Let's say that you have 4 versions of PHP installed, and you only want to update the default PHP version, or php1_release. You know that if you do, recompiling all versions of PHP is going to take a while, so you may be deterred to update because of this. In the following example, we have 4 versions of PHP, and only want to update php1_release from version 7.2 to version 7.3:
php1_release 7.2 php2_release 7.1 php3_release 7.0 php4_release 5.6
You can check the PHP versions and handlers installed using the following command:
grep -P 'php[\d]_' /usr/local/directadmin/custombuild/options.conf
You can use php_expert to compile only a single version and save yourself some time.
Use this command like so (provided the PHP version is using PHP-FPM):
cd /usr/local/directadmin/custombuild ./build set php1_release 7.3 ./build update ./build php_expert 7.3 php-fpm ./build rewrite_confs
And viola! Using the php_expert build option is ideal for busy system administrators eager to save time and provide quicker resolutions for their clients.
