PHP マニュアル: Record emergency log information

説明

public static bool SeasLog::emergency(string $message, array $content = ?, string $logger = ?)

Record emergency log information.

注意:
"EMERGENCY" - System is unusable.

パラメータ

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.

戻り値

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

例

例1 SeasLog::emergency example

<?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());

?>

上の例の出力は、たとえば以下のようになります。

bool(true)
bool(true)
bool(true)
array(2) {
  ["/var/log/www/default/20180707.log"]=>
  array(2) {
