/**
 * Validate form data according to a set of rules. This function can also be
 * used to validate arbitrary data, not just form data. Nested data and rules
 * are also supported, as well as array data. Rules can either be a regular
 * expression pattern, an integer filter for `filter_var()`, or a `Closure`
 * object. If the data is not found, then the value to be tested is null.
 *
 * Example:
 *
 * $data = array(
 *     'name' => 'John Doe',
 *     'age'  => 30,
 * );
 *
 * $rule = array(
 *     'name' => 'required',
 *     'age'  => 'digits',
 * );
 *
 * $valid = form_validate($data, $rule, $errors);
 *
 * if ($valid) {
 *     // data is valid, do what you must do.
 * }
 *
 * The variable $valid will evaluates to `true` while $errors will have the
 * following structure:
 *
 * array(
 *     'name' => false,
 *     'age'  => false
 * )
 *
 * The $errors variable contains error flags. `true` means the input does not
 * conform to the rule while `false` means the input *does* conform to the rule.
 *
 * Although it may seem backwards (i.e., false means OK), this structure gives
 * us the convenience of outputting error messages in our templates, using plain
 * PHP, as follows:
 *
 * <?php if $errors['name'] ?>
 * <p>The name field is required.</p>
 * <?php endif ?>
 *
 * The above rules 'required' and 'integer' are builtin shortcuts to the string
 * '/^.+$/' and '/^\d+$/' respectively.
 *
 * @param array $data   Set of key-value data to be validated
 * @param array $rules  Set of key-value rules
 * @param array $errors Set of returned error flags (optional)
 *
 * @return bool Boolean true if the data is valid, false otherwise
