Today I needed to implement an unobstrusive replacement for native alert and confirm functions for a client’s project. I searched a lot of libs and solutions but none of them worked as I wanted.

There are many ways to manage big XML files in php. When I say large, is really large, 10, 20, 30 mebabytes. If we were open a file like this on a common server, we certainly will have a time-out error. This is because we usually use SimpleXML functions. This extensions is, in fact, a “Tree-based parser”, just like “DOM Parser”. They work great in small-medium XML files (~1MB). They put the whole content on memory, and then, parse it. But when we face a big content, the only option is the “Stream-based parsers”. These are more efficiently and faster, because it read the file on demand, and don`t crush your server`s memory.

Esta extensão tem um “Tree-based parser”, assim como o “DOM [...]

Well, there’s a few tutorials around, including the official CI wiki suggesting a more friendly pagination implementation, with page numbers on the link, because the actual CI pagination works with the offset from the database. The code I use today is from the official wiki, but the search [...]

Depois de longa pausa, cá estou. Bom, existem alguns tutoriais e artigos por aí, inclusive no wiki do CodeIgniter explicando como usar uma paginação mais coerente. Digo isso pois a paginação atual do CI trabalha com o offset do SQL, e não com o número da página em si. O código que uso hoje foi [...]
