zsh: command not found: php. PHP is installed and working with MAMP-CodePudding

I am trying to use composer to install a google client library, but cannot install composer or use php on the command line.

I am using php 8.0.8 with MAMP and it is working fine, so I know it is installed. If I type php in the terminal, I receive the command not found message. Thinking it could be an environment variable, I have tried navigating to the php folder /Applications/MAMP/bin/php/php8.0.8/lib/php and tried the php command again, but still get the same error

I am using a Mac running Monterey

Change default Mac OS X PHP to MAMP's PHP Installation and Install Composer Package Management

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).

Install Composer Package Management

Now you can fire the command to install the composer globally (So you can access it from anywhere):

$ curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

You can verify your installation worked by typing the following command within the Terminal:

composer

It'll show you the current version and a list of commands you can use if the installation was successful.
