如何使用PHP中的setInterval函数从数据库获取数据

Question

I want to get data back from my database using setInterval() to do it every 60 seconds. 我想使用setInterval（）从数据库取回数据，每60秒执行一次。 I want to be able to get back 'message' and 'to' from my database. 我希望能够从数据库中获取“消息”和“至”。

my database table 'message': 我的数据库表“ message”：

id,  message,                 to,         from       status
1,   'hello',                'Rebecca',  'Erwin'     1
2,   'see you soon',         'Veronica', 'Erwin'     0
3,   'the party was awsome', 'Erwin',    'Rebecca'   1
4,   'can you make it?',     'Veronica', 'UNKNOWN'   1 



<?php
    $con = mysqli_connect('localhost','user','pass','my_db');
    if (!$con) {
        die('Could not connect: ' . mysqli_error($con));
    }

    $sql="SELECT * FROM mesage where status=1";
    $result = mysqli_query($con,$sql);
?>

 function run_script() { cont_m = 0; cont_s = 0; s = document.getElementById("seconds"); m = document.getElementById("minutes"); window.setInterval( function() { if (cont_s == 60) { cont_s = 0; cont_m++; //get array from database, how do I run the query here get the array and display arrays? m.innerHTML = cont_m; if (cont_m == 60) { cont_m = 0; } } s.innerHTML = cont_s; cont_s++; //}, 1000); every second }, 100);// every 100 miliseconds for example purpose }

 <body onload="run_script()"> <p> <span id="minutes">0</span>:<span id="seconds">0</span> </p> </body>

You are trying to run a timing event on server-side using a client-side js function? 您是否正在尝试使用客户端js函数在服务器端运行计时事件？ I don't think that's a very good idea. 我认为这不是一个好主意。 You should check other ways to do this.What you need is a cron , or something similar. 您应该检查其他方法来执行此操作。您需要的是cron或类似的东西。
