Sed parameter getting replaced with backslashes

I want to run search and replace and I am trying the following command:

sed -i "s/\$enviro ?=.*[^;]/ = 1;/g" constants.php

For some reason when I try and run this is turns into:

sed -i "s/\$enviro\ \?=.\*\[\^\;\]/\ =\ 1\;/g\" constants.php

This then gives errors:

sed: -e expression #1, char 28: unknown option to `s'

I simply want to run the regex \$enviro ?=.*[!;] and replace it with $enviro = 1;.

Input - a large config file, one of the lines being:

       $enviro = 0;

Output - still large config file:

$enviro = 1;

You can use this sed command:

sed -i.bak 's/\(\$enviro *=\).*/\1 1;/' constants.php
