if $HAS_PHP_CS_FIXER; then
    git status --porcelain | grep -e '^[AM]\(.*\).php$' | cut -c 3- | while read line; do
        $PHP_CS_FIXER fix --config-file=$ROOT/.php_cs --verbose "$line";
        git add "$line";
    done
else
    echo ""

    echo ""
    echo "  composer require --dev fabpot/php-cs-fixer:dev-master"
    echo ""

echo "php-cs-fixer pre commit hook finish"

Grep pattern is missing heading whitespace:

# instead of 
grep -e '^[AM]\(.*\).php$'

# do
grep -e '^\s*[AM]\(.*\).php$'

Actually, ls-files does a better job:

git ls-files -m | grep -e '.php$' | xargs vendor/bin/php-cs-fixer fix

use lint staged is also a nice solution https://sebastiandedeyne.com/running-php-cs-fixer-on-every-commit-with-husky-and-lint-staged/
