How to use for loop to write to file?

[deko]

This has got to be an easy question - for some reason I can't seem to get
this to work. Is there a better way? All I want is a quick and dirty way
to populate a file with UNIX time stamps...

<?php
//viscount_helper.php
$vc = 'viscounter_test.txt';
$avdaily = 5; average daily
$total_count = (365 * $avdaily); //time period = one year
echo $total_count;
$interval = (86400)/$avdaily; //evenly spaced intervals
echo $interval;
$visit = time() - (31536000);
echo $visit;
//$next_time = ($first_time + $interval)
$fp = fopen($vc,"a");
for($i = 1; $i > $total_count; $i++)
{
fwrite($fp, $visit."\n");
$visit = $visit + ($interval * $i);
}
fclose($fp);

Are you sure this should be > rather than < ?

Unless average daily is ever 0, the loop will never run =)

{
fwrite($fp, $visit."\n");
$visit = $visit + ($interval * $i);
}
fclose($fp);

Other than that, I'd say it's pretty much the "only" way =)

Good catch - that was part of it...

Here's a working version:

$vc = 'countfile.txt';
$avdaily = 38; //expected average daily hits
$total_count = (366 * $avdaily);
echo "<br>total_count = ".$total_count;
$interval = (86400 / $avdaily); //evenly spaced intervals
echo "<br>interval = ".$interval;
$visit = (time() - (31622400));
echo "<br>first visit = ".$visit."<br><br>";
$fp = fopen($vc,"w");
for($i = 1; $i <= $total_count; $i++)
{
echo $visit."<br>";
fwrite($fp, $visit."\n");
$visit = ($visit + $interval);
}
echo "<br>last visit = ".$visit;
fclose($fp);

The problem is that I am getting decimal output in $visit - e.g.
1058691603.37
Is there a way to force an integer value to avoid decimals?
