This is a snippet that creates a dynamic dropdown menu with countries. The select is created from the $countries array. You can set a country that will be selected automatically when the drop down is loaded. This can be done by editing the variable $default. You can specify the key from the array (i.e.: 220 for US) or the country name (i.e.: Argentina).

Hello coders,

We know that arrray_search() is a function used to search the array for given value and return the corresponding key. This works fine in a case sensitive mode, but in an insensitive one we have a problem. If we search for ‘blue’ and there is a value in array ‘BLUE’, our array_search() will return NULL. Here’s a function that works like array_search() & ignores the sensitive case:

<?php
function array_isearch($value, $array)
{
   while (list($key, $val) = each($array))
   {
      $val = strtolower($val);
	  $value = strtolower($value);

      if($val == $value) return $key;
   }
return false;
}
?>

Usage Example:

<?php
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key_one = array_isearch('BLUE', $array);

echo 'Key One: '.$key_one;

echo '<br />';

$key_two = array_isearch('GrEeN', $array);

echo 'Key Two: '.$key_two;
?>
