Description:
------------
It seems that since the changes introduced after PHP 4.3.1, the feof
function is no longer returning true when the server closes the socket
connection after transmiting all the contents.
This seems to make it impossible to determine if there was a real
network error or the server closed the connection normally breaking the
compatibility of scripts that rely on feof to determine the end of
connection condition.
Reproduce code:
---------------
The following script demonstrates the change of behaviour. You should
try it either PHP versions before and after PHP 4.3.2 to see the
difference.
<?php
$socket=fsockopen("www.php.net",80,$error);
if(!$socket)
{
echo "socket opening error\n";
exit;
}
echo "connection opened\n";
if(!fputs($socket,"GET / HTTP/1.1\r\nHost:
www.php.net\r\n\r\n"))
{
echo "socket writing error\n";
exit;
}
while(!feof($socket))
{
$data=fread($socket,1000);
if(!$data)
{
echo "socket reading error\n";
exit;
}
echo "read ",strlen($data)," bytes\n";
}
echo "reached the end of data\n";
fclose($socket);
?>
Expected result:
----------------
connection opened
read 1000 bytes
read 1000 bytes
read 1000 bytes
read 1000 bytes
read 1000 bytes
read 1000 bytes

read 1000 bytes
