#!O:/php/perl/bin/Perl.exe
print "Content-type:text/html\n\n";
print "<center><h2>Hello World</h2></center>;
#这里少了一个“ 号
exit; www.shengfang.org

SYNOPSIS
    use CGI::Carp;
    croak "We're outta here!";
    confess "It was my fault: $!";
    carp "It was your fault!";  
    warn "I'm confused";
    die  "I'm dying.\n";
    use CGI::Carp qw(cluck);
    cluck "I wouldn't do that if I were you";
    use CGI::Carp qw(fatalsToBrowser);
    die "Fatal error messages are now sent to browser";

--------------------------------------------------------------------------------

DESCRIPTION
CGI scripts have a nasty habit of leaving warning messages in the error logs that are neither time stamped nor fully identified. Tracking down the script that caused the error is a pain. This fixes that. Replace the usual

    use Carp;
with

    use CGI::Carp
And the standard warn(), die (), croak(), confess() and carp() calls will automagically be replaced with functions that write out nicely time-stamped messages to the HTTP server error log.

For example:

   [Fri Nov 17 21:40:43 1995] test.pl: I'm confused at test.pl line 3.
   [Fri Nov 17 21:40:43 1995] test.pl: Got an error message: Permission denied.
   [Fri Nov 17 21:40:43 1995] test.pl: I'm dying.
