This is a small fix for a warning I have noticed when running the
mezzio:swoole:stopcommand:Warning: Undefined array key 1 in /home/shlink/vendor/mezzio/mezzio-swoole/src/Command/IsRunningTrait.php on line 28It's caused when the
$pidsarray only has one element. Usingarray_padwe ensure the array is filled with nulls up to 2 positions, which keeps the same behavior but prevents the warning.
