I don't get you, this plugin can give a tip when create PHP scripts?
or dreamweaver can preview php files?
there are a lot of software specialize for PHP... dreamweaver has no built in tool for php code...
So let me get you right there.
You want the read ahead function of Dreamweaver right? You type in the the bracket and it lists all of what you can do. i am with you so far.
But you want it to be able to do the same for PHP code?
Am I getting what you are trying to say?
When you type php code, it will show you with a code completion feature what variables you can insert and what the function is. I believe no IDE makes a programmer or scripter so lazy as to not even need to type in your code, not even VisualBASIC. The feature you speak of is a feature only web designers and writers have the ability to use or care to use. Programmers and scripters don't find it as useful - some even dispise it. One reason why IDEs don't have code completion for scripting and programming languages is just so the programmer knows what he is doing at all times and nothing that he doesn't want will be added.
