Notice that the fourth parameter of array_slice will only work in PHP 5, and
not for string keys.
There's no associative array slicing function that I know of (it would be a
good idea for PHP to incorporate one), so I use the following two, which
work for numeric or string keys, and work for PHP 4 or 5.
function xarray_slice_assoc($array, $keys) {
/* TODO: Error Handling */
$result = array();
foreach ($keys as $key):
// You can use array_key_exists instead of isset to allow for NULLs and
avoid PHP Notices
if (isset($array[$key])):
$result[$key] = $array[$key];
endif;
endforeach;
return $result;
}
function xslice_assoc() {
/* TODO: Error Handling */
$args = func_get_args();
$array = array_shift($args);
return xarray_slice_assoc($array, $args);
}
You can call them like this:
$userLogin = xslice_assoc($_REQUEST, 'user', 'password');
// $userLogin is now an array with "user" and "password" fields, or only
"user", or only "password" or an empty array
$someRecords = xarray_slice_assoc($someRecordset, array(1, 25, 32, 4));
// $someRecors will contain records number 1, 25, 32 and 41 if they exist
