Ubuntu 18.04 ships with PHP 7.2 as default PHP version. Major PHP versions are not 100% compatible with each other, so a website might require a newer or older PHP version to work. ISPConfig supports it to use multiple PHP versions on the same server, the PHP version can be selected for each website individually in the website settings. This tutorial shows how to install PHP 7.4 as FPM and FCGI mode alongside PHP 7.2 on a Ubuntu 18 server. The additional PHP versions are installed in the /opt folder, so their installation does nit affect the default PHP versionif(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'howtoforge_com-box-3','ezslot_11',106,'0','0']);__ez_fad_position('div-gpt-ad-howtoforge_com-box-3-0');1 Preliminary NoteI will install PHP 7.4.

I was almost half way through it doing it by myself but I was too insecure to do this on production machines. So I decided to setup a test environment. And then I noticed this now post so I tried it without even reading up on it first. Worked like charm!! I'm confident enough now to also set up php 7.4 on some production machines.As always, great job!! Keep up the good work! By: corto Reply hello, and thx for the tutorial.do it work on debian 9?By: why Reply Please dont advocate this advice. Debsury already has PHP 7.4 packaged.As soon as you hack out the frame work of using a repo, all bets are off. Thats for security and quality of package building. Please see
By: svenner Reply thanks great work...is there a guide for php 7.4 on centos 7 with ispconfig, or anyone else try this guide on a centos machine ? By: Matteo Busolin Reply Thanks for the tutorial. I suggest to add another (optional) section after the point 3.2 to install imagick module for php-fpm (very useful if you need to host new wordpress websites). I achived this following these steps:
