Change PHP version on server using either .htaccess or php.ini

问题

How can I change the PHP version to 5.2 on a server using either an .htaccess of php.ini file?

回答1:

Adding

AddHandler application/x-httpd-php52 .php .php5 .php4 .php3

to your .htaccess might work.

回答2:

I take it you want to process e.g. .php3 files with php 3.x.

You can't switch between php versions like this, but you might be able to do it by setting up a proxy server that distributes the query to one of several servers (one for each PHP version).

There might also be some apache hack that works by calling the cgi-bin mode php in FastCGI mode. See the linked answer for this.

According to https://www.first2host.co.uk/f/change-php-version-php-ini/, adding the following line to your php.ini file will change you to PHP version 5.2:

AddHandler application/x-httpd-php52 .php

It only works if your host is first2host though, I reckon.
