This article mainly introduces the method of using PHP text counter to realize the function of statistical website visits.

Website visits is one of the important factors for observing website traffic. So how do we use PHP to count website visits?

In fact, as long as everyone masters the idea of implementation, it will be very easy to understand.

That is, when the user issues an access request to the server, the server reads the file with the number of accesses. If the file does not exist, it is created. If the file exists, it is 1, and then returns to the client, and the server saves it. The same goes for the number of new views and the new user access process.

We have this idea in this article [How does PHP continuously write content to the file header? ], it has also been introduced in detail for everyone, you can choose to refer to it.

Below we will give you a detailed introduction to the implementation method of Text Counter based on specific code examples.

<html>
<head>

    <title>PHP网站访问量文本计数器</title>
</head>
<body>
<?php
$fileName = &#39;hello.txt&#39;;
$max= 9;
if (!is_file($fileName)) {
    touch(&#39;hello.txt&#39;);
    $file = fopen($fileName, &#39;rb+&#39;);
    fwrite($file, 1);
    fclose($file);
    return ;
} else {
    $file = fopen($fileName, &#39;r&#39;);
    $content = fread($file,$max);
    fclose($file);
    $file = fopen($fileName, &#39;w&#39;);
    $content++;
    fwrite($file, $content);
    fclose($file);
}
    ?>
<div id="dd" align="center">

</div>
</body>
</html>

In the above code, the calculation method for implementing text counter is written for everyone.

Here we define a 'hello.txt' data file. First determine whether the file exists. If it does not exist, create it and use 1 as the initial data. Otherwise, read the data, close the file, and then accumulate the The data is written to 'hello.txt' to accumulate data, and finally the data information is output to the web page.
