  • throws \InvalidArgumentException when the given format is not supported
public static Symfony\Component\Console\Helper\Helper::formatMemory(int $memory) : string
public static Symfony\Component\Console\Helper\Helper::formatTime(int|float $secs, int $precision = 1) : string
public getFormats() : array
public Symfony\Component\Console\Helper\Helper::getHelperSet() : ?Symfony\Component\Console\Helper\HelperSet
public getName() : string
public static Symfony\Component\Console\Helper\Helper::length(?string $string) : int
 

Returns the length of a string, using mb_strlen if it is available.

The length is related to how many bytes the string will use.

public register(string $format, Symfony\Component\Console\Descriptor\DescriptorInterface $descriptor) : static
 

Registers a descriptor.
