Mr_J Posted December 10, 2008 Share Posted December 10, 2008 Hi all, Since I started programing in php, I found it very difficult to figure out WHY and WHEN and WHERE to use whatever I need to do. I managed to help someone recently. In the php section of the page, I did the following: Validate($username,&$password,&$retro,&$acc); //Describes what we are going to validate if ($retro == '3'): //1st retro=the error when the username is invalid more php... $mysql = mysql_connect('xxx.your-server.de', 'usrname','pw') or die("Could not connect : " . mysql_error()); //connect to server or error occured mysql_select_db("the_database") or die("Could not select database"); //select the database where usrs are stored Just in short, I added a lot of comments to explain exactly what I do and why I do it. I`m sure this is going to help him not only to understand but learn faster. I know there is no quick way about learning but like supposed most of us, Everything I know about programming I had to teach myself. I only finished school with no other qualifications or after school studies. Lets make the world a better place as HELL can`t be this bad Just a thought...

Mchl Posted December 10, 2008 Share Posted December 10, 2008 While commenting the code is indeed important, commenting every line of code, virtually translating programming language into human language, is not necessarily the best approach.

grandman Posted December 10, 2008 Share Posted December 10, 2008 While commenting the code is indeed important, commenting every line of code, virtually translating programming language into human language, is not necessarily the best approach. I can't disagree more, I wish when I first started to learn php, and asked for help on a forum someone had answered that way. It would have helped me tremendously. Even though I'm still learning, I use books, and code downloaded (which I dissect). Every forum seems to answer a question with a question, why can't we just tell someone (at least the general direction) of finding the answer.

GingerRobot Posted December 10, 2008 Share Posted December 10, 2008 Comments really depend on your purpose. Sure, if you're writing a piece of code to explain something to someone, then it does usually help to add in plenty of comments - mainly because you've no idea of their level of expertise and general code reading ability; what may seem obvious to you could be very ambiguous to them. However, i would never write code like that as general practice. Comments should generally be used to explain the purpose of an entire program/file/class/function or to explain and oddities/ambiguities in your code. For the most part, people can understand what your code is doing from reading it; there's no need to explain every line.

keiran420 Posted December 10, 2008 Share Posted December 10, 2008 INDENTATION INDENTATION INDENTATION It makes code readable, and it makes it easy to see what gets executed when what happenes.../ As for comments, depends who is gonna read your code, comment what needs to be commented explained...

Mr_J Posted December 10, 2008 Author Share Posted December 10, 2008 I agree to all of you. My point I`m trying to make is that I found it difficult learning to program just because someone told me what to code. It worked but I had no clue why or what is going to happen. Like I have mentioned, I have no qualifications and all of my knowledge came from self-propelled studies and of course the internet and forums. Thanks for the patrisipation Jaco PS. I launched my 8th website this year and only started coding about 6months ago Thanks for all you guys, you indeed are contributing to "MAKE THE WORLD A BETTER PLACE" Peace Link to comment https://forums.phpfreaks.com/topic/136326-how-about-this-to-help-everyone/#findComment-711348 Share on other sites More sharing options...
