Mac upgraded PHP to 5.6, but CLI php -v get 5.3.28?

Question

I have installed MAMP (comes with PHP 5.5) on my machine. And localhost pointed to /Applications/MAMP/htdocs. The problem happened when I was trying to use composer in terminal to install dependencies in htdocs. Composer complained that PHP must be 5.4 or above.

I guess it complained about PHP comes with OSX. So I have upgraded PHP to 5.6 by

curl -s http://php-osx.liip.ch/install.sh | bash -s 5.6

But when I do

$ php -v

I still get

PHP 5.3.28 (cli) (built: Aug 29 2014 18:52:17) 
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies

And Composer is still complaining...

Why is that? And how to fix this?

Answer 1

If you have upgraded using curl, copy & paste the following line of code and press enter.

$ export PATH=/usr/local/php5/bin:$PATH

Now, type

$ php -v

If done correctly, it should show the following

PHP 5.6.23 (cli) (built: Jun 26 2016 13:17:47)

Answer 2

If you installed PHP 5.6 using Homebrew, this works:

Open Terminal, run open -a TextEdit ~/.bash_profile, then paste this in the end of the file:

# Use Home-brewed PHP 5.6 instead of pre-installed version (5.3)
export PATH="$(brew --prefix homebrew/php/php56)/bin:$PATH"

Save the file and restart Terminal.
