OSX Yosemite comes with PHP 5.5. OSX Mountain Lion comes with PHP 5.3. What if you wanted to run PHP 5.4 on both? Well, you can, with a dead simple installation;
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.4

Still not seeing the new version?
- The command above should install the old PHP 5 in /usr/local/php5 (which should be user-writable) and also write a new config file in /etc/apache2/other/+php-osx.conf, so please check and see if both exist.
If you installed PHP 7.x, the folder is /usr/local/php7, of course.
apachectl -t -D DUMP_INCLUDESand check if the new config file is loaded (should be /etc/apache2/other/+php-osx.conf)
apachectl configtestand see if any errors occurred
If you can’t get it to work, try alternate methods, like using the even older series of posts on How to set-up and maintain a development environment on osx, OR (even better!) use Local by Flywheel.
