You probably need to fix it in the .bashrc file.

Do this:

Open the terminal and run this command:

nano ~/.bashrc 

Then add this line in the .bashrc file:

export PATH=$PATH:/usr/share/php/bin

Save and exit (ctrl + x)

I had the same issue after updating to Monterry. After some googling, I find out MacOS doesn't include PHP. You need Homebrew to install PHP again.

brew install php

https://daily-dev-tips.com/posts/installing-php-on-your-mac/

I have same problem and this is the solution that I use for this.

1. install Xcode using your terminal

    xcode-select --install
   

2. install homebrew using your terminal

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
   

   when it finish the process you need to add the homebrew in your path and for this put this code

    echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/**xxxxxxx**/.zprofile
    eval "$(/opt/homebrew/bin/brew shellenv)"
   

   xxxxxxx write your user name

   now you can check if homebrew is run correctly, use the next code.

    brew --version 
   

   you can see in the terminal the version that you have install in your pc

3. now is time for install php for this

    brew install php
   

   finally, you can try see the version of php installed

    php --version
   

When I update MacOS Monterey, PHP was remove. I found this article it useful and solve this problem for me. https://wpbeaches.com/updating-to-php-versions-7-4-and-8-on-macos-12-monterey

Add the PHP formulae

brew tap shivammathur/php

Choose the PHP version – this example uses 7.4

brew install shivammathur/php/php@7.4

Link the PHP Version

brew link --overwrite --force php@7.4

Restart the Terminal

php -v

Homebrew users:

This can happen simply because your php version is not linked.

Goto /usr/local/Cellar, list out the content and see what versions of php you have installed. You should see directories and symlinks as so:

lrwxr-xr-x    1 kazajhodo  admin      7 May 22  2019 php72 -> php@7.2
lrwxr-xr-x    1 kazajhodo  admin      7 Feb 26  2020 php73 -> php@7.3
lrwxr-xr-x    1 kazajhodo  admin      7 Jun 12  2020 php74 -> php@7.4
lrwxr-xr-x    1 kazajhodo  admin      7 Jan 22  2021 php80 -> php@8.0
lrwxr-xr-x    1 kazajhodo  admin      7 Jan  4 11:58 php81 -> php@8.1
drwxr-xr-x    3 kazajhodo  staff     96 Jan  4 11:34 php@7.2
drwxr-xr-x    3 kazajhodo  staff     96 Aug  8 19:32 php@7.3
drwxr-xr-x    4 kazajhodo  staff    128 Jan  4 11:55 php@7.4
lrwxr-xr-x    1 kazajhodo  admin     18 Jan 22  2021 php@8.0 -> /usr/local/bin/php
lrwxr-xr-x    1 kazajhodo  admin     18 Jan  4 11:58 php@8.1 -> /usr/local/bin/php

If the version you want is there, you can link it with brew link php@7.4.

Then your bash should have php defined.

Installing php again will also work, because it will add the symlink in the install process; but you only likely actually need the symlink.

If you want the latest PHP release in macOS Monterey then follow these steps:

1: brew tap shivammathur/php

2: brew install shivammathur/php/php@8.2

3: brew link --overwrite --force php@8.2

to check if its working, write this in the terminal: php -v

if you get something along the lines of PHP 8.2.0-dev (cli) then its working
