示例 #1 获取与设置根目录
<?php
$basePath1 = SeasLog::getBasePath();
SeasLog::setBasePath('/log/base_test');
$basePath2 = SeasLog::getBasePath();
var_dump($basePath1,$basePath2);
?>以上示例的输出类似于：
string(12) "/var/log/www" string(14) "/log/base_test"
示例 #2 获取与设置 Logger
<?php
$lastLogger1 = SeasLog::getLastLogger();
SeasLog::setLogger('testModule/app1');
$lastLogger2 = SeasLog::getLastLogger();
var_dump($lastLogger1,$lastLogger2);
?>以上示例的输出类似于：
string(7) "default" string(15) "testModule/app1"
示例 #3 快速写入日志
<?php
SeasLog::log(SEASLOG_ERROR,'this is a error test by ::log');
SeasLog::debug('this is a {userName} debug',array('{userName}' => 'neeke'));
SeasLog::info('this is a info log');
SeasLog::notice('this is a notice log');
SeasLog::warning('your {website} was down,please {action} it ASAP!',array('{website}' => 'github.com','{action}' => 'rboot'));
SeasLog::error('a error log');
SeasLog::critical('some thing was critical');
SeasLog::alert('yes this is a {messageName}',array('{messageName}' => 'alertMSG'));
SeasLog::emergency('Just now, the house next door was completely burnt out! {note}',array('{note}' => 'it`s a joke'));
?>日志的默认模板是 seaslog.default_template = "%T | %L | %P | %Q | %t | %M". 这意味着，在默认情况下，日志的记录格式是： `{dateTime} | {level} | {pid} | {uniqid} | {timeStamp} | {logInfo}`.
以上示例的输出类似于：
seaslog.appender = 1

以上示例的输出类似于：
seaslog.appender = 2 or seaslog.appender = 3

示例 #4 快速获取某级别下日志的数量
SeasLog 通过系统命令管道调用 `grep -wc` 获取数量，并返回给 PHP (返回数组或单个数值).
<?php
$countResult1 = SeasLog::analyzerCount();
$countResult2 = SeasLog::analyzerCount(SEASLOG_WARNING);
$countResult3 = SeasLog::analyzerCount(SEASLOG_ERROR,date('Ymd',time()));
var_dump($countResult1,$countResult2,$countResult3);
?>以上示例的输出类似于：
array(8) {
["DEBUG"]=>
int(3)
["INFO"]=>
int(3)
["NOTICE"]=>
int(3)
["WARNING"]=>
int(3)
["ERROR"]=>
int(6)
["CRITICAL"]=>
int(3)
["ALERT"]=>
int(3)
["EMERGENCY"]=>
int(3)
}
int(7)
int(1)
示例 #5 获取某级别下日志的详情
SeasLog 通过系统命令管道调用 `grep -w` 获取日志详情，并返回数组给 PHP.
<?php
$detailErrorArray = SeasLog::analyzerDetail(SEASLOG_ERROR);
var_dump($detailErrorArray);
var_dump(SeasLog::analyzerDetail(SEASLOG_ERROR,date('Ymd',time())));
?>以上示例的输出类似于：
array(6) {
