Some fresh benchmarks over the past day on PHP 5.5.38, PHP 5.6.38, PHP 7.0.32, PHP 7.1.24, PHP 7.2.13, and the PHP 7.3.0 release. PHP 7.3 is just shy of 10% faster than PHP 7.2 in the popular PHPBench. PHP 7.3 is 31% faster than PHP 7.0 or nearly 3x the speed of PHP5.

Helpful quick todo for freebsd 12.0 to upgrade used PHP from 7.2 to 7.3:

a) put into /etc/make.conf line containing „DEFAULT_VERSIONS += PHP=7.3“

b) use some quick script to generate two useful commands to made the upgrade:

!/usr/local/bin/bash
LIST_DEL=““
LIST_INS=““
for FILE in pkg info | grep php72 | cut -f1 -d' ' ; do
PKGNAME=pkg info "$FILE"|grep 'Origin'|cut -f2 -d':' ;
NEWPKGNAME=“${PKGNAME//php72/php73}“ ;
LIST_DEL=“$LIST_DEL $FILE“;
LIST_INS=“$LIST_INS $NEWPKGNAME“;
done
echo „pkg delete -f $LIST_DEL“;
echo „portmaster $LIST_INS“;
