Example of getters and setters in PHP.

Example.php

<?php

$foo = new Foo();

$foo->id = 1;
$foo->text = 'Hello';

echo $foo->id; // 1
echo $foo->text; // Hello World!

Foo.php

<?php
/**
 * @property int $id
 * @property string $text
 */
class Foo
{
    protected $id;
    protected $text;

    public function __get($name)
    {
        $methodName = 'get' . ucfirst($name);
        return method_exists($this, $methodName) ? $this->{$methodName}() : $this->{$name};
    }

    public function __set($name, $value)
    {
        $methodName = 'set' . ucfirst($name);
        return method_exists($this, $methodName) ? $this->{$methodName}($value) : $this->{$name} = $value;
    }

    public function __isset($name)
    {
        return property_exists($this, $name);
    }

    public function setText($text)
    {
        $this->text = $text . ' World!';
    }
}

Great idea.I would use
protected function setText($text)
