(PHP) PHP Email Validator – Email MX DNS Record Check - mafhh14

Wed, 13 Mar 2013 19:07:33 GMT

Validating an email address is one of the hardest feats on the web. A valid email can be marketing gold, but an invalid email address is dead weight. Not only does it require a CPU-taxing PHP regular expression ("/^[A-z0-9\._-]+"."@" . "[A-z0-9][A-z0-9-]*". "(\.[A-z0-9_-]+)*"."\.([A-z]{2,6})$/"), the regular expression can be useless even after it's validated for format if the domain doesn't exist. A regular expression simply wont do -- we need to think more low-level. What does email at any domain require? A DNS MX record. Well, PHP provides a great solution to validate that there's a MX record for the provided email address' domain.

(Ruby) CPF and CNPJ validation classes using the Brazilian Government official algorithms - mabafu

Thu, 27 Oct 2011 03:06:50 GMT

#About# CPF and CNPJ are self-validated codes generated by Brazilian government. Being the CPF used to identify persons and CNJP to enterprises, organizations and so on. That said, I use to code the CPF/CNPJ algorithm when learning new programming languages. With Ruby, it got very clean and powerful because it's particular way to deal with "closures" (i.e. the ruby blocks, Procs and lambdas). To use Cpf or Cnpj classes, just instantite the respective classes passing the numbers to be validated. CPF has 11 digits and CNPJ has 14. In both cases the last two digits are calculated based on the previous ones. Module11 is the parent class of Cpf and Cnpj. You can use this class if you want to implement your own Module 11 validation algorithm. In this case, inherit from Module11 and initialize the new class with the proper parameters (i.e. input, formula, size, number_of_digits)

(Other) How to configure the output format of the W3 CSS Validator - noah

Wed, 16 Sep 2009 11:53:08 GMT

The W3 CSS validator is pretty simple to [install locally for use behind the firewall](http://www.emacswiki.org/emacs/FlymakeCSS). However, by default the validator spits out the whole CSS file after validation, which is inconvenient if your stylesheet is more than a few lines long. Unfortunately it's not so obvious how to configure the validator to give pretty-printed, human-readable output. In fact, all there is to it, is to choose a different output format from the several that are supported :) By default the validator .jar file gives you "text" output, which includes the stylesheet. To choose a different format, invoke the validator .jar file with an -output argument, like this: java -jar css-validator.jar -output local-file:foo.css where `` is any of xhtml, xml, text, soap12, json, ucn or gnu If you just want the errors as (html-escaped) plain text, but without the CSS included, use `gnu`
