Answer 1

2 useful pieces of information:
(1) The previous answer by user367134 is helpful, however it has a bug: when setting the level you should not set it to the constant integer value denoted by LoggerLevel::DEBUG. You should instead make use of the LoggerLevel::toLevel() function to obtain a LoggerLevel object.
i.e.,
$rootlogger->setLevel(LoggerLevel::DEBUG);
Should instead be:
$rootlogger->setLevel(LoggerLevel::toLevel(LoggerLevel::DEBUG));
(2) Here is a similar example to the one above, with a few differences:
uses rolling log files (max size of each log file is 100MB and at most 10 are kept)
uses a custom pattern for the log lines
fixes the setLevel bug
sets the log level at INFO
The code:
$rootlogger = Logger::getRootLogger();
$rootlogger->setLevel(LoggerLevel::toLevel(LoggerLevel::INFO));
$appender = new LoggerAppenderRollingFile("MyAppender");
$appender->setFile("custom_name.log", true);
$appender->setMaxBackupIndex(10);
$appender->setMaxFileSize("100MB");
$appenderlayout = new LoggerLayoutPattern();
$pattern = '%d{Y-m-d H:i:s} [%p] %c: %m (at %F line %L)%n';
$appenderlayout->setConversionPattern($pattern);
$appender->setLayout($appenderlayout);
$appender->activateOptions();
$rootlogger->removeAllAppenders();
$rootlogger->addAppender($appender);
$rootlogger->info("info");

Well its not my code, But here is the sample code and link to the site
require_once('log4php/Logger.php');
$rootlogger = Logger::getRootLogger();
$rootlogger->setLevel(LoggerLevel::DEBUG);
$appender = new LoggerAppenderFile("MyAppender");
$appender->setFile("mylogfile.log", true);
$appenderlayout = new LoggerLayoutTTCC();
$appender->setLayout($appenderlayout);
$appender->activateOptions();
$rootlogger->removeAllAppenders();
$rootlogger->addAppender($appender);
$rootlogger->info("info");
$rootlogger->error("error");
$rootlogger->debug("debug");
