You can do anything you want... :)
<?php
class StrictProps
{
private $___init = true;
function StrictProps( $props )
{
$propsList = func_get_args();
foreach( $propsList as $props )
{
if( is_array( $props ) )
{
foreach( $props as $prop => $init )
{
$this->{$prop} = $init;
}
}
else
{
$this->{$props} = null;
}
}
$this->___init = false;
}
function __set( $name, $value )
{
if( !$this->___init )
{
die( 'Attempt to set non-existent property: '
.get_class( $this ).'->'.$name."\n" );
}
$this->{$name} = $value;
}
function __get( $name )
{
die( 'Attempt to get non-existent property: '
.get_class( $this ).'->'.$name."\n" );
}
}
//
// Declare strict properties...
//
$my = new StrictProps( 'foo', 'fee', 'fii' );
print_r( $my );
//
// Declare and intialize strict properties...
//
$my = new StrictProps( array( 'foo' => 'Foo1', 'fee' => 'Fee1' ) );
print_r( $my );
echo $my->foo."\n";
echo $my->fee."\n";
echo $my->blah."\n";
?>
Cheers,
