(Streams stuff broke this) ------------------------------------------------------------------------ [2005-04-24 16:04:54] matteo at beccati dot com Description: ------------ In recent PHP versions, fread only reads 8192 bytes from a file generated with tmpfile(). I've already seen bug reports #29023 and #30936 which seem strongly related to this issue. From what I can see, fread on local files isn't limited to the PHP chunk size of 8192, while a fread on a tmpfile acts like it was i.e. a network stream, breaking backwards compatibility. I found out this issue investigating a recently reported bug for phpAdsNew, which uses this function to deal with remote ftp-stored files. IMVHO this can be considered a bug in in the tmpfile() implementation. If you don't agree, well... I suggest to mark it as a documentation bug, because I couldn't find nothing related to the 8192 bytes limit in the manual. Versions/OS tested and affected: PHP 4.3.10 Linux PHP 4.3.11 FreeBSD and Windows PHP 5.0.4 Windows Versions/OS tested and unaffected: PHP 4.3.4 Windows Reproduce code: --------------- <?php $fp = tmpfile(); // This would give the correct result // $fp = fopen('/tmp/test.dat', 'w+'); fwrite($fp, str_repeat('0', 100000)); $size = ftell($fp); rewind($fp); $buf = fread($fp, $size); echo "Bytes written: ".$size."\n"; echo "Bytes read: ".strlen($buf)."\n"; fclose($fp); ?> Expected result: ---------------- Bytes written: 100000 Bytes read: 100000 Actual result: -------------- Bytes written: 100000 Bytes read: 8192 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32810&edit=1
