Bug description: echo "0"; terminates output
Description:
------------
(Hard to reproduce.)
In one of my scripts any variant of outputting a variable set to (string)
"0" ended the output. Appearantly happened for var_dump(), print_r(),
echo() and print().
Initially it appeared to be a pcre problem:
$_SERVER["QUERY_STRING"] = "q=example&s=0&s=1&s=7";
preg_match_all('/&s=(\d+)/', $_SERVER["QUERY_STRING"], $uu);
echo implode(" ", $uu[1]);
But it probably isn't. Appears that earlier parts of any of the other
included scripts changed interpreter behaviour and lead to the strange
effect. It seems not configuration-related or to be a general bug, as the
same <?php echo "0";' ?> gives no problem in short scripts.
Only fails in CGI environment, doesn't happen on cmdline.
same effect:
- echo "0";
- echo '0';
OTH this doesn't output anything strange (binary):
- echo "1";
Not sure, if this is a bug at all. The "0" breaks also with 5rc2, 4.3.x
and down to 4.1.2 (all in -cgi/fcgi incarnation)
But btw:
echo "\000"; echo "+++";
echo "0"; echo "...";
will correctly return the [EMAIL PROTECTED] but nothing after that.
related to #16388 ?
Reproduce code:
---------------
<?php
//...
#...
#
include("htm/head"); # contains no php code
echo "0"; # ends output
// more code follows
#... (all other code and include()s being commented out to reproduce)
?>
