Custom Superglobals

[neoform]

is there a way to make a custom superglobal like $GLOBALS that is available in any namespace without having to use "global $varname" in each namespace.. ?

 

I'm currently using $GLOBALS['varname'] but it's pretty ugly.

What's wrong with using:

global $var1, $var2...

 

???

 

Orio.

you could write a pseudo function

<?php
function globals_NOT($var){
return $_GLOBALS['var'];
}
?>

It's nice to be able to have access toa variable like $_POST without having to declare it as a global each time you want to use it.

I think you are on the right track. Just create an array, such as your $GLOBALS and just declare that as a global when you need it:

 

global $GLOBALS;

 

Then you have access to all thos pseudo global variables with just one global variable.

its not a smart idea to do any of that as you are using resources beacuse you are lazy.

Don't be lazy when it comes to programming. This will you will start programming with short_tags enabled, register_globals and who knows what other bad-practice settings. You want to make your scripts as clean, readable and system-compatible as possible.

If the variables are something that should be global, declare them as global at the start of your functions. If it's not something that you function needs but it's not something very important (by something important I mean stuff such as a DB connection, some kind of setting etc'), simply pass it as a parameter to the function.

Of course, if these variables have a constant value, define them as constants with define().

Err, there's nothing wrong with using short_tags.. it's not bad code ethic since i've never seen a machine with php5 that doesn't have it enabled.

 

I use $GLOBALS right now to store a number of objects like my $GLOBALS['sql'] object that contains the mysqli object or $GLOBALS['tpl'] which is template object, both of which get used in pretty much every page on the site, this is exactly what superglobals were meant for, I just find it an ugly var name and would rather using something like $_SQL or $_TPL. Either way, using superglobals like this is not a bad practice.. I find "global $varname" to be far less clean.

[Orio]

Using short_tags or register_globals is bad practice. There are many machines that have them disabled, and it's not so difficult to write "<?php" instead of "<?" and "<?php echo" instead of "<?=".

Except that, you are always in a risk of causing problems with xml (that uses <?xml).

 

If you are looking for something "clean", define these important variables in an array called $_SQL or $_TPL or whatever, and at the start of every function use global on them. I did that alot in projects I have done before- it's clean, clear and easy to use.

Isn't that what I said?

[Orio]

You said superglobal, I said you should declare them global at the start of your functions.

No I didn't. I said

Just create an array, such as your $GLOBALS and just declare that as a global when you need it
