Multiple selection in a single table using php mysql

Question

I'm trying to pull multiple rows from a single table. I'm trying to pull either all males or all females in different zip codes.

<?php
$zipCodes = array("55555", "66666", "77777", etc...);

$fetchUser = mysql_query("select * from users where gender = '$_POST[gender]' ".implode(" or zipCode = ", $zipCodes)." order by id desc");
while($var = mysql_fetch_array($fetchUser)) {
  code...
}
?>

I think you forgot to ask a question. What's the problem with your code? — Mahmoud Gamal

You should use IN on this,

SELECT ...
FROM   tableName
WHERE gender = '$_POST[gender]' AND
      zipCode IN (55555, 6666, 77777)

currently your code is vulnerable to SQL Injection. Please read on PDO or MySQLI extension.

// Prevent SQL injection for user input
$fetchUser = mysql_query("select * from users where gender = '".filter_var($_POST[gender], FILTER_SANITIZE_STRING)."' OR zipCode IN (".implode(",", $zipCodes).") order by id desc");)
