running command in bash script producing error

Question

problem

Im trying to write a bash script that wraps phpbrew switch so that I can switch the apache module at the same time. Everything is working, except that I can't get the phpbrew switch php-7.0.01 to run properly.

code ($version being fed by input)

if [ -v version ]; then
        phpbrew switch php-$version
fi

error

Invalid argument php-7.0.1

running phpbrew switch php-7.0.1 executes with no errors.

Is there something odd going on with phpbrew? or am I trying to do something silly in bash?

full script

#!/bin/bash
# wraps phpbrew switch to enable apache switching

module_path=/usr/lib/apache2/modules
if [ $1 ]; then
        echo "switching php to version ${1}..."
        if [ $1 = "5.6.4" ]; then
                set=5
                version=5.6.4
                so_path=libphp5.6.4.so
        fi
        if [ $1 = "5.6.15" ]; then
                set=5
                version=5.6.15
                so_path=libphp5.6.15.so
        fi
        if [ $1 = "7.1" ]; then
                set=7
                version=7.0.1
                so_path=libphp7.1.0-dev.so
        fi
fi
echo "version selected = ${version}"

if [ -v version ]; then
        phpbrew switch php-$version

        echo "" > /etc/apache2/mods-available/php7.load
        echo "" > /etc/apache2/mods-available/php5.load
        echo "LoadModule php${set}_module $module_path/${so_path}" > /etc/apache2/mods-available/php${set}.load
        service apache2 restart
else
        echo "no version set"
fi

entry into terminal

./switchphp.sh 7.1

full output

ok, so managed to get an answer on github

all I needed to do was put

source $HOME/.phpbrew/bashrc
phpbrew switch php-${version}

before the command call in the bash file. Clearly wasnt pulling the bashrc from my home dir while in the script.
