Rule ``phpdoc_scalar``
======================

Scalar types should always be written in the same form. ``int`` not ``integer``,
``bool`` not ``boolean``, ``float`` not ``real`` or ``double``.

Configuration
-------------

``types``
~~~~~~~~~

A list of types to fix.

Allowed values: a subset of ``['boolean', 'callback', 'double', 'integer', 'real', 'str']``

Default value: ``['boolean', 'callback', 'double', 'integer', 'real', 'str']``

Examples
--------

Example #1

*Default* configuration.

.. code-block:: diff

    <?php
    /**
   - * @param integer $a
   - * @param boolean $b
   - * @param real $c
   + * @param int $a
   + * @param bool $b
   + * @param float $c
     *
   - * @return double
   + * @return float
     */
    function sample($a, $b, $c)
    {
        return sample2($a, $b, $c);
    }
