Let's start by saying that this is not a home counter, although the principle is the same as it is.
One: Prepare a count file, store the link URL and the number of visits, the format is as follows
Id|url|count
ID is the index number to find, URL is the address of the actual file, count is the number of times
Instance data:
Doc01|docs/doc01.html|10
Doc02|docs/doc02.html|10
Two: Prepare the count.php file, the code is as follows:
<?php
Function: Pass in the parameter ID, find the corresponding URL in the Count file, increment the count, and return the actual link
$countfile = "Count.txt";
$lines =file ($countfile);//Read the contents of the count file into the array $lines
for ($i =0; $i <count ($lines); $i + +)
{
List ($sid, $url, $count) =explode ("|", $lines [$i]);
The decomposition string is $id, $url, $count
if ($sid = = $id)//find the specified ID
{
$count +=1; Increase Count
$lines [$i]= $sid. "|" . $url. "|" . "$count". "\ n";//Regenerate Count string
Break
}
}
Write count information
$FP =fopen ($countfile, "w");
for ($i =0; $i <count ($lines); $i + +)
Fputs ($fp, $lines [$i]);
Fclose ($FP);
Header ("Location: $url");
?>
Note: This is the incomplete version on the phpuser.com, I added some changes, it should be able to use now.
Third: The hyperlink in the home page should be called to:
<a href= "COUNT.PHP?ID=DOC01" >doc01</a>
Program features are:
First read the contents of the count file into the array
Then look for the specified ID number from the array, such as find the true link to the $url file, and then add the count to 1,
Regenerate count information
Write count information to the file
Back to link
Four: The number of visitors quoted is the following sentences, write a function can also, I stole the lazy,
Who wrote it, give me a:)
<?php
$countfile = "Count.txt";
$lines =file ($countfile);
List ($sid, $url, $count) = Explode ("|", $lines [0]);//$lines [0] corresponds to Count.txt
First record
Echo $count;
?>
