The latest macOS versions of Big Sur and Catalina currently ship with PHP 7.3 and have a deprecation notice that they intend to drop support for PHP altogether in a future upgrade.
You can see this by running a
<? phpinfo(); ?> function in a webhosted file or running
php -v on the command line.
admin@192-168-1-105 Documents % php -v WARNING: PHP is not recommended PHP is included in macOS for compatibility with legacy software. Future versions of macOS will not include PHP. PHP 7.3.24-(to be removed in future macOS) (cli) (built: Dec 21 2020 21:33:25) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.24, Copyright (c) 1998-2018 Zend Technologies
So moving forward the best solution is to use Homebrew to install and then choose whichever version of PHP you want including 7.4 and version 8.
So once you have Homebrew installed on your macOS a particular PHP Homebrew formulae will need to be added from this maintainer, what is great about this, is all PHP versions are available whereas only some versions are available on the default Homebrew formulas.
After Homebrew install, follow the below:
Add the PHP formulae
brew tap shivammathur/php
Choose the PHP version – example uses 7.4
brew install email@example.com
Other options are
- firstname.lastname@example.org or known as just php
Link the PHP Version
brew link --overwrite --force email@example.com
Change your version to match
Restart the Terminal
You should now see the new version, to change to another version just repeat the process from the
brew install... then unlink and link in the new PHP version by issuing a command like below but with your correct version:
brew unlink php && brew link --overwrite --force firstname.lastname@example.org
Using new PHP in macOS Shipped Apache
If you are using macOS in built shipped Apache, you can use the new PHP version by editing the Apache file:
sudo nano /etc/apache2/httpd.conf
Find the PHP module and comment it out and add in the new PHP version path:
#LoadModule php7_module libexec/apache2/libphp7.so LoadModule php7_module /email@example.com/lib/httpd/modules/libphp7.so
sudo apachectl restart
Now the new PHP version will be used.
You could download all the versions and just uncomment the one you want if you intend to swap around:
#LoadModule php5_module /firstname.lastname@example.org/lib/httpd/modules/libphp5.so #LoadModule php7_module /email@example.com/lib/httpd/modules/libphp7.so #LoadModule php7_module /firstname.lastname@example.org/lib/httpd/modules/libphp7.so #LoadModule php7_module /email@example.com/lib/httpd/modules/libphp7.so #LoadModule php7_module /firstname.lastname@example.org/lib/httpd/modules/libphp7.so LoadModule php7_module /email@example.com/lib/httpd/modules/libphp7.so #LoadModule php_module /firstname.lastname@example.org/lib/httpd/modules/libphp.so #LoadModule php_module /email@example.com/lib/httpd/modules/libphp.so
PHP 8 and macOS Apache
One extra step is needed for PHP 8 and macOS bundled Apache:
sudo nano /etc/apache2/httpd.conf
Add the new PHP 8 and comment out the old one.
LoadModule php_module /firstname.lastname@example.org/lib/httpd/modules/libphp.so
Go to the end of the file and add:
<FilesMatch .php$> SetHandler application/x-httpd-php </FilesMatch>
Removing Older Homebrew PHP version (optional)
If you have the older PHP formulas from an older Homebrew installation, you may wish to remove these:
rm -rf $(brew --cellar)/php
Remove old PHP Launch Agents and daemons, if present:
rm -f ~/Library/LaunchAgents/homebrew.mxcl.php* rm -f /Library/LaunchAgents/homebrew.mxcl.php* rm -f /Library/LaunchDaemons/homebrew.mxcl.php*
Remove the deprecated
homebrew/php tap, if present:
brew untap homebrew/php
Run brew cleanup:
