It is worth adding that you will need to escape a different set of characters on ruby than in php. For instance the curly braces ‘{’, ‘}’, and ‘#’ need to be escaped in ruby because they have special meaning in strings.

We can achieve preg_replace_callback functionality in ruby this way
def my_test_method(matches)
return “_pk”
end
my_string = ‘joe@example@example.com; walter@example.org‘
str = my_string.gsub(/@([a-z0-9-]+)/){ |match| my_test_method(match) }
puts str

Thanks for nice article. Its really very helpful to me.

You said “by enclosing the pattern in backslashes”, but I think you meant the forward slash in this case?
