File-based PHP counter
// PHP counter, based on the file system.
Function WinCOUNTER () {
// If the file does not exist, create it
IF (! File_exists ("count.txt")))
{
EXEC ("echo 0> count.txt");
}
/ / Open our record file
// Get the file size then takes out the required data according to the size of this file.
$ fp = fopen ("count.txt", "r );
$ Filesize = filesize ("count.txt");
$ Count = fgets ($ FP, $ FILESIZE 1);
// Plus the number of records to 1 in the file back
$ Count = 1;
FSeek ($ FP, $ COUNT);
Fclose ($ fp);
/ / Return to the current number of visit
RETURN $ COUNT;

Based on the database's counter (mysql)?
1. First create a database:
Create Table Counter {
Counter int not null,
ID INT NOT NULL
}
Insert Into Counter (Counter, ID) Values (0, 1)
2, counter code:
// PHP counter, based on the MySQL database server.
Function Linuxcounter () {
/ / Connect MySQL Database
$ conn = mysql_connect ("LocalHost", PHPBOOK "," ")
// Query the current browse number
/ / Pay attention to the way
$ SQL = "SELECT * from counter";
$ Result = mysql_query ($ SQL, $ conn);
$ objresult = mysql_fetch_Object ($ results);
$ count = $ objresult-> counter;
/ / Update the database and return to the current browse number as a result
$ SQL = "Update Counter Set Counter =". ($ Cont 1). "Where id = 1";
MySQL_Query ($ SQL, $ conn);
MySQL_Close ($ conn);
Return $ COUNT 1;
}
