Using Php to implement link popularity statistics_PHP tutorial

First of all, let me explain: This is not a homepage counter, although the principle is the same.
1: Prepare a count file to store the URL of the link and the number of visits. The format is as follows:                                  ​​​​
id is the index number used to search, url is the address of the actual file, and count is Number of times
Instance data: doc01.html|10                                               ​​​?php                                                                                                          
$countfile="count.txt";                                      $countfile);//Read the contents of the count file into the array $lines                                                                                                      🎜>{                                                                                                        $url, $count)=explode("|", $lines[$i]);// Decompose the string into $id, $url, $count                                                                                                                                                                                                                                                                                   $lines[$i]=$sid . "|" . $url . "|" . "$count" . "n";//Regenerate the count string                                                                                                                                 🎜>}                                                                                
//写入计数信息                                                                   
$fp=fopen($countfile, "w");                                                      
for($i=0;$ifputs($fp, $lines[$i]);                                                          
fclose($fp);                                                                     
Header("Location: $url");                                                        
?>                                                                               
注：这个是phpuser.com上的不完全版本，我加了一些改动，现在应该是能用的。

Three: The calling method of the hyperlink on the homepage should be changed to:                                    The program functions are:
First read the content of the counting file into the array                                                                                                                                                                                                                                                      
Write the counting information into the file
Return to the link

Four: The number of visitors is the following sentences. It is also possible to write a function. Give me one :)                                                                                                                                                                                                                                                      ) = explode("|",$lines[0]);//$lines[0] corresponds to count.txt
                                                                                                                                                                                                       🎜>
