Change default Mac OS X PHP to MAMP's PHP Installation

Instructions to Change PHP Installation

First, Lets find out what version of PHP we're running (To find out if it's the default version).

To do that, Within the terminal, Fire this command:

which php
This should output the path to the default PHP install which comes preinstalled by Mac OS X, by default it has to be (Assuming you've not changed it before):

/usr/bin/php
Now, We just need to swap this over to the PHP that is installed with MAMP, which is located at /Applications/MAMP/bin/php/php5.4.10/bin (MAMP 2.1.3)

To do this, We need to edit the .bash_profile and add the MAMP version of PHP to the PATH variable.

Follow these simple steps:

Within the Terminal, run vim ~/.bash_profile

Type i and then paste the following at the top of the file:

export PATH=/Applications/MAMP/bin/php/php5.4.10/bin:$PATH
Hit ESC, Type :wq, and hit Enter

In Terminal, run source ~/.bash_profile

In Terminal, type in which php again and look for the updated string. If everything was successful, It should output the new path to MAMP PHP install.

In case it doesn't output the correct path, try closing the terminal window (exit fully) and open again, it should apply the changes (Restart in short).




SOLUCION DE MI PROBLEMA
Yosemite comes with Apache 2.4 & PHP 5.5 preinstalled. You don't need MAMP, only MySQL or MariaDB.

Regardless, you can use PHP 5.5, PHP 5.4 or PHP 5.3 as needed. Try the following...

sudo mv /usr/local/bin/php /usr/local/bin/php55
sudo mv /usr/bin/php /usr/bin/php55
Install PHP 5.4

brew install php54 php54-mcrypt php54-mysql
Install PHP 5.3

brew unlink php54
brew install php53 php53-mcrypt php53-mysql
Switch to PHP 5.4

brew unlink php53
brew link php54
Switch to PHP 5.5

brew unlink php54
brew unlink php53
sudo ln -s /usr/local/bin/php55 /usr/local/bin/php
sudo ln -s /usr/bin/php55 /usr/bin/php
