Description

SeasLog::emergency(string $message, [array $content], [string $logger]): bool

Record emergency log information.

"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 {NAME}` 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

SeasLog::emergency() example

php
<?php

var_dump(SeasLog::emergency('log message'));

//with content
var_dump(SeasLog::emergency('log message from {NAME}',array('NAME' => 'neeke')));

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

var_dump(SeasLog::getBuffer());

?>
