What is the difference between ceilMinute and ceilMinutes in PHP Carbon?-CodePudding

In the Carbon.php source file that comes with Laravel 8 it shows

 * @method        $this               ceilMinute(float $precision = 1)                                                     Ceil the current instance minute with given precision.
 * @method        $this               ceilMinutes(float $precision = 1)                                                    Ceil the current instance minute with given precision.

Basic testing shows that given input "2021-11-26 11:25:10.000000", both functions round it up to "2021-11-26 11:26:00.000000".

And I want to know is there any difference between these two functions?

Any help would be appreciated.

Short answer: they're 100% equivalent.

Carbon implements almost everything using magic methods. The implementation of __call() basically strips trailing s:

/**
 * Dynamically handle calls to the class.
 *
 * @param string $method     magic method name called
 * @param array  $parameters parameters list
 *
 * @throws UnknownMethodException|BadMethodCallException|ReflectionException|Throwable
 *
 * @return mixed
 */
public function __call($method, $parameters)
{
    // [...]
    $unit = rtrim($method, 's');

... and uses that to fetch a value from the units list:

    if (\in_array($unit, static::$units)) {
        return $this->setUnit($unit, ...$parameters);
    }

protected static $units = [
    // @call setUnit
    // @call addUnit
    'year',
    // @call setUnit
    // @call addUnit
    'month',
    // @call setUnit
    // @call addUnit
    'day',
    // @call setUnit
    // @call addUnit
    'hour',
    // @call setUnit
    // @call addUnit
    'minute',
    // @call setUnit
    // @call addUnit
    'second',
    // @call setUnit
    // @call addUnit
    'milli',
    // @call setUnit
    // @call addUnit
    'millisecond',
    // @call setUnit
    // @call addUnit
    'micro',
    // @call setUnit
    // @call addUnit
    'microsecond',
];
