Bug description: Big numbers add problem
Problem find by [EMAIL PROTECTED]
When run this script everything goes fine until we reach number
2147483647. In php 4.0.4, it turns the number negative. In latest CVS, it
stop add value to the number.
There is the script! To recriate the problem, put the 2147483640 value in
stats.txt and refresh the page many times. The number do not pass
2147483648.
Here's the script.
<?
$counter_file = "stats.txt";
$fp = fopen($counter_file, "r");
$counter = (int)fread($fp, 24);
$close = fclose($fp);
if (!isset($hits)) {
$counter++;
setcookie("hits","1");
} else {
$counter++;
setcookie("hits","$counter");
}
$fp = fopen($counter_file , "w");
fwrite($fp, $counter);
fclose($fp);
print "Number: $counter";
?>
