Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
Please read the manual carefully:
"Returns a string of up to length - 1 bytes read from the file pointed
to by handle. Reading ends when length - 1 bytes have been read, on a
newline (which is included in the return value), or on EOF (whichever
comes first)."
versions < 4.3 were not following this behaviour.
However, what this really means is that your script is broken; if you
are expecting "ACK\r\n", you should be using fread() to read 5 bytes
and then check the return value.

Description:
------------
PHP 4.2.3 works as I would expect. When doing an fgets($string,3) I get
3 char's returned, in my instance ACK.
as from 4.3.1 up to and including the new 5.0b the same code only
returns AC I then have to do a further fgets to collect the K of my
packet.
Reproduce code:
---------------
<?php
$connect_to = "localhost";
print "Connecting To: $connect_to <br>";
$fp = fsockopen ($connect_to,2100,&$error,$errdesc,60);
$out_data = "This is a test. Expecting 'ACK' returned followed a
string of data";
fputs($fp,$out_data);
$page = fgets($fp,3);
print "in1: $page <br>";
$page = fgets($fp,512);
print "in2: $page <br>";
?>
Expected result:
----------------
in1: ACK
in2: The rest of my data
Actual result:
--------------
in1: AC
in2: KThe rest of my data
