Hi all,

I'm still working on the postal code issue, for Canada at the moment and
I'm still stuck.

I've decided to try:
= See if it's alpha-numeric
= Create an array
= See if there is a space where it belongs
= Validate for digits in proper positions
= Since it's alpha-numeric, the 3 characters left must be Alphabetic.
If the validations work, keep going.
If not, halt & allow for a re-entry.

The ctype statement will NOT work in any form and throws various errors
regardless of wher I place it or what I use s the var. Remove the entire
ctype, and everything works again.

In code, this equates to, as best as I can:
--------------------------------------------------------------------------- ------------------------
IF(strlen($zip) === 7) {
echo "Zip appears to be Canadian . <br />";
}
// ================== NOW LOOK TO SEE IF IT'S ALPHA-NUMERIC

* if (ctype_alnum(str_split($zip,1)) { <---- Throws error [1]
* echo "Is Alpha Numeric.";
*}

// ================ LET'S ASSIGN IT TO AN ARRAY
echo ' <pre>';
print_r(str_split($zip,1));
echo '</pre>';

// ================= check space where it belongs
if($zip[3] === " ") {
echo "Space in correct place<br />";
}
--------------------------------------------------------------------------- ----------------------

[1] : Error is:
Parse error: syntax error, unexpected '{' in C:\xampp\htdocs\twa1.php on
line 107
Line 107 is:
echo "Zip appears to be Canadian . <br />";
--------------------------------------------------------------------------- ----------------------
I have tried various forms of the ctype statement, where it's shown here
and lower in the code after the array is generated, and using $zip[0] .
$zip[3]... etc. I simply can not get any form of the ctype statement
working and I have a LOT of sample code I've collected from several
sources, all not quite what I need.
--------------------------------------------------------------------------- ----------------------

If I change the code & location as follows:
IF(strlen($zip) === 7) {
echo "Zip appears to be Canadian . <br />";
}
// ================== NOW LOOK TO SEE IF IT'S ALPHA-NUMERIC

// ================ LET'S ASSIGN IT TO AN ARRAY
echo ' <pre>';
print_r(str_split($zip,1)); <--------------- LINE 114
echo '</pre>';

if (ctype_alnum(($zip[0]))
echo "Is Alpha Numeric.";

// ================= check space where it belongs
if($zip[3] === " ") {
echo "Space in correct place<br />";
}
--------------------------------------------------------------------------- ------------------
It still throws an error as:
Parse error: syntax error, unexpected T_ECHO in C:\xampp\htdocs\twa1.php
on line 114


What the heck am I doing wrong? Any advice appreciated; I can't believe
I can't get ctype to work; it seems so simple!

TIA,

Twayne`
