The target platform is an important thing as Hazem mentioned.
From my professional experience if you were targeting the Java platform I would strongly recommend Eclipse over any other IDE.
It is rich in plugins and can integrate with many application servers, databases and version control systems.
It also includes many features which will make the developer very productive.
C and C++ on the other hand is very tough to say, because you have to also target an operating system.
I know that if you wish to create Linux apps targeting the KDE Desktop then the best IDE is KDevelop.
Though if you wish to do Kernel development then almost any IDE might be good...
a lot of people use tools like vi and emacs or any text editor with an integrated shell.

Eclipse for php NetBeans for java & javascript Visual Studio for .net (C# / VB) Dreamweaver for HTML & design

It depends on what's your target platform.
If you're a web designer just writing HTML/CSS/Javascript, if you are on a Mac, Coda is an excellent choice, on Windows you can use Sublime Text or Aptana Studio.
If you are a developer and writing for .Net, Visual Studio is your best friend.
For other platforms, Netbeans and Eclipse are decent choices.

I used to work on IDEs like Eclipse, NetBeans and Visual Studio, but there was always something missing with these softwares, untill I met PyChram when I was learning Python, then PhpStorm, finally I came to a conclusion that www.jetbrains.com has almost the perfect IDE for most of the popular programming languages and platforms.
I must say, they are really fascinating.

PhpStorm is really a good one for PHP.
Eclipse is good for Java.
and who can beat Visual Studio for .Net Platform :)

of course SUBLIME it is the best editor

but if you want one for java it will be NetBeans 

I highly recommend Visual Studio for .Net, web, and Cpp development.
You can even develop PHP applications with it using Phalanger (http://phalanger.com/).
I'm a .Net and web developer, and have tried Aptana and NetBeans mainly for JavaScript, and found out that Visual Studio is the best for the following reasons: - Powerful capabilities, nice UI, and in the same time, low memory and CPU footprint.
- Powerful designers for HTML and CSS.
- Powerful and lightweight editor for .Net languages and JavaScript, specially if combined with the JavaScript Parser (http://code.google.com/p/js-addin/) and Web Essentials (http://visualstudiogallery.msdn.microsoft.com/6ed4c78f-a23e-49ad-b5fd-369af0c2107f) extensions.
- You may use the Express editions and the Visual Studio Shell free of charge for developing commercial software.
- It keeps becoming better and better, and the 2012 version added many new capabilities and performance enhancements.

NetBeans for php , java , Html ,Html5 and cordova qt for C++ and visual studio for windows apps android studio for androidjust now i worked with you the right

depends if you are core coder, notepad++ should be fine, otherwise eclipse could be better free alternative, for paid users NetBeans is great.

for java you can use Eclipse for Ruby, PHP, Python you can use on of the JetBrains IDE's
