How can I permanently add Homebrew to my PATH?

Create/open the ~/.zshrc file and add this line to it: export PATH=$PATH:/opt/homebrew/bin

Installing homebrew and getting the PATH correct (permanently)

Can you type this on the terminal?

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

The re-installation should fix the PATH.

which brew
/usr/local/bin/brew

Cannot update PATH to accommodate Homebrew commands

By running /opt/homebrew/bin/brew doctor as noted in the warning as opposed to brew doctor I was given the correct notation for updating my .zshrc file export PATH="/opt/homebrew/bin:$PATH as opposed to export PATH=/usr/local/bin:$PATH as indicated in several answers to similar questions. After running source ~/.zshrc and brew doctor the system confirmed the path had been updated properly.

Changing the Homebrew Apache PATH variable

I found the answer here.

To change Apache environment variables when Apache was installed with Homebrew, edit the homebrew.mxcl.httpd24.plist file located in /usr/local/Cellar/httpd24/your version of Apache/.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"     "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>homebrew.mxcl.httpd24</string>
  <!-- add this -->
  <key>EnvironmentVariables</key>
  <dict>
   <key>PATH</key>
   <string>/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin</string>
  </dict>
  <!-- end add -->
  <key>ProgramArguments</key>
  <array>
    <string>/usr/local/opt/httpd24/bin/httpd</string>
    <string>-D</string>
    <string>FOREGROUND</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>

Then restart Apache.

Getting a warning when installing homebrew on MacOS Big Sur (M1 chip)

I had the same issue today, on Mac OS Big Sur (with M1 chip).
The problem is indicated in the warning : Warning: /opt/homebrew/bin is not in your PATH. It seems that it is the directory where the binaries of hombrew are put.
To resolve, you can do :

1. Edit your ~/.zshrc or ~/.bashrc with at the end of file:

export PATH=/opt/homebrew/bin:$PATH

After this, tap source ~/.zshrc in your terminal or restart it.

For more infos about the current status of Homebrew on Mac with a M1 chip :
Apple Silicon support in Homebrew

Edit :
As mentioned by @kangkyu in this comment, Homebrew is changing to version 3.0.0 which supports officially Apple Silicon. If you have a prior version just brew update.
