I just found out that my webhost discontinued PHP4, and even though everyone says PHP5 is backwards comaptible, I seem to have some PHP4 code that does not work anymore. I am hoping someone out there can tell me why? I am very new to PHP so I am not very good at figuring this out myself. The code snippet that doesn't work is below - if anyone can tell me if its easier to modify the code or just move to a web host that supports PHP4, I would much appreciate it!

    doesn't work

    very vauge, how about giving us error messages or at least someting to go on.

      As dagon points out, supplying us with the error messages (you've got a parse error, for example) would be a good idea.

      One problem I noticed immediately was this code:

      	$str = "thisD";
print $str;

      You can't have a random variable and/or statement in the middle of a class definition.

      EDIT: That code also causes a parse error in PHP 4.

        Sorry to be so vague about "doesn't work" - but I don't know how else to describe it becuase the page simply comes up blank: http://www.platopettreats.com/locator --

        The page pulls up about 12 different PHP files & includes, and I tracked it down to the page that I linked (code linked above) as the place where it stops printing my $echo "here i am" messages.

        Is there a way to get PHP to write the error perhaps to help with this discussion?

          Oh and this is just my troubleshooting - the code breaks with or without this
          $str = "thisD";
          print $str;

            Yes, of course - that's what the [man]display_errors[/man] and [man]error_reporting[/man] PHP directives are for; change them either in the php.ini file itself, or in a .htaccess file (if you're using Apache and PHP is loaded as an ISAPI module rather than a CGI binary).

            With that "troubleshooting" code (which would more aptly be named "trouble-causing" code), the script contains a parse error. Without it, there are no parse errors.

              I've put the below in my .htacces file in the root, but still no errors showing up on the main page when loaded:
              http://www.platopettreats.com/locator/

              this is in my .htaccess to try & see the errors

                If you do a phpinfo(), what does PHP report for the "Server API" ?

                Does your host allow you to change PHP directives in a .htaccess file, or do they instead suggest you make the changes in a custom php.ini file placed at a certain location?

                Are you not developing your site in local test/development environment? :p
