# Purpose: Use this script to standardize written code to be in compliance with Solis development standards and PHP 5 standards.
# What it does:
# - Converts function an variable names to lowercase (firs letter only)
# - Converts function call's first letter to lowercase (dynamic and static for MIOLO::)
# - Converts "var" instructions to public
# - Adds public on functions without visibility information
# - Converts file names: .inc -> .inc.php ; .class -> .class.php

# Convert function names to lowercase (firs letter)
echo -n "Converting function names... "
for i in $(find -name \*.php -exec grep "^ *\(public\|private\|\) *\(static\|\) function [A-Z][a-z]" {} -rl \;); do sed -i "s/function \([A-Z]\)\([a-z]\)/function \l\1\2/" $i; done
echo "done."

# Convert method invocations' first letter to lowercase (object)
