[SOLVED] Generate from number.

[Ben Phelps]

I need a good method to generate a random number based on a different number. Here is the code i have now, but it doesn't work.

 

<?php
$i = 35648;
if ($i <= 100) {
    $s = rand(100,299);
} else if ($i <= 1000 & > 100) {
    $s = rand(300,399);
}
  else if ($i <= 5000 & > 1001) {
    $s = rand(400,499)
}  
  else if ($i <= 10000 & > 5001) {
    $s = rand(500,749);
}  
  else if ($i <= 15000 & > 10001) {
    $s = rand(750,999);
}
  else if ($i <= 20000 & > 15001) {
    $s = rand(1000,1499);
}
  else if ($i <= 50000 & > 20001) {
    $s = rand(1500,2499);
}
  else if ($i <= 100000 & > 50001) {
    $s = rand(2500,2999);
}
  else if ($i <= 150000 & > 100001) {
    $s = rand(3000,3499);
}
  else if ($i <= 200000 & > 150001) {
    $s = rand(3500,3999);
}
  else if ($i <= 300000 & > 200001) {
    $s = rand(4000,4499);
}
  else if ($i <= 400000 & > 300001) {
    $s = rand(4500,4999);
}
  else if ($i <= 500000 & > 400001) {
    $s = rand(5000,5999)
}
  else if ($i <= 750000 & > 500001) {
    $s = rand(6000,7499)
}
  else if ($i <= 1000000 & > 750001) {
    $s = rand(7500,9999);
}
  else if ($i <= 2000000 & > 1000001) {
    $s = rand(10000,14999);
}
  else if ($i <= 5000000 & > 2000001) {
    $s = rand(15000,17499);	
}
  else if ($i <= 10000000 & > 5000001) {
    $s = rand(17500,19999);
}
  else if ($i <= 50000000 & > 10000001) {
    $s = rand(20000,19999);
}
  else if ($i <= 100000000 & > 50000001) {
    $s = rand(25000,29999);
}
  else($i >= 100000001) {
    $s = rand(30000,39999);
}
echo $s;
?>

Lots of lines 

 

} else if ($i <= 1000 & $i > 100) {

It was so simple, thank you so much.
