[SOLVED] Passing Vars to Funtions

[siwelis]

$var1;

 

function Test(){

echo $var1;

}

 

function()

 

------------------------

 

Can anyone tell me why the function doesn't recognize predermined vars?

global

 

Variables set inside a function are available only to that function. Vars set outside that function are only available to items outside functions.

 

You need to look in the manual regarding the scope of variables.

$var1=4;
$var2=3;
$var3=6;

function Test(){
global $var1,$var2,$var3;
echo $var1+$var2+$var3;
}

Test();

 

This returns 13

 

If you drop out the global, those variables are not available inside the function.
