[PHP] Question about the scope of functions

[Phillip S. Baker]

Greetings People,

Now basically I am trying to set up an easy way to have key value pairs 
listed in a DB, and then be able to call the name of the key as a variable 
later in the code of the page and list the corresponding value in the DB. I 
am almost there. However I just need to figure out some scope issues with 
functions.
I want to create variables with names on the fly through a function and 
have them last beyond the life of the function.
However I do not want to have to declare each key/variable as a global 
variable in the function, will defeat the purpose of this.

I have the following DB table
sao_key                         sao_value
app_past_enroll                         1
something                                       0
something_else                          1
yet                                             1
I have the following function
function key_value ( $mysql  )  {
        if ( $sao_row = $mysql -> fetchRow() )  {
                do {
                        ${"$sao_row[0]"} = $sao_row[1]; // Create a 
variablle to pull the radio variable name
                }       while ( $sao_row = $mysql -> fetchRow() );
        }
}

I have the following code
$sql = "SELECT sao_key, sao_value FROM staff_app_options
$sao = new MySQL ( $sql );      #       Create an object with the above query
key_value ( $sao );
echo 'Past Enrollment = ' . $app_past_enroll . NL;
echo 'something = ' . $something . NL;
echo 'something_else = ' . $something_else . NL;
echo 'yet = ' . $yet . NL;
So how do I get the script to read $app_past_enroll as a variable after it 
has been created by the function?

Thanks for your help.

Phillip
