PHP Implementation Counter Method Summary, PHP counter Summary

The example of PHP implementation counter is described in this paper. Share to everyone for your reference. Specific as follows:

This collection of three PHP counter code, all of them three have a common point is that all do not need a database, but the use of text files to achieve web browsing count.

The first PHP counter code is as follows:
Copy CodeThe code is as follows: <?php
Counter
function Countx ($file = "Count.dat") {
if (file_exists ($file)) {
$FP =fopen ($file, "R");
$numx =fgets ($FP, 10);
Fclose ($FP);
$numx + +;
The above four lines of code can be replaced by an expression: $numx =file_get_contents ($file) +1;
}
else{
$NUMX = 1;}
File_put_contents ($file, $NUMX);//When the file does not exist, this function automatically creates the file, and automatically turns the parameter into a string write.
Echo $numx;
/* The entire function body can be replaced by two expressions: File_exists ($file)? file_put_contents ($file, file_get_contents ($file) +1): File_put_contents ($ File, "1"); ReadFile ($file);
*/
}
Function call
Countx ();
?>
The second PHP counter, the code is as follows:
Copy CodeThe code is as follows: <?php
$counterfile = "Balong.txt";//the file name of the stored value several paths
function Displaycounter ($counterfile) {
$fp = fopen ($counterfile, "RW");
$num = Fgets ($fp, 5);
$num + = 1;
Print "You are the first". " $num "." A guy looking at the Bahan counter ";
EXEC ("Rm-rf $counterfile");
EXEC ("echo $num > $counterfile");
}

if (!file_exists ($counterfile)) {
EXEC ("Echo 0 > $counterfile");
}

Displaycounter ($counterfile);
?>
The third PHP counter code is as follows:
Copy CodeThe code is as follows: <?php
$counterfile = "Www.jb51.net.txt";//the file name of the stored value several paths

function Displaycounter ($counterfile) {
$fp = fopen ($counterfile, "RW");
$num = Fgets ($fp, 5);
$num + = 1;
Print "You are the first". " $num "." A guy looking at the Bahan counter ";
EXEC ("Rm-rf $counterfile");
EXEC ("echo $num > $counterfile");
