In PHP Cookbook, the only use of ereg I found was in the section where the books was explaining how to convert from ereg to preg_match. Or an occasional mention that said you could do it with ereg but preg_match was better. But, I might have missed something. Practical Web 2.0 Applications with PHP, published in 2008, uses PCRE functions. Wicked Cool PHP, published in 2008, uses the PCRE functions. The book PHP & MySQL Web Development For Dummies, published in 2008, uses only PCRE funcitons. Doesn't even mention ereg. PHP & MySQL for Dummies sells pretty well. Its fourth edition will be released next month. It uses only PCRE, does not mention ereg. So, it appears that around 2007 most authors recognized that they needed to begin moving readers to the PCRE functions.
