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  :-[

$var = "text";

function func(){
echo $var;
}

func();

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?

$var = "text";

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

func();
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...

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)
