Re: [PHP] Mystery foreach error

	I think I figured it out.

<?php
$states = array(
    'AL' => array( '350','351','352','353', ),
    'AK' => array( '995','996','997','998','999', ),
    'AZ' => array( '850','851','852','853','854', ),
    'WI' => array( '530','531','532', ), 
    'WY' => array( '820','821','822','823','824', ),
);

$zip = 35261;
$state = 'XX';

$zip_short = substr($zip, 0, 3);
foreach ($states[$state] as $zip_prefix) { 
    if ($zip_prefix == $zip_short) {
        echo "State = $state";
    } else {
        echo 'no';
    }
}
?>

	Running this script, I got the same error as before.  If $state is a known state abbreviation in the array, everything is fine, but if someone was to enter, say 'XX' like I did above or leave it blank, then the error is produced.  I placed an if statement around the foreach loop to test for that and I'll keep an eye on it.

	Thank you for getting me to look at the array again, which led me to look at the State.
