/****************************************************************************************************

        This example demonstrates how to :
        - Create a variable store and initialize it with a set of variable name/value pairs.
        - Show the contents of the store, expanding the variable values or not
        - Show the contents of a variable after expansion

     ****************************************************************************************************/

   
require_once ( '../Variables.phpclass' ) ;

    if (
php_sapi_name ( ) != 'cli' )
        echo
"<pre>" ;

   
// Initialization values for variables - 3 variables are defined here, 'word1', 'word2' and 'sentence'
    // The 'sentence' variable value references variables 'word1' and 'word2'.
   
$variables =
       [
       
'word1' => 'Hello',
       
'word2' => 'world',
       
'sentence' => '$(word1) $(word2) !'
       
] ;

   
// Initialize the variable store
   
$store = new VariableStore ( $variables ) ;
   
   
// Show variable names and values, without expanding the references to existing variables in their values
   
echo "Defined variables (with no expansion) :\n" ;
   
print_r ( $store -> ToArray ( ) ) ;
    echo
"\n\n" ;

   
// Same, but variable values are expanded
   
echo "Defined variables (with expansion) :\n" ;
   
print_r ( $store -> ToArray ( true ) ) ;
    echo
"\n\n" ;

   
// Shows the expanded value of the 'sentence' variable - note that it requires the VariableStore::OPTION_RECURSIVE flag
    // to be set, which is the default
   
echo "Value of variable 'sentence' : " ; print_r ( $store [ 'sentence' ] ) ;
