HTTP Authentication on PHP as CGI (like Dreamhost)

Using PHP's HTTP Authentication is a simple way to protect scripts behind a login/password prompt. There's one little problem: it's supposed to work only on PHP as an Apache module, not the CGI version. It took me a while, hair pulling and some googling to get a basic HTTP Auth system working on Dreamhost's PHP as CGI so for my…

The thing is: when you submit a form with empty fields, empty values are POSTed, except for checkboxes and radio buttons which are not posted at all, just as if they were no such field in the form.

Javascript basename() and dirname()

For my next stuff I needed the Javascript equivalents of PHP functions basename() and dirname(). Nothing genius: < View plain text > javascript function basename(path) { return path.replace(/\\/g,'/').replace( /.*\//, " ); } function dirname(path) { return path.replace(/\\/g,'/').replace(/\/[^\/]*$/, ");; } It obviously supports paths like /home/ozh/stuff.php, http://site.com/file.ext or double backslashed Win32 paths such as C:\\dir\\document.txt.
