Anyone else have this experience? I generally don't have to typecast
before a comparison, but in_array seems to require it?
#! /usr/bin/php -q
<?php
//Test Data
$primary_phone = '18017848218';
// Load the zip code information
$file_handle = fopen('./area_codes', 'r');
$area_codes = array();
while (!feof($file_handle)) {
$area_codes[] = fgets($file_handle);
}
$area_code = substr($primary_phone, 1, 3);
//Doesnt Work
if (!in_array($area_code, $area_codes, FALSE)) {
$error_message = 'PLEASE ENTER A VALID PHONE NUMBER!';
$commit = 0;
}
//Works
if (!in_array((int)$area_code, $area_codes, FALSE)) {
$error_message = 'PLEASE ENTER A VALID PHONE NUMBER!';
$commit = 0;
}
echo $error_message;
?>
