Random number in range [min - max] using PHP

Question

Is there a way to generate a random number based on a min and max?

For example, if min was 1 and max 20 it should generate any number between 1 and 20, including 1 and 20?

Answer 1

Try This one. It will generate id according to your wish.

function id()
{
 // add limit
$id_length = 20;

// add any character / digit
$alfa = "abcdefghijklmnopqrstuvwxyz1234567890";
$token = "";
for($i = 1; $i < $id_length; $i ++) {

  // generate randomly within given character/digits
  @$token .= $alfa[rand(1, strlen($alfa))];

}    
return $token;
}
