Re: [PHP] Container functions....

Mike,

developer_execute() {
 execute this code only
}

declare it in an include file or something:

<?
developer_execute() {
        if($_SERVER['REMOTE_ADDR'] == "000.000.000.000") {
                echo "i've done something just for ip 000.000.000.000";
        } else {
                echo "";
        }
}
?>


execute it anywhere you like:

<?
developer_execute();
?>


So, the above will execute if your ip address is the same as the one in the function, which seems to be what you want, although I don't like the idea of code relying on an IP address because:

- it might change
- an ip can be spoofed


Consider the following pseudo code:

domain based as per my last email

function local_only()
        {
        if(domain is LAN domain)
                {
                // do this
                }
        }

or session based with a logged in user of the right clearance level

function developer_only()
        {
        if($_SESSION['auth_level'] = 'developer')
                {
                // do this
                }
        }


I just wouldn't rely on an IP of the remote user.

Not ColdFusion - ancient language by Brian Fox called MetaHTML - actually a
VERY good language - just not supported or developed anymore as far as I can
tell ;)

Anyhow - that is one solution that I had not thought of - but ideally I
would like to use a function rather than an IF statement - just the anal
developer attutude that is in me ;)

For instance, in an IF statement, is there a way to reference, or access the
code/etc contained within the { } ? If there was, then this solution:

developer_execute() {
 execute this code only
}

Where the function developer_execute would be defined as:
function developer_execute() {
    if(getenv("REMOTE_ADDR")=="000.000.000.000") {
        %body
    }
}

Would work - I am just hitting the wall as to how to reference the code
between { and } represented in the function definition by %body

Anybody?

Sounds like you're trying to replicated something in ColdFusion?

I have a few blocks of code on my pages which are only executed on my
development server, not the live server -- is this what you want?

if(ereg("192.168.0.",$_SERVER['SERVER_ADDR']))
{
$local = 1;
}
else
{
$local = 0;
}


if($local)
{
// do whatever you want
}

In a language that I used to program in - for development we used to
be able
to make a function that basically just executed everything inbetween:
<hidecode>
Print "This is html printed" <some programming code> Print "this is
more
code";
</hidecode>

So basically everything in between hidecode and /hidecode is executed
the
same as if the hide code did not exist - except that the hidecode
container
would be something like:

Function hidecode() {
    if(getenv("remoteaddress")=="myaddress") {
        %s (all code contained within the tags)
    }
}

So - the question is does PHP have some way that I cannot see to do
this?

I realize that I could create a function and pass everything in as an
argument - but that would involve putting everything into variables,
and
overall being just a pain in the ass to add and remove the container.

Is PHP too sophisticated a language to be able to do this easily and
quickly?  Or am I just missing some form of function that is totally
obvious?

Finally - yes, I know that I could slap an if tag around it - but that
is
also a big pain in the ass to add and remove each if tag when you go
'live'
with the change, as opposed to a quick find and replace with a
container
function like this...

TIA
