About the configuration and use of PHP log LOG4PHP

This article introduces you to the configuration and use of PHP log LOG4PHP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

I maintain an old project without a logging function, so I added log4php. The main reason is that it is easy to integrate and it is sufficient to use.

1. Download log4php

2. Create configuration file

log4php_config.xml

<configuration xmlns="http://logging.apache.org/log4php/">
    <appender name="default" class="LoggerAppenderConsole" />

    <appender name="basic_file_appender" class="LoggerAppenderDailyFile">

require_once(&#39;vendor/log4php/Logger.php&#39;);
Logger::configure(&#39;vendor/log4php/log4php_config.xml&#39;); // 引入第二步创建的xml配置文件

class L
{
    public static function __callStatic($name, $args)
    {
        $log = Logger::getLogger(&#39;app&#39;);

        switch ($name)
        {
            case &#39;error&#39;:
                $log->error($args);
                break;
            case &#39;info&#39;:
                $log->info($args);
                break;
            case &#39;warn&#39;:
                $log->warn($args);
                break;
