  • Purpose of PHP constructors

    - by Bharanikumar
    Hi, I am working with classes and object class structure, but not at a complex level – just classes and functions, then, in one place, instantiation. As to __construct and __destruct, please tell me very simply: what is the purpose of constructors and destructors? I know the school level theoretical explanation, but i am expecting something like in real world, as in which situations we have to use them. Provide also an example, please. Regards

  • How do i query to list out all commits by a user to a subversion repository?

    - by VDev
    The title pretty much sums up my question, I would like to find all commits I have ever done to the subversion repository. Not just commits in current snapshot. More importantly, I would like to organize the file lists by the SVN comment used while committing. Thank you Edit: I am thinking maybe a python or shell script that would parse the output of svn log | grep username to extract revisions and then pipes the output to svn log -r [revision numbers go here] Maybe some scripting gurus can help me out..

Is there a way I can use Joomla for that?

  • Java threads for the beginner

    - by Boba
    I've been trying to explain Java threading to a colleague who has never been exposed to multi-threaded applications, but apparently I'm not a very good teacher. Can anyone recommend a good online or offline resource that can explain threading in a simple, step-by-step manner? I know it's a complex topic, but surely there exists an article, book, or other explanation that can result in an "Aha! I get it, finally!" moment.

  • Simple pathfinding?

    - by pdx
    Does anyone know if there is a simple way to do pathfinding in PHP? I basically have a list of numbers (kinda like {origin:11485,outboundDirections:"11486,11487,11488"} and {origin:11487,outboundDirections:"11485,11676,94185"} and getting from 11485 to 94185 would result in 11485>11487>94185 with ways to "exixt", and I'm trying to figure out how to do this (it doesn't really have to be shortest path or anything AI-like, just a way to get from A to B) I have no idea where to start at all, unfortunately

  • why doesn't focus() work in the following line of jquery?

    - by jela
    The following code is intended to check if 4 numbers are entered in the blurred field. If not, the field value is deleted, and the field is focused. The deletion works fine, but the the call to focus() does not work. $('input.dateValue').live('blur',function(event){ if (!(/(\d){4}$/.test($(this).attr('value')))) $(this).attr('value','').focus(); }); Why does the call to focus() not focus the field?
