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

This is actually not a bug. Because the declare() stuff works as some
kind of conditional compile the functions will not be defined during
parsing/compile, but only when the code is executed for the first time.
Of course when the postdefined_in(); is reached the code below has not
been executed before and thus you can an undefined function error. The
same would happen if you'd put it in an if like this:

<?php

if (TRUE) {
    function blah1() {
    }

    blah1();
    blah2();

    function blah2() {
    }
}
?>

Same problem with 4.3.0RC4.

I just upgraded to version 4.3.0RC3 with the same
configure command, but the script gives the same message
as in the original posting.

This behavior is rather annoying, but a workaround is to 
declare the troublesome procedure *outside* the scope of
the 'declare(ticks=1) {}' block. However, this does not
seem to help if the new syntax 'declare(ticks=1);' is used
to cover the entire script under the declare() scope.

My configuration (as reported by phpinfo()):
./configure --with-apxs=/opt/httpd/bin/apxs 
 --with-mysql=/usr --with-gd 
 --with-curl=/opt/curl-7.10.1/ 
 --with-pdflib=/opt/pdflib/ 
 --with-zlib --enable-inline-optimizations 
 --enable-pcntl --enable-dio --with-ncurses 
 --enable-sockets
What I did (filename 'ticks_bug_php'):
--------------- CUT HERE --------------------
#!/usr/local/bin/php
<?php

        function predefined_out()
        {
                echo "Inside predefined_out()\n";
        }

        predefined_out();
        postdefined_out();

        function postdefined_out()
        {
                echo "Inside postdefined_out()\n";
        }

        declare(ticks = 1)
        {
                function predefined_in()
                {
                        echo "Inside predefined_in()\n";
                }

                predefined_in();
                postdefined_in();

                function postdefined_in()
                {
                        echo "Inside postdefined_in()\n";
                }
        }
?>
--------------- CUT HERE --------------------
What I expected:
 [avillaci@srv64 practica]$ ./ticks_bug_php 
 Inside predefined_out()
 Inside postdefined_out()
 Inside predefined_in()
 Inside postdefined_in()
 [avillaci@srv64 practica]$

What I got instead:

 [avillaci@srv64 practica]$ ./ticks_bug_php 
 Inside predefined_out()
 Inside postdefined_out()
 Inside predefined_in()

 Fatal error: Call to undefined function:  postdefined_in()     
 in /home/avillaci/programa/practica/ticks_bug_php on line
 25
 [avillaci@srv64 practica]$

PHP refuses to call postdefined_in() before its definition
inside the scope of 'declare(ticks=1){}', but has no problem
calling postdefined_out() before its definition, outside
the scope of 'declare(ticks=1){}'.
Any hints in solving this issue will be greatly appreciated.
