Short Type Names for PHP Codesniffer

PHP Codesniffer requires that scalar types be written in their long form, eg. boolean or integer.

As of PHP 7+, scalars are required to be written in their short form, eg. bool or int.

This patch allows you to use the short form in doc-block comments.

Before:

/**
 * Test function.
 *
 * @param integer $test A numeric argument.
 *
 * @return boolean Returns true or false.
 */
function test(int $test): bool
{
    return false;
}

After:

/**
 * Test function.
 *
 * @param int $test A numeric argument.
 *
 * @return bool Returns true or false.
 */
function test(int $test): bool
{
    return false;
}

Known Issues

This will not suggest bool/int if you have used boolean/integer - that would require patching PHP Codesniffer. A patch has been created, but not yet merged:
