Regex to replace *_user_meta() API function calls with *_user_option() API function calls (to improve WordPress Network Compatability)

gistfile1.txt

# For get_user_meta: replace the function name, argument order & make sure no default value (3rd parameter) is passed to the get_user_option function

# FIND:
get_user_meta\(\s?(.*?),\s?([^,\)\s]*)\s?(,(.*?))?\)

# REPLACE:
get_user_option( $2, $1 )

# For update_user_meta: replace the function name & don't carry over the 4th $prev_value argument

# FIND:
update_user_meta\(\s?([^,\)\s]*?),\s?([^,\)\s]*),\s?([^,\)\s]*),?\s?([^\)]*?)?\)

# REPLACE:
update_user_option( $1, $2, $3 )

# Bonus
# Code output from the regex will have standards compliant whitespace, even if the offending function did not.
