PHP マニュアル: Record alert log information

説明

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

Record alert log information.

注意:
"ALERT" - Action must be taken immediately. Immediate attention should be given to relevant personnel for emergency repairs.

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.

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

var_dump(SeasLog::getBuffer());
