Update PHP to 7.4 macOS Catalina with brew - php

Question

I try to update my PHP version to 7.4 on macOS Catalina with brew.
I did brew install php#7.4
If I check my version php -v, I still see the old version PHP 7.3.11?
What do I have to do?
Update:
After brew doctor I get:
Warning: Homebrew's sbin was not found in your PATH but you have
installed formulae that put executables in /usr/local/sbin. Consider
setting the PATH for example like so: echo 'export
PATH="/usr/local/sbin:$PATH"' >> ~/.profile

Answer 1

You can find my similar answer for php#7.2.
brew install php#7.4
brew link --force --overwrite php#7.4
brew services start php#7.4
export PATH="/usr/local/opt/php#7.4/bin:$PATH"
export PATH="/usr/local/opt/php#7.4/sbin:$PATH"

Answer 2

try:
brew update
brew upgrade php
php -v
brew services start php
or
brew services restart php
if you use apache server:
sudo apachectl restart
if you use ngnix
sudo nginx -s reload
Edit:
brew unlink php#7.3
brew link php#7.4

Answer 3

If anyone want to downgrade php from latest 8.1.2 to 7.4 on systems demand, try the below commands with homebrew:
Installing PHP 7.4 :
brew install php#7.4
brew services restart php
brew unlink php#8.1
brew link php#7.4
echo 'export PATH="/usr/local/opt/php#7.4/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/php#7.4/sbin:$PATH"' >> ~/.zshrc
Or
export PATH="/usr/local/opt/php#7.4/bin:$PATH"
export PATH="/usr/local/opt/php#7.4/sbin:$PATH"

Using terminal of MacOS. Don't use terminal in vscode.

Answer 5

I recently faced this issue, all the suggestion here didn't work until I ran:
xcode-select --install
Then ran the command I was trying before and the error stopped, for my case it was php
dyld: Library not loaded: /usr/local/opt/openldap/lib/libldap-2.4.2.dylib
Referenced from: /usr/local/opt/php#7.4/bin/php
Reason: image not found
zsh: abort php -v

Answer 6

I move to directory by: cd /usr/local
Find the file location by: find /usr/local/ -name libphp7.so. (Then get the file location at: /usr/local//Cellar/php#7.4/7.4.23/lib/httpd/modules/libphp7.so. I copy this.)
I open the file by: sudo vim /etc/apache2/httpd.conf
Look for the line by: /libphp7.so
Uncomment the line and update the line by: LoadModule php7_module /usr/local//Cellar/php#7.4/7.4.23/lib/httpd/modules/libphp7.so
Restart apache by: sudo apachectl restart
