hi there. thanks for this great script. i used it thankfully the last years... but with the latest brew i experienced some troubles, so what i am thinking about is: with sierra and high sierra i do not use the built in apache anymore, as it is said here: https://getgrav.org/blog/macos-sierra-apache-multiple-php-versions

so i am using the brew httpd and brew does not want to start httpd with sudo or at least its not recommended.
so i modified the parts in this script here to stop and start apache with "brew services start httpd" and "brew services stop httpd"... in this script u are restarting it with sudo... when listing "brew services list", the httpd service is marked yellow...

didnt u experience some problems? wouldnt it be better to restart the brew apache with "brew services stop httpd" and "brew services start httpd"?

For macOS users this script might act a bit different.

The sed in macOS requires a suffix for the in-place option -i (see https://linux.die.net/man/1/sed).
It creates a file named httpd.conf-e because it uses the -e option as suffix argument.
Just change line 55 to:
sudo sed -i '' -e "/LoadModule php${majorOld}_module/s/^#*/#/" $apacheConf

Hint for macOS High Sierra users: If you run into /usr/local/sbin is not writeable errors, check that your /usr/local/sbin actually exists. If not, just creating it and chowning it to your user solves the problem.

    # Remove from PATH - ALL

    sed -i '' "/php@7.2/d" "$HOME/.zshrc"
    # Add new to PATH

Thank you for this script! Unfortunately it isn't changing the PATH for me, and so only Apache PHP is changed and not CLI PHP. I use zsh and Homebrew PHP. Based on the comments above this is supposed to work, but for me it just doesn't.

I came up with this Bash function to call instead of sphp. It calls sphp and then finds the PATH within .zshrc and replaces it:

function switch_php() {
	CURR_PHP_VERSION=$(php -v | tail -r | tail -n 1 | cut -d " " -f 2 | cut -c 1-3)
	NEW_PHP_VERSION=$1

	if [ "$CURR_PHP_VERSION" = "$NEW_PHP_VERSION" ]; 
	then
		echo "Already on $NEW_PHP_VERSION ya idiot."
	else
		echo "Switching from $CURR_PHP_VERSION to $NEW_PHP_VERSION."

		sphp $NEW_PHP_VERSION

		sed -i '' "s/php@$CURR_PHP_VERSION/php@$NEW_PHP_VERSION/g" "$HOME/.zshrc"
		
		source ~/.zshrc

		echo "New CLI PHP:"
		php -v

	fi
}

Call it like so: switch_php 7.2.
