记录日记

一定要引入vendor/autoload.php 否则无法使用monolog

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

  require_once __DIR__ . '../../../../../api/v1/vendor/autoload.php';

// log setting.
$log = new Logger('email');
$month = date('Y-m');
// 这是当前文件夹下建立一个专门存日记的文件夹
$log->pushHandler(new StreamHandler(__DIR__ . '/log/email_' . $month . '.log', Logger::DEBUG));

$log->info('Start processing...', ['wo_id' => $wo_id]);



// 这是一个实例
        try {
            $result = send_email($send_email, $mail_subject, $content, $content);
        } catch (Exception $e) {
            $log->error('email sending error');
        }

 日记2:

echo __DIR__;

$log=123123123;
file_put_contents(__DIR__.'/splogs/12312.txt', $log, FILE_APPEND);

日记3：

 function wh_log($log_msg) {
    $log_filename = $_SERVER['DOCUMENT_ROOT']."/log";
    if (!file_exists($log_filename))
    {
        // create directory/folder uploads.
        mkdir($log_filename, 0777, true);
    }
    $log_file_data = $log_filename.'/log_' . date('d-M-Y') . '.log';
    file_put_contents($log_file_data, $log_msg . "\n", FILE_APPEND);
}

 monolog 日记封装：

<?php

namespace Shared;

use PDOStatement;
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
use Monolog\Formatter\LineFormatter;

class Logging
{
    private $logger;
    private $dateFormat = 'Y-m-d H:i:s';
    private $output = "%datetime% %message%\n";

    public function __construct($name = '', $db_name = 'mic00001')
    {
        if ($name === '') {
            $name = 'logs_' . Date('Y-m');
        }

        $this->logger = new Logger('eamic');

        $path = __DIR__ . '/../../../files/' . $db_name;
        if (file_exists('/mnt/disk01/files/' . $db_name)) {
            $path = '/mnt/disk01/files/' . $db_name;
        }

        $path .= '/logs/' . $name . '.txt';

        $stream = new StreamHandler($path, Logger::DEBUG);
        $formatter = new LineFormatter($this->output, $this->dateFormat);
        $stream->setFormatter($formatter);
        $this->logger->pushHandler($stream);
    }

    public function write($log)
    {
        // Ensure that the variable $log is a string
        if ($log instanceof PDOStatement) {
            $log = implode(' ', array_slice($log->errorInfo(), 2));
        } elseif (!is_string($log)) {
            $log = json_encode($log);
        }

        $this->logger->debug($log);
    }
}
