# alias php to the latest PHP installed with MAMP
MAMP_PHP__LATEST=$(ls /Applications/MAMP/bin/php/ | sort -V | tail -1)
alias php="/Applications/MAMP/bin/php/${MAMP_PHP__LATEST}/bin/php -c \"/Library/Application Support/appsolute/MAMP PRO/conf/${MAMP_PHP__LATEST}.ini\""

# alias pear and pecl to the MAMP copies
alias pear="/Applications/MAMP/bin/php/${MAMP_PHP__LATEST}/bin/pear"
alias pecl="/Applications/MAMP/bin/php/${MAMP_PHP__LATEST}/bin/pecl"

# create aliases for every version of PHP installed with MAMP
# for every file in the MAMP php directory

	# if the item is a php version (not, say browscap.ini)
	if [[ "$phpv" == php* ]]; then
		# reformat e.g. php7.3.1 to php7_3_1
		php_v=$(echo "$phpv" | tr '.' '_')

		# for create an alias named like php7_3_1_mamp
