Hi Shahar,
This operation may fit nicely as:
class Zend_Filter_StringByteLength implements Zend_Filter_Interface
{
/**
* Returns the length in bytes of the string $value
*
* @param string $value
* @throws Zend_Filter_Exception If determining byte length is
impossible
* @return integer
*/
public function filter($value)
{
/**
* @todo Implementation
*/
}
}
or something similar?
Best regards,
Darby
