Upgrading PHP from 7.0.22 to 7.1.9

I created a shell script which began its simple life as

#!/bin/sh

# Use on first run
FLAGS=-ncfpvo

# Use on subsequent runs
#FLAGS=-fpvo

portupgrade ${FLAGS} lang/php71 lang/php70 || exit

portupgrade ${FLAGS} textproc/php71-ctype      textproc/php70-ctype      || exit
portupgrade ${FLAGS} ftp/php71-curl            ftp/php70-curl            || exit
portupgrade ${FLAGS} textproc/php71-dom        textproc/php70-dom        || exit

portupgrade ${FLAGS} converters/php71-iconv    converters/php70-iconv    || exit
portupgrade ${FLAGS} devel/php71-json          devel/php70-json          || exit
portupgrade ${FLAGS} net/php71-ldap            net/php70-ldap            || exit
portupgrade ${FLAGS} converters/php71-mbstring converters/php70-mbstring || exit
portupgrade ${FLAGS} security/php71-mcrypt     security/php70-mcrypt     || exit

portupgrade ${FLAGS} archivers/php71-zlib      archivers/php70-zlib      || exit

portupgrade ${FLAGS} www/mod_php71 www/mod_php70 || exit

After running the script for a second time and a third time, etc, the script was successively changed to:

#!/bin/sh

# Use on first run
#FLAGS=-ncfpvo

# Use on subsequent runs
FLAGS=-fpvo

#portupgrade ${FLAGS} lang/php71 lang/php70 || exit

#portupgrade ${FLAGS} textproc/php71-ctype      textproc/php70-ctype      || exit

portupgrade ${FLAGS} textproc/php71-xml        textproc/php70-xml        || exit
portupgrade ${FLAGS} textproc/php71-wddx       textproc/php70-wddx       || exit

portupgrade ${FLAGS} www/mod_php71 www/mod_php70 || exit

Restart Apache using service apache24 restart.

In the end, PHP 7.0.22 got upgraded to PHP 7.1.9. All is well.
