Sorry for not fully clear description. Thank you for interest to this problem. gmc(at)sonologic(dot)nl understood my description and put code for reproducing this problem. Thanks also to him. Problem occurred when we updated PHP from 5.2.10 to 5.2.11 on our production. On PHP 5.2.10 problem code on the same server worked properly. We tested problem code on the same server using PHP version 5.2.8 and also code worked properly. Now we rewrote our code for downloading big HTTP files without using fgets(using socket_create, socket_bind, socket_connect, socket_select, socket_write, socket_read and socket_close). It works fine on PHP 5.2.8 and 5.2.11. And it working fine in production on PHP 5.2.11. So this is bug, not a configuration issue. -- With best regards, Andrei. ------------------------------------------------------------------------ [2009-10-12 11:51:32] gmc at sonologic dot nl I'm experiencing the same problem on: FreeBSD 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0: Tue Oct 14 11:55:05 CEST 2008 r...@postel:/usr/obj/usr/src/sys/GENERIC i386 The problem is that feof($fp) returns TRUE, even though the end of the remote file has not been reached. The below script reproduces the problem. I'm sorry it depends on an external resource, that's just the nature of the problem. AFAICS, the bug is not dependent on the particular file chosen, it occurs for any large text file. <?php $trigger_bug=TRUE; $file = "http://www.mersenneforum.org/txt/43.txt";; if (!($fp = fopen($file, "r"))) { die("could not open XML input from $file"); } $chunkno=1; $total=0; while($data=fgets($fp,10000)) { $total+=strlen($data); if($trigger_bug) { print "chunk $chunkno, total ".$total." (+".strlen($data)."), eof: ".(feof($fp)?1:0)."<br/>\n"; } else { print "chunk $chunkno, total ".$total." (+".strlen($data).")<br/>\n"; } $chunkno++; } fclose($fp); ?> With $trigger_bug set to true, this will terminate before all of the file is read. With $trigger_bug set to false it will read the entire file. Note that the only difference between the two is that the script displays the output of feof($fp). This bug started to bite us when we upgraded from 5.2.1 to 5.2.11, it is not present in 5.2.1 / 5.1.4. ------------------------------------------------------------------------ [2009-10-11 17:08:44] travian dot utils at gmail dot com Description: ------------ feof() reached end of stream while reading big HTTP response from socket using fgets.
