Difference between PHP/.net/DHTML/Java

can you please tell me what is the area where these three languages have edge over each other ...

Actually i have a great interest in web development and till now i know html only...
i am not able to figur out which language i should opt for my summer training

please tell me which is the best technology in the market at this time or in near future.. where these technologies are important...

i m a second year engineering student.. what should i do

you tell me your view about any web development language you know

can you tell me for which type of sites are these technologies mainly/preferably used(include examples if you can)?

Help me guys i m in a great dilema... Please clear my doubts..

it would be really grateful..

Very well written, Slashfear 😀.

@ Sarvesh: Allow me to add to Slashfear's response.

To begin with, let's try to have the concept of web development clear. I'm guessing you want to be developing websites and creating web apps (web - applications).

Web development involves number of programming/scripting languages. The most popular is PHP along with mySQL (database) and often used in combination with HTML, JavaScript and CSS.

In order to begin your career in web development, HTML & CSS should be your starting point. It should not take you more than a week of dedicated efforts to gain fair control over HTML & CSS.

Next you should start with PHP & MySQL. If you like CE, I'll be happy to tell you that CE runs on PHP & mySQL. 😀

But todays world demands one more language: JavaScript that lets you add all the buzz to your webpages. The world is already stepping ahead with a new (not very new anymore) technology called AJAX.

I recommend that you spend 2-3 days learning about all the things I mentioned in this post to get a clear idea of what does what.

I'd also suggest that you take a look at Ruby Programming Language that's gaining popularity for rapid web app development?

Thanks Big K !!!! Its really a pleasure being in this place 😁

Sorry for late reply! actually had my exams these days in between!

Thanks a lot Slashfear and BigK

Your advice has certainly widened my horizon and i am now feeling a lot more clear about the direction in which i have to proceed..

Thanks again

plz tell me how to creat websiet in use dhtml\.net\java

saurabh dixiy

plz tell me how to creat websiet in use dhtml\.net\java

The first step would be to become familiar with these tools [viz. DHTML/.Net/Java]

@slashfear,@BigK: Do you think that i can gain grip over php/flash/html/css/.net/mysql through the online material available.

do you think it has sufficient to explain properly and cover advanced features as well?

Dont mind but i am asking this because i have summer training in my college so i was wondering should i shell out 5000 ruppees to learn php or .net or rather arrange a training certificate from somewhere and learn these languages through the online material available.

this dilema is because i am worried that if i not join training i will not be losing anything na? and studying staying at home will be right and cover whole sphere of things regarding these technologies that would have been told or taught in the paid training.

and last but not least i have the support and guidance and help regarding anything from the wonderful CRAZY ENGINEERS to help sail me thirough the troubled waters and make my journey of learning new things more and more creative.

@BigK: You laid emphasis on HTML and CSS as my starting point.

Can you please tell me how much i need to know in HTML as i am somewhat familiar in html(tags, syntax, backgrong, inserting images and sound, tables,formatting images and text).
How do you rate this much on a scale of 10 so that i can know how much i need to know more about?(i know it is very less but still)

Also please tell me the things i should know in HTML.
and if possible please tell some points about css as well as in things i must cover.

First of all, strict NO to the following -

rather arrange a training certificate from somewhere

That's not what CEan will ever do.

Q1. do you think it has sufficient to explain properly and cover advanced features as well?

Answer: Internet has got much more information about the basics & the advanced concepts/features about HTML that you'd ever imagine. HTML ain't a rocket science; don't worry.

Q2: Do you think that i can gain grip over php/flash/html/css/.net/mysql through the online material available.

Answer: One by one, my friend. First spend some time reading about these languages/tools on the Internet and select the ones that appeal you more than others. A typical web developer will have command over HTML, CSS, PHP, JavaScript & MySQL. Flash may take a back seat; but that's my personal opinion.

Q3: Can you please tell me how much i need to know in HTML as i am somewhat familiar in html(tags, syntax, backgrong, inserting images and sound, tables,formatting images and text).

Answer: Depends entirely upon what you want to do. HTML produces plain images. You need a scripting language to add pizzaz to your web pages. HTML is not a big deal as I said. Let's say, if you develop interest in HTML, one week dedicated study [4-6 hours daily] would make you familiar with HTML. Of course you will learn a LOT with experience. There are no short-cuts.

It's impossible to point out how much you need to know about HTML. I'd say, instead of sitting on the pool-side and wondering whether the water is hot or cold; just jump in. You'll love what you'll discover. Find a nice tutorial site on the web to tell you about HTML and start building some nice web pages right away.

The same story goes with CSS. The modern CSS techniques have taken the web development to newer levels. Start with HTML and you'll have a detailed understanding of the point I'm trying to make here.

thanks BigK i have completely understood what do yuo want to say..
and dont misunderstand me in my saying that i would arrange a training certificate from anywhere..
i was just trying to ask that i will have to shell out 5000/- for thing that i can learn though internet free of cost.. php/.net/ shell scripting are the only options available and since a training certificate is necessary to show in college due to college curriculum..

so do you still think i was doing wrong?

well my college has said that i can pay for one of the three training LAMP/.net/shell scripting my teacher has said that i can attend the theory class(not practical class) of any one other training also so what would you suggest?

what should be priorities?

This is the course for lamp they are offering Please have a look:

Training Schedule: 4 Hrs. Daily, 5 Days/Week

do you think this is fine for six (or 8 )weeks of traning I think it is too much for that? am i right (ie are they befooling us) or they can really cover that..

is any important thing missing from this..
is thre anything unnecessary thing put up in this course for showing us that they are going to covr a whole lot things?

Hi Sarvash,

Sorry for late reply i was busy with work, Alright let me tell my point of view,

What Big_k said is right, you can learn basics as well as advanced concepts through internet buddy (remember only your mom and dad could not be found in internet!!😉 other than that you can find everything in internet 😁)

my opinion would be dont waste your time in going to some course and spend money. Instead keep these syllabus as your guideline (That's the smarter way to do 😀) and you can learn online and if you want any help, we are here to help you out!!

and trust me dude when you learn course from outside its going to be of no use in practical software industry. so try to learn yourself and figure out, explore new things then only you have a practical exposure and master yourself as well as you will be confident that you know that language!!!



- Arvind (slashfear)

for web development understand client server architecture and some basics about how they work.. because web application works differently then desktop application

if u know c then PHP is easy for u as a beginner use Dreamweaver as a text editor its batter then other editors

always use MySql as a database with PHP application as its free and light weight

also study about flash to make ur web more attractive

study CSS and how to use it

after all that use PHP smarty templates to design your web it and separate ur presentation logic from business logic

if u want more help about PHP and MySql mail me at <removed>

thanks slashfear for th reply and support

thanks to jignesh too
