説明

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

The Common Record Log Function.

パラメータ

level

Can use level in:

Or you can create a new level self-help.

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::log example

<?php

var_dump(SeasLog::log(SEASLOG_INFO,'info log'));
var_dump(SeasLog::getBuffer());

//create a new level self-help.
var_dump(SeasLog::log('MySelfLevel','info log'));
var_dump(SeasLog::getBuffer());

//with `content`
var_dump(SeasLog::log('MySelfLevel','info log {NAME}',array('NAME' => 'neeke')));
var_dump(SeasLog::getBuffer());

//with `logger`
var_dump(SeasLog::log('MySelfLevel','info log {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)
