一种方法来做到这一点（假设你在Laravel 5.0+上）：
PrependsOutput.php

<?php 
namespace App\Console\Commands;
trait PrependsOutput
{
    public function line($string)
    {
        parent::line($this->prepend($string));
    }
    public function comment($string)
    {
        parent::comment($this->prepend($string));
    }
    public function error($string)
    {
        parent::error($this->prepend($string));
    }
    public function info($string)
    {
        parent::info($this->prepend($string));
    }
    public function warn($string)
    {
        parent::warn($this->prepend($string));
    }
    protected function prepend($string)
    {
        if (method_exists($this, 'getPrependString')) {
            return $this->getPrependString($string).$string;
        }
        return $string;
    }
}

字符串
PrependsTimestamp.php

<?php
namespace App\Console\Commands;
trait PrependsTimestamp
{
    protected function getPrependString($string)
    {
        return date(property_exists($this, 'outputTimestampFormat') ?
            $this->outputTimestampFormat : '[Y-m-d H:i:s]').' ';
    }
}

型
在你的命令下：

<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
class MyCommand extends Command
{
    use PrependsOutput, PrependsTimestamp;
    protected $signature = 'mycommand';
    protected $description = '';
    // you can override the default format
    // protected $outputTimestampFormat = '(m/d/Y H:i:s)';
    public function handle()
    {
        $this->comment('comment');
        $this->info('info');
        $this->warn('warn');
        $this->error('error');
        $this->line('line');
    }
}

结果：

的数据

从laravel 5.5开始，你可以添加这个特性。
并在控制台命令中使用它

<?php
namespace App\Console;
trait PrependsTimestamp
{
    public function line($string, $style = null, $verbosity = null)
    {
        $timestamped = date('[Y-m-d H:i:s] ') . ucfirst($style) . ': ' . $string;
        $styled = $style ? "<$style>$timestamped</$style>" : $timestamped;
        $this->output->writeln($styled, $this->parseVerbosity($verbosity));
    }
}

字符串

相同输出：

的数据

@peterm的答案针对Laravel 5.8（可能更早）进行了调整：

• 需要遵循line()的父方法签名。
• 重写line()足以为所有输出类型前置文本

PrependsOutput.php

<?php 
namespace App\Console\Commands;
trait PrependsOutput
{
    public function line($string, $style = null, $verbosity = null)
    {
        parent::line($this->prepend($string), $style, $verbosity);
    }
    protected function prepend($string)
    {
        if (method_exists($this, 'getPrependString')) {
            return $this->getPrependString($string) . $string;
        }
        return $string;
    }
}

字符串
