It iterates over the entire array until it finds the $handlerKey that was identified earlier using isHandling(). Once the starting position is found it will execute handle() on each handler unless a handler returns true indicating the handler completed the processing of the record, bubbling to the next handler should not occur, and the loop breaks.
This fixes an issue where an associative array of handlers is passed into the Logger constructor when instantiated.

Introduce a new `useMicrosecondTimestamps()` method to Logger that
allows runtime selection of whether or not to create microsecond
resolution timestamps for log records.
Generating microsecond resolution timestamps by calling
`microtime(true)`, formatting the result via `sprintf()` and then
parsing the resulting string via `DateTime::createFromFormat` can incur
a measurable runtime overhead vs simple usage of `new DateTime` to
capture a second resolution timestamp in systems which generate a large
number of log events.
The default behavior of generating high precision timestamps remains the
same, but may be changed in a future release. Users requiring high
precision timestamps are encouraged to explicitly call
`Monolog\Logger::useMicrosecondTimestamps(true)` in their setup code.
Closes#657
Logger::setHandlers() is intended to help dependency injection systems
that deal more elegantly with property setters than constructor
arguments. Alongside getHandlers(), pushHandler(), popHandler(), it is
a logical addition to the API.
It also attempts to address some possible errors in the format of the
data passed:
- If a map is passed, the keys are removed, as these aren’t expected
by Monolog
- If falsey values are included, these are stripped
It relies on Logger::pushHandler() internally, so that if any special
behaviour is added in the future, this only needs to be added in one
place.
Add a setter method to allow changing the timezone used when creating
new log records. This provides a means to correct a behavioral change
introduced by 6cbdc04 where use of the PHP runtime default timezone
provided by `date_default_timezone_get()` was introduced. In most
environments the new default behavior is preferable, but if an
application allows the default timezone to vary between requests it
causes confusing log output.
is initialized without the DateTimeZone instance, the underline library
execute a stat('.../Europe/Paris') to check if the OS knows the timezone.
This will improve performance on long run process by avoiding unless i/o calls.
- constants defined for the 2 missing levels: NOTICE and EMERGENCY.
- add<level>() and <level>() convenience methods added.
- TestHandler and tests updated to account for the two extra levels.
- surjective mappings from the RFC3164 to only 6 levels changes to bijective.
- README updated accordingly.
