php7.1: fix non-numeric value encounted warning

Some swivels can return empty string, and we can't perform bitwise & on
non-numeric values on 7.1 without getting a warning.

php 7.1 (adding cast eliminates the warning):
```
$ php --version
PHP 7.1.8-2+ubuntu16.04.1+deb.sury.org+4 (cli) (built: Aug  4 2017 13:04:12) ( NTS )

$ php -r 'var_dump("" & 0);'
PHP Warning:  A non-numeric value encountered in Command line code on line 1
int(0)
$ php -r 'var_dump((int)"" & 0);'
int(0)
```

php 5.6 (doesn't require the cast):
```
$ php --version

$ php -r 'var_dump("" & 0);'
int(0)
$ php -r 'var_dump((int)"" & 0);'
int(0)
```
