How PHP uses text statistics to access _php tips

This example describes how PHP uses text statistics to access the volume. Share to everyone for your reference, specific as follows:

Method 1:

$fp = fopen ("Counter.txt", "r+");
while (!flock ($FP, LOCK_EX)) {//acquire a exclusive lock
  //Waiting to lock the file
}
$counter = Intval (fre AD ($fp, FileSize ("Counter.txt"));
$counter + +;
Ftruncate ($fp, 0);   Truncate file
fwrite ($fp, $counter);//Set your data
fflush ($FP);      Flush output before releasing the lock
flock ($fp, lock_un);  Release the lock
fclose ($FP);

Method 2:

counter.php file:

<?php
/* Counter
///opens countlog.txt to read the number
of hits $datei = fopen ("Countlog.txt", "R"); 
    $count = fgets ($datei, 1000);
Fclose ($datei);
$count = $count + 1;
echo "$count";
echo "hits";
echo "\ n";
Opens Countlog.txt to change new hit number
$datei = fopen ("Countlog.txt", "w");
Fwrite ($datei, $count);
Fclose ($datei);
? >

Usage:

<?php
include ("counter.php");
? >
