本文实例讲述了tp5框架使用composer实现日志记录功能。分享给大家供大家参考，具体如下：

tp5实现日志记录

1.安装 psr/log

composer require psr/log

它的作用就是提供一套接口，实现正常的日志功能！

我们可以来细细的分析一下，LoggerInterface.php

<"foo".
 *
 * The context array can contain arbitrary data. The only assumption that
 * can be made by implementors is that if an Exception instance is given
 * to produce a stack trace, it MUST be in a key named "exception".
 *
 * See https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md
 * for the full interface specification.
 */
interface LoggerInterface
{
  /**
   * System is unusable.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function emergency($message, array $context = array());
  /**
   * Action must be taken immediately.
   *
   * Example: Entire website down, database unavailable, etc. This should
   * trigger the SMS alerts and wake you up.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function alert($message, array $context = array());
  /**
   * Critical conditions.
   *
   * Example: Application component unavailable, unexpected exception.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function critical($message, array $context = array());
  /**
   * Runtime errors that do not require immediate action but should typically
   * be logged and monitored.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function error($message, array $context = array());
  /**
   * Exceptional occurrences that are not errors.
   *
   * Example: Use of deprecated APIs, poor use of an API, undesirable things
   * that are not necessarily wrong.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function warning($message, array $context = array());
  /**
   * Normal but significant events.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function notice($message, array $context = array());
  /**
   * Interesting events.
   *
   * Example: User logs in, SQL logs.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function info($message, array $context = array());
  /**
   * Detailed debug information.
   *
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function debug($message, array $context = array());
  /**
   * Logs with an arbitrary level.
   *
   * @param mixed $level
   * @param string $message
   * @param array $context
   *
   * @return void
   */
  public function log($level, $message, array $context = array());
}

这是一套日志正常的接口，有层级，有消息，有具体的内容。

LogLevel.php

<"htmlcode">

<"htmlcode">

<"htmlcode">

<"error",$message = "出错啦",$context = "") {
    $this->data([
      'level' => $level,
      'message' => $message,
      'context' => $context,
      'ip' => getIp(),
      'url' => getUrl(),
      'create_on' => date('Y-m-d H:i:s',time())
    ]);
    $this->save();
    return $this->id;
  }
}




一切都准备好了，可以在控制器中使用了！


<"缺少参数id";
    $logger->info("有新消息");
  }
  public function _empty() {
    return "empty";
  }
}





小结：
composer很好很强大！
这里是接口Interface的典型案例，定义接口，定义抽象类，定义具体类。
有了命名空间，可以很好的引用不同文件夹下的库！
互相使用，能够防止高内聚！即便是耦合也相对比较独立！
有了这个日志小工具，平时接口的一些报错信息就能很好的捕捉了！
只要


use Psr\Log\Logger;




然后


$logger = new Logger();
$logger->info("info信息");




使用非常方便！！！
附上获取ip、获取url的方法。


//获取用户真实IP
function getIp() {
  if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
    $ip = getenv("HTTP_CLIENT_IP");
  else
    if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
      $ip = getenv("HTTP_X_FORWARDED_FOR");
    else
      if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
        $ip = getenv("REMOTE_ADDR");
      else
        if (isset ($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
          $ip = $_SERVER['REMOTE_ADDR'];
        else
          $ip = "unknown";
  return ($ip);
}
// 获取url
function getUrl() {
  return 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
}
