Using predefined variables inside functions

Recommended Posts

I know that to get the code below to work, i could put $var in both func() brackets - but - is there any way around this? If i had say 10 variables, i would have to put them all in the brackets - and to me thats not very modular if you are going to have quite a few functions in a page  :-[

[code]$var = "text";

function func(){
echo $var;
}

func();
[/code]

It depends on your function, if it is always expecting the same 10 arguments, yes, you need to add them. Alternatively, you might want to look into func_get_args(). I don't understand what you mean about it not being very modular, maybe that is down to your system design?

[code]
$var = "text";

function func(){
global $var;
echo $var;
}

func();
[/code]
this will echo "text" but you need to read into variable scope to understand the difference between this and passing it as an argument, etc..

also, you might want to give a little background info as to what you are wanting to do...
