#29279 [NEW]: echo "0"; terminates output

From: milky at users dot sf dot net Operating system: Linux, glibc2.3 PHP version: 5.0.0 PHP Bug Type: Strings related 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 ^@+++ but nothing after that. related to #16388 ? Reproduce code: --------------- <?php //... #... # include("htm/head"); # contains no php code echo "0"; # ends output // more code follows #...
