I assume you have just added the '*' first in the line to show which 
rows you are talking about.

Simple maths will show your error, lets count your opening parentheses

if (ctype_alnum(str_split($zip,1)) {
    1           2         3

and now the number of closing parentheses

if (ctype_alnum(str_split($zip,1)) {
                                 12

So we get 3 opening parenthesis and 2 closing, this is what the "Parse 
error: syntax error, unexpected '{'" is about, you need to close all 
your parentheses.


You know you will end up with loads of if cases if you keep on doing 
this instead of using a regular expression, this would speed it up and 
make your code a lot easier to read (case insensitive):


if(preg_match("/^[a-z]\d[a-z] \d[a-z]\d$/i",$postcode)) {
         // this could be a valid Canadian postcode
	// just add what you need to do to check it against
	// Canadian Post, worst case use the "Find a post office"
}
