Today marks the launch of TwitterBash, a concept conceived and design by my good friend Judson Collier. [...] TwitterBash takes the concept of the long Internet-famous bash.org, which allows folks to post snippets and quote conversations from IRC, and applies it to Twitter. Just sign up for an account, then head to the submit page. Pop in the permalink for a tweet you want to quote and you're done.

The site runs on the PHP5 CodeIgniter framework allowing for fast and easy development. There's already a pretty good amount of content, so go over and check it out (and submit some of your own).

Escaping quotes or other meta characters in SQL can be painful unless you get lucky with your quoting style. [...] Even with PHP's "Heredoc" syntax something will need escaping, but with PHP 5.3's new "Nowdoc" syntax no escaping is needed.

The only difference between HEREDOC and NOWDOC is that the initial keyword (like the first END in this statement: <<<'END' text here END;) that can make worrying about complex quoting rules a thing of the past.

When someone uses htmlentities I've seen it time and time again that they expect that it filters variables from all XSS. This is wrong of course because the function requires a second parameter ENT_QUOTES which correctly replaces quote characters. Some developers aren't even aware that quotes can lead to XSS injection.

He reminds developers of the second parameter - the ENT_QUOTES parameter that correctly replaces quotes. Other people have mentions things in the comments as well like another optional parameter to force an encoding type and opinions about the function's use.

Ed Finkler agrees with me. Thanks Ed. :-) Listen to the podcast. It's a realistic assessment of the state of security in PHP.

He also includes a favorite quote from the podcast (as said by Ed):

If web developer doesn't understand common security issues they shouldn't be considered developers...[Web applications] essentially are dealing with data that someone is inputting there. As a developer of web applications, you are essentially stewards of that data.
