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">
        <layout class="LoggerLayoutPattern">
            <param name="conversionPattern" value="%date [%logger] %message%newline" />
        </layout>
        <param name="file" value="log/app.%s.log" /> // log文件夹下  以日期命名的log文件
        <param name="datePattern" value="Y-m-d" />
    </appender>
    <root>
        <level value="debug" />

        <appender_ref ref="InventoryTransaction_file_appender" />
    </logger>

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

    </logger>

</configuration>

3. LOG class

<?php
/**

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;
            case &#39;debug&#39;:
                $log->debug($args);
                break;
            case &#39;fatal&#39;:
                $log->fatal($args);
                break;
            default:
