How to delete from an array.
Answer to [oseibert at haba-ag dot de].
Unset() completly deletes an entry from the array. If you want the array numeric keys follow in a
natural order you can use array_values() also.
function deleteKey($array, $keyname, $value)
{
end($array);
$last = key($array);
for($i=0; $i<=$last; $i++)
{
if($array[$i][$keyname] == $value)
{
unset($array[$i]);
}
}
$newArray = array_values( $array );
return $newArray;
}
