Use the counter code directly in the php file:
$countfile = "num.txt";
//The file written by the definition counter is num.txt in the current directory, and then we should test whether the file can be opened
if (($fp = fopen($countfile, "r+")) == false) { //Open the file in read-write mode, exit if it cannot be opened
printf ("Failed to open file %s!",$countfile);
exit;
}
else
{
//If the file can be opened normally, read the data in the file, assuming it is 1
$count = fread ($fp,10);
//Read 10-bit data
$count = $count + 1;
fclose ($fp);
//Close the current file
$fp = fopen($countfile, "w+");
//Open the file in overwrite mode
fwrite ($fp,$count);
//Write new data plus 1
fclose ($fp);
//And close the file
echo 'Hello, you are the '.$count.' visitor';
//Output data
}
?>
Just save the above content into php and create num.txt in the same directory
But we often see that the statistical codes of many websites are displayed in the form of js calls. Let’s briefly modify it:
$countfile = "num.txt";
//The file written by the definition counter is num.txt in the current directory, and then we should test whether the file can be opened
if (($fp = fopen($countfile, "r+")) == false) { //Open the file in read-write mode, exit if it cannot be opened
printf ("Failed to open file %s!",$countfile);
exit;
}
else
{
//If the file can be opened normally, read the data in the file, assuming it is 1
$count = fread ($fp,10);
//Read 10-bit data
$count = $count + 1;
fclose ($fp);
//Close the current file
$fp = fopen($countfile, "w+");
//Open the file in overwrite mode
fwrite ($fp,$count);
//Write new data plus 1
fclose ($fp);
//And close the file
echo 'document.write("'.$count.'")';
//Output data in javascript form
}
?>
Save the above content to FileCount.php, and create num.txt in the same directory.
In the html file, js calls the method.
