#3515 [Opn]: fread() just read a few bytes

ID: 3515 Updated by: jaenecke@php.net Reported By: bjarne.ingelsson@enator.se Status: Open Bug Type: Documentation problem Operating System: WinNT4 SP6 PHP Version: 4 Assigned To: hholzgra New Comment: As explained in the documentation the mode for fopen() should contain a 'b' when accessing binary files on windows systems Previous Comments: ------------------------------------------------------------------------ [2002-10-01 15:06:55] hholzgra@php.net documentation should tell that fread may return early due to signal or other cause of interrupt, should give example using feof() ... ------------------------------------------------------------------------ [2000-02-17 09:15:02] bjarne.ingelsson@enator.se // PHP4b3 problem! // This version is not available in the dropdown... fread() doesn't return the correct number of bytes in Win32 environment. For some reason it just reads the first 33 bytes (in my example, depends on the file to be read). $sourcefile = "./aniclick.gif"; $fd = fopen($sourcefile, "r"); $contents = fread($fd, filesize($sourcefile)); $encoded = chunk_split(base64_encode($contents)); fclose($fd); echo "FileSize: ". filesize($sourcefile)."<BR> Read: ".strlen($contents). "<BR> Encoded: ".strlen($encoded). "<BR> Ratio: ". number_format((strlen($encoded) / strlen($contents)), 2). "<BR>"; The code above give the following result: FileSize: 19910 Read: 33 Encoded: 46 Ratio: 1.39 /Bjarne ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=3515&edit=1
