [2002-08-20 08:58:44] dams@php.net Hi, on my PHP 4.1.2, fread() adds randomly a addslashes() when reading a binary file. Here is the code : <?php $fp=fopen($fichier,"r"); $attendu = filesize($fichier); $attachmentorig=fread($fp,$attendu); $lu = strlen($attachmentorig); print "awaited : $attendu<BR>\n"; print "read : $lu<BR>\n"; fclose($fp); ?> basically, it reads the file (I used any JPG picture as test), and then it happens sometimes (rather unusually) that the read size is about 10% bigger than the original file size. The increase in size is always the same, when it happens. With further testing, I finally managed to find that, if the returned string is bigger than the original file size, then applying stripslashes() will solve the trouble. I tested this also on 4.2.2 (macosx) and fresh 4.3.0-dev, and no trouble seems to be reproducable, so it may be a solved trouble. It may be a 4.1.2 specific trouble. I hope this post will help anyone facing this trouble, or point some real bug. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18984&edit=1
