This article shares with you the code to implement the Snake game using php. The main idea is to record the location through the session. It should be said that the idea is very clever and recommended to everyone

The Snake game is a classic mobile game. Simple and playable. By controlling the direction of the snake's head to eat eggs, the snake will grow longer and gain points. In the era of Nokia, it was popular in the entire mobile phone industry. Today we will take a look at the alternative, how to use PHP to implement the Snake game

Without further ado, here is the code:

control.php

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8"/>
  </head>
  <body>
     <a href="control.php?a=up">上<a/>       <?session_start(); echo $_SESSION[&#39;count&#39;];?>分<br/>
    <a href="control.php?a=left">左<a/> <a href="control.php?a=right">右<a/><br/>
     <a href="control.php?a=down">下<a/>
    <?
       
      switch($_GET[&#39;a&#39;]){
        case "up";
          $_SESSION[&#39;con&#39;]="up";
        break;
        case "down":
          $_SESSION[&#39;con&#39;]="down";
        break;
        case "left":
          $_SESSION[&#39;con&#39;]="left";
        break;
        case "right":
          $_SESSION[&#39;con&#39;]="right";
        break;
      }
    ?>
  </body>
</html>

main .php

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-9"/>
    <meta http-equiv="refresh" content="0.5"/>
  </head>
  <frameset rows="95,*" border="1" noresize >
