<?php
class Foo
{
private $bar = 0; // cannot normally be accessed outside of the class
public function __set($var, $value)
{
if ($var == 'bar') {
// force value to be integer
$this->$var = (int)$value;
} else {
throw new Exception("Invalid varname '$var'");
}
}
public function __get($var)
{
if ($var == 'bar') {
return $this->$var;
}
throw new Exception("Invalid varname '$var'");
}
}
try {
$test = new Foo();
$test->bar = 99;
echo $test->bar; // 99
echo "<br />n";
$test->bar = '123.456';
echo $test->bar; // 123
$test->xxx = 333; // throws exception
}
