RE: [PHP] Subroutines
they're just functions
function your_function($arg1,$arg2){
echo $arg1;
echo $arg2;
}

Subject: [PHP] Subroutines
I've looked through the manual (or at least searched) for subroutines, and I
can't find them, there's a guy I know who made a script with custom PHP
subroutines. (http://b000.net/) Anyway, I want to know how to make them.
Thanks for any input.

RE: [PHP] subroutines?
Hi again,
As a new PHP convert, I ran into this same problem (below) yesterday while
designing a form. ASP programmers (if they're THINKING) will use subs to
keep if blocks tidy. In ASP, I'd use something like:
If Request.ServerVariables( REQUEST_METHOD ) = GET Then
DisplayForm
Else
SendFormData
End If
which at first I replaced with:
if ( getenv( REQUEST_METHOD ) == GET ) {
display_form();
} else {
send_email();
}
...making functions out of what used to be subroutines. All well-and-good,
except my global variables disappeared and nothing I could do (even
declaring the few important ones explicitly global) seemed to allow me to
get at the variable contents.
I wound up compromising by sending just the bits I needed in the function
INTO the function like so:
$MyURI = $SCRIPT_NAME;
$TheFormVars = $HTTP_POST_VARS;
if ( getenv( REQUEST_METHOD ) == GET ) {
display_form( $MyURI );
} else {
send_email( $TheFormVars, $ThisWebServerFQDN );
}
Seems a bit tacky at first, but it works (properly!) and that's all that
counts. I can do much more with PHP functions just as they are than I ever
could with ASP; moreover, I have much more secure control of what gets
exposed where. To me, a beautiful compromise since at no point is there
ever an actual email address exposed to the outside world. My Support
Topic selection box contains arbitrary codes that allow me to generate the
appropriate email address on the fly.
Hope my experience will be helpful to other noobies making the Big
Transition.
Best regards,
Bill

Bill,
You need to declare the variables global within each function that access
them or access the variable via the $GLOBALS array.
$var = 'something';
function go()
{
return $GLOBALS[var];
}
or
function go()
{
global $var;
return $var;
}
echo go();

Re: [PHP] subroutines?
Jason pretty well suggested what to use. PHP scripts with a lot of logic in them usually have all the function definitions and logic at the top of the script and the display stuff at the end. Again, as I'm always recommending, have a look at Julie Meloni's Thickbook tutorials, particularly the custom error messages example. http://www.thickbook.com Have fun - Miles At 04:37 PM 8/7/01 -0700, CGI GUY wrote: How does PHP compensate for an apparent lack of traditional subroutines (as with Perl, etc.)?
