Simple if statement in bash doesn't work 2

Question

I have this code in bash

#!/bin/bash       
echo "php version"
read NAME
if ["$NAME" = "5.6"] 
then
    sudo a2dismod php7.1
    sudo a2enmod php5.6
    sudo service apache2 restart
    sudo update-alternatives --set php /usr/bin/php5.6
else
    sudo a2dismod php5.6
    sudo a2enmod php7.1
    sudo service apache2 restart
    sudo update-alternatives --set php /usr/bin/php7.1
fi

But problem is that if don`t work as I expect, because when I run

./enphp.sh

I got this error:

/home/irebega/bash/enphp.sh: line 4: [5.6: command not found
