Question

所以，我试图显示时间戳，但我真的不知道该怎么做。顺便说一下时间戳的介绍会很棒，我真的不知道它是什么，它做了什么。在初学者的水平上解释它。

时间戳应为秒。第一条记录的时间戳始终为0，因为它表示饮酒会话的开始。

基本上，我想要的是会有一个按钮＆＃34; +＆＃34;这将自动显示时间戳......

用户添加摄入量的时间戳。时间戳是用户点击“+”按钮记录摄入量的时间。

注意：我希望它只能在php中完成..我不会要求代码只是指出我如何实现我想要的正确方向..谢谢！

我还在学习自己，但这看起来像一个有趣的小项目，所以我想我会放弃它。您只需要两次更改路径。您可以使用css更改布局。

<?php

$timeNow = time();

//When a button is used, if action is set, than
if(isset($_GET['action'])){

    //When reset button is used redirect to start page
    if($_GET['action'] == 'Reset'){
        header('Location: *path*');  //path to your file, e.g. file.php 
    }

    //get all variables
    $timeDiff = $_GET['timeDiff'];
    $timeStart = $_GET['timeStart'];
    $start = $_GET['start'];

    //Make an array out of this string
    $timeDiffArray = explode(',', $_GET['timeDiff']);

    //iterate through the array
    foreach($timeDiffArray AS $diff){
        echo "Time: " . $diff . "<br>";
    }

    //First beer, do this
    if($start == 'true'){

        //change to false, not first loop anymore
        $start = 'false';

        //set time of Start
        $timeStart = time();

    //2 or more beer, do this   
    }else{

        //Set difference between time first beer and start this beer
        $diff = $timeNow - $timeStart;

        // output last differense
        echo "Time: " . $diff . "<br>";

        //add difference to the timediff string
        $timeDiff .= ',' . $diff;
    }

//Start , if action is not set, than
}else{

    $start = 'true'; //true because its going to be the first loop
    $timeDiff = 0; //first always start with 0
    $timeStart = null;  //declaire $timeStart
    echo 'No time set.';
}

//form 
//path to your file, e.g. file.php 
echo '<form action="*path*"> 
    <input type="hidden" name="start" value="' . $start . '">
    <input type="hidden" name="timeDiff" value="' . $timeDiff . '">
    <input type="hidden" name="timeStart" value="' . $timeStart . '">
    <input type="submit" name="action" value="Reset" />
    <input type="submit" name="action" value="Submit">
    </form>';
?>

使用php的基本时间戳
