I am running a site on EE 3.5.17 and I am trying to determine which version of PHP I can use without causing issue or conflicts with existing plugins, which includes CartThrob 3.2. The EE documentation says the following is required for EE 3.x:

PHP 5.3.10 can also be read as five-point-three-point-ten. That means 5.3.10 is greater than 5.3.1, 5.3.2, 5.3.3, and all the way up to 5.3.9.

I am currently running PHP 5.4 for the site but would like to move to 5.6.4 or greater given the EOL issues.

I would appreciate perspective from the community. Thanks.

The short answer is yes. The documentation indicates that the minimum version is 5.3.10 but EE3 will work with php versions up to 7.2 depending upon which EE3 you install: php 7 compatability was included in EE3.1 HTH
