Description

I register a shutdown function in php. In this shutdown function I try to log something unsing Log4php.

actual:
No Log entries for any log call within the shutdown function.

expected:
Log entries from the shutdown function.

Exemple Code, config file and shell output:

• • • • • • log4php_conf.xml *******
            <?xml version="1.0" encoding="UTF-8"?>
            <configuration xmlns="http://logging.apache.org/log4php/">
            <appender name="myAppender" class="LoggerAppenderFile">
            <layout class="LoggerLayoutTTCC" />
            <param name="file" value="test.log" />
            </appender>
            <root>
            <level value="TRACE" />
            <appender_ref ref="myAppender" />
            </root>
            </configuration>

---------------------------------------------------------------------

• • • • • • • test.php *******
              <?php

require_once './log4php/Logger.php';

Logger::configure('./log4php_conf.xml');

$logger = Logger::getLogger("ShutdownTest");

main();

function main() {
global $logger;
$logger->trace("function main() called");
$logger->info("*** start shutdown test ***");
register_shutdown_function('shutdown');
print("\ndo something ... ");
sleep(1);
print("done\n");
}

function shutdown(){
global $logger;
$logger->trace("function shutdown() called");
// do some stuff like logging errors ...
$logger->info("*** exiting shutdown test ***");
print("This line is printed out.\n");
}
?>
