You can:
if ( in_array ( $CUST_CITY,array_keys($city_array )) ) echo " FOUND
$CUST_CITY IN ARRAY";
else echo "Not found";
A+

Subject: [PHP-WIN] in_array with an associative array... stuck
I'm attempting to see if a variable exists in an associative array but I've
come up empty after two hours... any help out there?
I've already tried array_search and the psuedo functions inside_array and
array_in_array from the user comments in the documentation but they all
return false for what is an obvious match... I've also tried this with
$CUST_CITY in "'s and out of them (e.g. in_array ( "$CUST_CITY", $city_array
) and in_array ( $CUST_CITY, $city_array ) ) but I don't think I should
need "'s around $CUST_CITY
Pieces of the code that are relevent:
$city_array = array (
'ALEXANDRIA' => '43001'
,'GLENFORD' => '43739'
,'GRANVILLE' => '43023'
);
$CUST_CITY = "GRANVILLE"; //this is actually retrieved from a database in
the real code...
if ( in_array ( $CUST_CITY , $city_array ) ) {
if ( $debug ) { echo "<!-- FOUND $CUST_CITY IN ARRAY -->\n";
}
echo "<option value=\"NOT LISTED\">NOT LISTED</option>\n";
//sift through city array and write city options
foreach ( $city_array as $key => $value) {
echo "<option ";
if ( $CUST_CITY == $key) {
echo "SELECTED";
}
echo "value=\"$key\">$key</option>\n";
}
echo " <input type=\"text\" name=\"ALT_CITY\"
value=\"$CUST_CITY\">";
}
else {
if ( $debug ) { echo "<!-- DID NOT FIND $CUST_CITY IN ARRAY
5-->\n"; }
echo "<option SELECTED value=\"NOT LISTED\">NOT
LISTED</option>\n";
//sift through city array and write city options
foreach ( $city_array as $key => $value) {
echo "<option value=\"$key\">$key</option>\n";
}
echo " <input type=\"text\" name=\"ALT_CITY\"
value=\"$CUST_CITY\">";
}
Thanks in advance.
