Global Find and Replace in Dreamweaver Web Development

There are quite a number of web developers who experienced the previous techniques in performing global find and replace. They had to go into the web server and run scripts like sed and awk on their files. But methods like these can be quite complex especially when the regex is badly formed. Now, those days are over, thanks to the continuous evolving of technology. If you want to perform global find and replace on your website, there are web editors that will help you deal with this task. You can easily carry this one out and you will agree that this is pretty convenient. If you are not using global find and replace software, you ought to try one now.

Let us say that you would like to perform a global search and replace using Adobe Dreamweaver. This is actually one of the easiest methods that you can use. Whether you will be working on a current file or any other files that you have on your website, Dreamweaver will be able to assist you. After you have performed a global find and replace string or file using the software, you will make it to a point to use it anytime you can.

So the first step is to search in a certain file. To do this, open the file that you will use in Dreamweaver. Now, select the option that says “Find and Replace.” This can be found in the Edit menu or you can simply access this using the shortcut Ctrl+F or Cmd+F. Now, enter the words that you want to find in the search box and in the replace box, type the words that you want to replace the word in the first box. Ensure that you have selected “Current Document” before you proceed. Now, click on the Replace button. You can keep on clicking the button until you have replaced all the strings or files that you want to modify.

Now, if you want to perform a global find and replace task on an entire website, open Dreamweaver and select the predefined site. Highlight the files that you see in the folder list that you want to search through. Once again, click on the Edit menu and then “Find and Replace” or you can use the shortcut keys that have been mentioned earlier. Now, type the words that you want to find and replace in the appropriate boxes. Make certain that you have selected the option “Selected Files in Site” so that you can search the files in your website. Otherwise, select “Open Documents” in order to only search within the files that you have opened for editing. Another option is to select “Entire Current Local Site” to search all the pages in that website. Now, you can click on “Replace All.”

Just click on “Yes” when Dreamweaver alerts you that you will not be able to undo the changes that you have made. The results for the search will be displayed just below the window of the site in the Search pane.

PHP As The Best Web Development Language

Developers can choose from many scripting languages while developing web applications. Some of the programming languages that developers use commonly are CGI, Perl, ASP and PHP. However, PHP has certain benefits due to which it has become the most popular web development language. IT companies ranging from small to big are using PHP for creating different types of web applications. One can realize the efficiency of the language from the fact that huge applications like Facebook use PHP. Web developers having knowledge and experience in PHP are in high demand in the present times.

Developers are choosing PHP over the other languages due to the following reasons.

Easy to Learn and Simple

The language is easier to grasp than many other programming languages. This is because the language has similarity with languages like Java and C. Even if you know only HTML, learning PHP would be quite easy for you. The language is ideal for beginners since it is easy to understand and clear.

Freedom

PHP offers a higher level of freedom as compared to languages like ASP. NET. The language is an open source. You can use any text editor to write the code. Some of the common text editors which you can use are Notepad, Bluefish, Emacs. On the other hand, while using ASP. NET, you can only use Microsoft Visual Studio for creating the code. PHP is also not OS specific. PHP runs well on operating systems like UNIX, Windows and Linux.

Automatic Refreshment

The language creates dynamic websites that refresh automatically. If you use PHP for developing a website, you do not need to make any changes manually for refreshing it.

Integration:

The language has created more than 30% of the applications present in the World Wide Web. The language integrates with various systems like Pusher. Almost every industry is using the language including large corporations, government, hospitals and banks.

Frameworks

You can find a large number of PHP frameworks. These frameworks help you to carry out a variety of tasks using PHP. You can do tasks like code reuse, session management and finding database libraries easily using PHP frameworks. A popular PHP framework is Slim.

Support

You can find support and documentation for PHP quite easily. The support coming with the language is completely free. You can find many blogs and forums online to help you if you face any coding problem. You can also find support through social media. Among all scripting languages, the user base of PHP is largest. This is one of the reasons behind such a huge support community of the language.

Easy to Solve Problems

Web developers face programming problems very often. In case of PHP, you can easily find the issues and fix them. In case of other languages, you cannot fix problems that easily.

Object Oriented

The language is capable of calling Windows and Java COM objects. You can also create custom classes. Other classes can borrow from custom classes. This increases the efficiency of the language.

These are the major advantages of PHP over other scripting languages. Besides, the language is an open source and free. Applications developed using PHP are very fast and have a high level of security. All these factors have made the language highly popular in the word of web development.

Semantic Web Development

Introduction

Semantic Web Development and dealing with complexity is a tricky issue. Representing information is a problem where complexity can preclude any single approach. In order to find our way around large quantities of information it needs to be structured. But the information already exists and is still being created, so this makes it a moving target.

I’m sure such matters will be covered at the www2006 conference at Edinburgh .

The structuring of ontologies from the top down can be useful, but can only be achieved where the ontology developers have some control over the information. Much of web development and other creation of information is bottom up, in that there is no controlling authority. This is good for inclusiveness and speed of development, and something that encourages community, and encourages individuals to create their own content, which is a good thing. In his interview with the British Computer Society Tim Berners-Lee http://dig.csail.mit.edu/breadcrumbs/blog/4 answers a question on ontologies. He talks of a top level ontology that can be created to hold certain terms and the need to find out who is using these terms, so that other web pages and databases can be categorised. This would be achieved using URIs (Universal Resource Identifier) and RDF (Resource Description Framework). In answer to what Tim Berners-Lee hopes to achieve, he talks of this bottom up development that is going on, using blogs, and wikis etc and a possible approach of ‘web science’ – ‘the science and engineering of web based things that have a bottom up Web-like structure’.

I think this approach is highly relevant to my PhD research on user-driven programming, with University of the West of England (UWE – Bristol). Not everyone has the time to learn programming especially if their main expertise is elsewhere. They then have to ask others to do the development for them and this leads to delays and mis-understandings. The approach advocated here could enable visual creation of software by members of a community. Members of this community would not need advanced programming skills if other members with more advanced development skills could create a suitable interface for the creation of software. This could be achieved in a similar way to that used in visual web page creation tools, or word processor and spreadsheet software. Also the members who do possess advanced skills could provide ways of sorting, searching and navigating the programs created using the visual development tools. Members could work with either or both groups, according to their skills and interests.

A good first step would be to link communities and sites that have a mix of those with advanced software skills who want to encourage and enable others to learn to program, and of new starters who want to learn. This could involve those who are willing to try out new techniques to make it easier for new starters to train learn and gain experience.
