Please explain in more detail, or give some of your code.

So, when you try to echo the value at the end, it returns undefined?

Perhaps it is in a function. With a function you must declare that the variable is global, at the beginning of the function.

Code:

$var1 = "hello";

function sayHello()
{
  echo $var1; //will give an undefined notice
}

function globalHello()
{
  global $var1;
  echo $var1; //will give "hello"
}

hi
The old way is like this

$var1 = "hello";
function globalHello($var1)
{
echo $var1; //will give "hello"
}

Thanks
