So I did this:

alias php='/usr/bin/php'

Now php seems to work, but when I try doing "which php", it's outputting: -bash: which: command not found

alias is not the same thing as path. I'm guessing your path got screwed up somehow. Here is how you can fix it. Add these 2 lines to your ~/.bash_profile

export MAMP_PHP=/Applications/MAMP/bin/php/php5.5.10/bin
export PATH="$MAMP_PHP:$PATH"

assuming /Applications/MAMP/bin/php/php5.5.10/bin is the location of you MAMP php exit the terminal then open it again

Thank you! My php is working now! ^_^ <3

But I'm still having the mcrypt issue. :'(

/Applications/MAMP/htdocs/asl/laravel
Lindsays-MacBook-Pro-2:laravel TheFishbowl$ php artisan serve
Mcrypt PHP extension required.

2 things you can check

1. Do you have the correct php version when you type php -v you should see something like php5.5.10
2. Check if mcrypt is actually enabled by doing php -i | grep mcrypt you should see something like this mcrypt support => enabled

If it's not there go into /Applications/MAMP/bin/php/php5.5.10/conf/php.ini

and add

extension=mcrypt.so (search for all the other extensions being loaded)

restart mamp
