Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. or come up with SHORT example. Previous Comments: ------------------------------------------------------------------------ [2003-09-08 18:10:35] bret at levycodev dot com Description: ------------ I have an "HTTP requestor" class that I wrote many years ago using fsocketopen, fgets and fread. It works and has always worked up until I load PHP 4.3.3. If I backrev to 4.3.0rc2 (the last rev I was running) the code works again. Symptoms are this: I connect fine, I get the request sent fine, I see the server respond with the correct and full message, but the php client sometimes, but not always, does not see the whole response. Sometimes the fread doesn't return everything requested. IMHO, this is not the same problem as the other reported socket_xxx related bugs, but I fully admit that I have not looked at the source! Included is the class that sends/receives the http message (and yes, there is probably something in PHP now that does this all for me, but this always worked before, and still works in PHP <= 4.3.0rc2). There were a few recent changes (I think), like the timeout call and the removal of the call by reference on the fsocketopen call, to make php 4.3 happy.
