You can switch between multiple PHP versions easily by configuring the Nginx virtual host and PHP-FPM. Next, you will need to test which PHP version is used by your Nginx server.
here it is. Apache in itself can't run multiple versions of PHP. So, what we're going to do is update it to use Fast CGI. It has its advantages and disadvantages, but in this case, it's needed.
Setup a new or use old of your php website application on your MAMP htdocs directory ( /Applications/MAMP/htdocs/ ) and setup make sure you already enable vhost to application root directory. Go to your client Browser and test your PHP website. If there is no problem, you already succeed upgrade your MAMP PHP version.
Found a quick fix in the MAMP forums.
Basically it seems MAMP is only allowing 2 versions of PHP to show up. Quick fix, rename the folders you're not bothered about using, for me this meant adding an "X" to my /Applications/MAMP/bin/php/php5.4.10_X folder. Now 5.2.17 and 5.3.20 show up in the mamp prefs.
Done!
Edit - if the PHP version you require isn't in the PHP folder, you can download the version you require from http://www.mamp.info/en/downloads/
Edit - MAMP don't seem to provide links to the alternative PHP versions on the download page any more. Use WayBackMachine https://web.archive.org/web/20180131074715/http://www.mamp.info/en/downloads/
If you need to be able to switch between more than two versions at a time, you can use the following to change the version of PHP manually.
MAMP automatically rewrites the following line in your /Applications/MAMP/conf/apache/httpd.conf file when it restarts based on the settings in preferences. You can comment out this line and add the second one to the end of your file:
# Comment this out just under all the modules loaded
# LoadModule php5_module /Applications/MAMP/bin/php/php5.x.x/modules/libphp5.so
At the bottom of the httpd.conf file, you'll see where additional configurations are loaded from the extra folder. Add this to the bottom of the httpd.conf file
# PHP Version Change
Include /Applications/MAMP/conf/apache/extra/httpd-php.conf
Then create a new file here: /Applications/MAMP/conf/apache/extra/httpd-php.conf
# Uncomment the version of PHP you want to run with MAMP
# LoadModule php5_module /Applications/MAMP/bin/php/php5.2.17/modules/libphp5.so
# LoadModule php5_module /Applications/MAMP/bin/php/php5.3.27/modules/libphp5.so
# LoadModule php5_module /Applications/MAMP/bin/php/php5.4.19/modules/libphp5.so
LoadModule php5_module /Applications/MAMP/bin/php/php5.5.3/modules/libphp5.so
After you have this setup, just uncomment the version of PHP you want to use and restart the servers!
First stop the Server if its running. Go to "/Applications/MAMP/bin/", rename the PHP Version you don't need (MAMP is only allowed to use 2 PHP Versions), e.g. "_php5.2.17". Now MAMP will use the php versions that are left. Go to the MAMP Manager and then settings, then switch to the php version you need.
One problem with this solution I encountered was the httpd process (took me a while to figure that out xD). If you have the httpd process running in the background, then the php switch won't work, until you stop those processes (sometimes MAMP has an awkward problem to stop the server, thats why this process can be still alive). Start your Activity Monitor on your Mac (Shortcut: Press Command+Space and type in activity...), go to the Search Function and type in "httpd", close all those processes. Now you should be able to switch your PHP Version with the MAMP Manager.
Maybe easy like this?
Compiled binaries of the PHP interpreter can be found at http://www.mamp.info/en/ downloads/index.html . Drop this downloaded folder into your /Applications/MAMP/bin/php! directory. Close and re-open your MAMP PRO application. Your new PHP version should now appear in the PHP drop down menu. MAMP PRO will only support PHP versions from the downloads page.
MAMP takes only two highest versions of the PHP in the following folder /Application/MAMP/bin/php
As you can see here highest versions are 7.0.10 and 5.6.25
Now 7.0.10 version is removed and as you can see highest two versions are 5.6.25 and 5.5.38 as shown in preferences
I'm using the free version of MAMP on mac (27 of April of 2021, MAMP version 6.3) and the @LiveSource answer helped me to find a solution.
My MAMP is not showing more than 2 option on the dropdown and on the /Applications/MAMP/bin/php
has 7 options of PHP version. So the MAMP will display the latest 2.
To solve it I changed the name of all PHP version folders that I would not like to use. This way only 2 folders will be compatible with MAMP and my desired versions will display on the dropdown.
I added a _X
in the end but you can add anything.
After doing the change, close the MAMP and open it again.
See the screenshots of the solution working.
