Question

基本上,我正在建立一个数字艺术项目。

For this I am aiming to get a webpage to show how many visits its had by displaying an image for every visit. So basically every time someone visits or refreshes the web page a new image will appear; 50 visits = 50 images and so on. I want the images to be taken from a folder on the server at random. I have code for a basic visit counter, but it only works for sessions. I need to edit this code so that for every visit a random image appears. Apparently it should be fairly simple but I am very new to php and am still learning a lot.

这是我为访问反省而制定的守则:

session_start();
if(isset($_SESSION[ views ]))
  $_SESSION[ views ]=$_SESSION[ views ]+1;
else
  $_SESSION[ views ]=1
echo "Page views: ".$_SESSION[ views ];

Any help would be hugely appreciated :) Thanks for your time.

Answer 1

你们需要利用数据库服务器或关键价值储存等解决办法,以某种方式坚持服务器上的访问次数。例如,可在服务器上安装,然后在服务器上安装一个用户,如 Predis 。

$redis = new PredisClient();
$redis->incr( views );

那么,如果你想要知道你有多少看法,你可以使用:

$views = $redis->get( views );

Answer 2

a. 使用txt文档储存该数字:

<?php $pageCount = ("count.txt");
$number = file($pageCount);
$number[0] ++; 
$open = fopen($pageCount,"w");
fputs($open ,"$number[0]"); 
fclose($open); echo $number[0]; ?>

Now, all the visits are added to the count.txt you can now add the second part to open the number of images. I am on my phone, so I am unable to test the next part done, but this link might help: http://chrisvall.com/coding/php-how-to-get-a-random-image-to-display-from-a-specific-folder Now, the next part would use $number as the number and do a for loop until all the images are echoed onto the page. I hope this helps
