Parameters
A parameter is a local variable
whose value is passed to the function by the calling code.
Parameters are declared in a
parameter list as part of the function declaration:
function myTest($para1,$para2,...)
{

}

}
Parameters are also called
arguments. We will discuss them in more detail when we talk about functions.
A string variable is used to store
and manipulate text.
