Universal CTags version of Tim Pope's Effortless CTags for PHP

ctags.sh

#!/bin/sh
set -e
PATH="/usr/local/bin:$PATH"
dir="`git rev-parse --git-dir`"
trap 'rm -f "$dir/$$.tags"' EXIT
git ls-files | \
  ctags \
     --tag-relative=yes \
     -L - -f"$dir/$$.tags" \
     --languages=php,-javascript,sql
mv "$dir/$$.tags" "$dir/tags"

This is using universal ctags instead of exuberant ctags, since the old ctags' support for new PHP features is pretty much nil.

Also, this is for setting up a PHP project in the style of Tim Pope's Effortless Ctags article which has been a revelation for my vimming 😁
