Nulllogger.php

<?php

namespace Psr\Log;

/**
 * This Logger can be used to avoid conditional log calls.
 *
 * Logging should always be optional, and if no logger is provided to your
 * library creating a NullLogger instance to have something to throw logs at
 * is a good way to avoid littering your code with `if ($this->logger) { }`
 * blocks.
 */
require_once APPPATH . 'third_party/psr/log/src/Psr/Log/AbstractLogger.php';
class NullLogger extends AbstractLogger
{
    /**
     * Logs with an arbitrary level.
     *
     * @param mixed[] $context
     *
     * @throws \Psr\Log\InvalidArgumentException

请帮助我继续前进。目前，我使用MPDF 6。我想将其升级到PHP 8。

多作曲家安装而不是手册

Answer 1

trory也安装PSR日志。

composer require psr/log

我希望它会有所帮助。

我建议您不要在需要之前修改供应商文件中的任何代码。
