Question

I am trying to match numbers within an array with a range of numbers, i have been told to use preg_match. Unfortunately I am not good at regular expressions. Any suggestions?

<?php

$range = range(89000000,89499999);
foreach($range as $number)
{

     if (preg_match("/89304043/", $number))
     {
      die( "Valid carrier Number" );
     }
     else
     {
       die( "Invalid carrier Number" );
     }


}
?>

Answer 1

$number=(int)$number;
$valid=($number>=89000000 && $number<=89499999);

$valid is now either true or false. I typecast the number to ensure it’s an integer (And I presumed that there were no non-numeric characters in it.
