## Publications about PHP

To the best of our knowledge, the first article about PHP in a hard-copy magazine was published in the Czech mutation of Computerworld in the spring of 1998, and covered PHP 3.0. As with books, this was the first in a series of many articles published about PHP in various prominent magazines.

Articles about PHP appeared in Dr. Dobbs, Linux Enterprise, Linux Magazine and many more. Articles about migrating ASP-based applications to PHP under Windows even appear on Microsoft's very own MSDN!
