Remove index and .php from URL

.htaccess

# This .htaccess will hide your index and .php in your URL, and serve the corresponding .php file
# Examples:
# /index.php -> / (index.php served if it is the DirectoryIndex)
# /abc.php -> /abc (abc.php served if abc does not exist)
# /path/to/app.php/path/info -> /path/to/app/path/info (/path/to/app.php served)
#
# Unsupported scenarios:
# file.php and file coexist (file.php can't be served)
# index.php not set as DirectoryIndex
# multiple index.* exist in a directory (don't know which to serve after it is rewritten out)
