* Takes an associative array of arrays and inverts the array keys to values using the array values as keys.
*
* Example:
* $input = array(
* 'New' => array('1000', '1500', '1750'),
* 'Used' => array('3000', '4000', '5000', '6000')
* );
* $output = JArrayHelper::invert($input);
*
* Output would be equal to:
* $output = array(
* '1000' => 'New',
* '1500' => 'New',
* '1750' => 'New',
* '3000' => 'Used',
* '4000' => 'Used',
* '5000' => 'Used',
* '6000' => 'Used'
* );
*
* @param array $array The source array.
*
* @return array The inverted array.

* @deprecated 4.0 Use Joomla\Utilities\ArrayHelper::invert instead
