SeasLog::critical — Record critical log information
Record critical log information.
注意:
"CRITICAL" - Critical conditions.Need to be repaired immediately, and the program component is unavailable.
messageThe log message.
contentThe `message` contain placeholders which implementors replace with values from content array. Sush as `message` is `log info from {NAME}` and `content` is `array('NAME' => neeke)`, the log information will `log info from neeke`.
loggerThe `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 TRUE on record log information success, FALSE on failure.
例1 SeasLog::critical() example
<?php
var_dump(SeasLog::critical('log message'));
//with content
var_dump(SeasLog::critical('log message from {NAME}',array('NAME' => 'neeke')));
//with tmp logger
var_dump(SeasLog::critical('log message from {NAME}',array('NAME' => 'neeke'),'tmp_logger'));
var_dump(SeasLog::getBuffer());
