"EMERGENCY" - System is unusable.

Parameters

message: The log message.
content: The `message` contain placeholders which implementors replace with values from content array. Sush as `message` is `log info from ` and `content` is `array('NAME' => neeke)`, the log information will `log info from neeke`.
logger: The `logger` cased by the third param would be used right this right now, like a temp logger, when the function SeasLog::setLogger() called in pre content. If `logger` NULL or "", SeasLog will use lastest logger setted by SeasLog::setLogger().

Return Values

Return TRUE on record log information success, FALSE on failure.

Examples

//with tmp logger
var_dump(SeasLog::emergency('log message from ',array('NAME' => 'neeke'),'tmp_logger'));
