Hi, So I got his code below. $year is a string of 2010,2011 etc.
I guess I want to convert $year to an integer so I can do my if statement to see if the year string is greater than 2010? Or how could I do this?
Right now I get a syntax error doing this.

strnatcasecmp
STRNATCASECMP(3) 1 STRNATCASECMP(3) strnatcasecmp - Case insensitive string comparisons using a ";natural order" algorithm SYNOPSIS
int strnatcasecmp (string $str1, string $str2) DESCRIPTION
This function implements a comparison algorithm that orders alphanumeric strings in the way a human being would. The behaviour of this function is similar to strnatcmp(3), except that the comparison is not case sensitive. For more information see: Martin Pool's Natural Order String Comparison page. PARAMETERS
o $str1 - The first string. o $str2 - The second string. RETURN VALUES
Similar to other string comparison functions, this one returns < 0 if $str1 is less than $str2 > 0 if $str1 is greater than $str2, and 0 if they are equal. SEE ALSO
