Can anyone figure out what I'm doing wrong?

I'm trying to increase a number based on a timestamp. The number increases each second by adding a random number from 1 to 10.

The number increases and then decreases, but how can I stop it from decreasing?

<?php

\$start_time = 1266967333; //Start time timestamp
\$number_start = 100; //Start value of number
\$random_increase = mt_rand(1,10); //Increments per second

echo floor(\$number_start+(((time()-\$start_time)/1)*\$random_increase));

?>

Thanks!

The number decreases because you run the script with a random number and then run it again with a different random number.

You are not incrementing anything as there is no loop.

echo \$random_increase;

And you'll see that the lower the random the lower the number.. the higher the higher.

This code increments by the same random number 1 times a second for 101 seconds.

<?php

\$start_time = 1266967333; //Start time timestamp
\$number_start = 100; //Start value of number
\$random_increase = mt_rand(1,10); //Increments per second

for (\$x = 1; \$x <=100; \$x++) { //loops until x=101
sleep(1); //pause 1 second
}
?>

Thanks for the help! I tried your example and it still doesn't seem to work.

So I guess it's impossible, since as you mentioned it uses a different number each time?

Using that code on my webserver produces a working result. It looks like this:

166202
166204
166206
166208
166210

If I refresh the page it gets a different random number and gives a different result but increments using that number. Is that what you are looking for?

Yeah, that's exactly what I'm looking for.

Basically, just a way to increment the number by adding a random number from 1-10.

For example:

166202
166207
166208
166210
166218

It always increases (the reason I'm using a timestamp), but randomly increases without following any particular pattern.

Try this:

<?php
\$number = 100; //sets minimum first number
for (\$y = 0; \$y <= 100; \$y++) { //loops until \$y = 101
\$z = mt_rand(1,10); //generate a random nuber between 1 and 10
\$number = \$number + \$z; //add the last number displayed to the random number
echo \$number . "<br />"; // print number to screen
}
?>
