phplint.sh

#!/bin/bash

# php linter of git tracked files
# passing --success argument will print no-error files in the list,
# otherwise, only files with parse errors will be displayed.

IFS=$'\n' #split filenames at newlines only

for file in `git ls-tree -r master --name-only`
do
    EXTENSION="${file##*.}"

    if [ "$EXTENSION" == "php" ] || [ "$EXTENSION" == "phtml" ]
    then
        RESULTS=`php -l $file`

        if [ "$RESULTS" == "No syntax errors detected in $file" ]
        then
            if [ -n "$1" ]
            then
                printf '\e[32m%s\e[0m\n' "${RESULTS}"
            fi
        else
            printf '\e[31m%s\e[0m\n' "${RESULTS}"
        fi
    fi
done
