Methods
formatMemory()
public
static formatMemory(int $memory) : mixed
Parameters
- $memory : int

mixed —formatTime()
public
static formatTime(mixed $secs) : mixed
Parameters
- $secs : mixed

{@inheritdoc}
public
getName() : string
Return values
string —length()
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
int —mustRun()
Runs the process.
public
mustRun(OutputInterface $output, array<string|int, mixed>|Process $cmd[, string $error = null ][, callable|null $callback = null ]) : 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
- $callback : callable|null = null
-
A PHP callback to run whenever there is some output available on STDOUT or STDERR

Runs an external process.
public
run(OutputInterface $output, array<string|int, mixed>|Process $cmd[, string $error = null ][, callable|null $callback = null ][, int $verbosity = OutputInterface::VERBOSITY_VERY_VERBOSE ]) : Process
Parameters
- $output : OutputInterface
- $cmd : array<string|int, mixed>|Process
-
An instance of Process or an array of the command and arguments
- $error : string = null
- $callback : callable|null = null
-
A PHP callback to run whenever there is some output available on STDOUT or STDERR
