formatMemory()
    public
            static        formatMemory(int $memory) : string
    Parameters
- $memory : int
 
Return values
stringformatTime()
    public
            static        formatTime(int|float $secs[, int $precision = 1 ]) : string
    Parameters

Return values
stringgetHelperSet()
Gets the helper set associated with this helper.
    public
                    getHelperSet() : HelperSet|null
    Return values
HelperSet|nullgetName()
Returns the canonical name of this helper.
    public
                    getName() : string
    Return values
stringlength()
Returns the length of a string, using mb_strlen if it is available.
    public
            static        length(string|null $string) : int
    The length is related to how many bytes the string will use.
Parameters
- $string : string|null
 
Return values
intmustRun()
Runs the process.
    public
                    mustRun(OutputInterface $output, array<string|int, mixed>|Process $cmd[, string|null $error = null ][, callable|null $callback = null ][, int $verbosity = OutputInterface::VERBOSITY_VERY_VERBOSE ]) : Process
    This is identical to run() except that an exception is thrown if the process exits with a non-zero exit code.
Parameters
- $output : OutputInterface
 - $cmd : array<string|int, mixed>|Process
 - 
                    
An instance of Process or a command to run
 - $error : string|null = null
 - $callback : callable|null = null
 - 
                    
A PHP callback to run whenever there is some output available on STDOUT or STDERR
 - $verbosity : int = OutputInterface::VERBOSITY_VERY_VERBOSE
