All You Need To Know About Php Application Development

PHP was developed originally for fabricating dynamic Web pages

. It is a server side script language that is deduced by a server consisting of a PHP processor. When it comes to PHP Application Development, it is important to write proper codes for solutions rather than opting for easy codes that usually turn out to be poorly written. Working on proper fundamentals is the real key for good development.

Structure of Directory

It is vital to establish a well - organized system for the project files being prepared. It is also advisable to name the directories appropriately relevant to the application and location. For example, files that a user would normally access the Web browser directly could be named "public_html" directory. Every name of every directory must be meaningful and understandable.

The files that are not accessed through the public Web directory would be present in the centralized location. These would be accessed by scripts. There are some security related facts that need to be considered while working on this stage. The considerations comprise the prevention of directory listings, password protection of areas that need to be logged in through .hta and blocking hotlinks.

Conventions of File naming

After the directory structure stage has been developed, the next step is to work on the file name conventions. In order to keep track of the functions of the files, it is necessary to name the files appropriately according to the functions that they perform. The most common ways of naming the files are by using either word separation or camel caps.

For example, word separation would have the name as 'new_employee_detail.php' and with camel caps it would be written as 'newEmployeeDetail.php'. Using camel caps is the convention preferred by application developers in most cases.

Coding

It is very important to place the logical part of the application, which is the code, in the same order of convention as the physical part. The various aspects such as functions, variables, classes and constants must be evidently and clearly formatted.

While reading the code, the developer or anyone else must be able to understand what the code is written to perform without having to read the function definition. Such a code would be deemed to be well written.

The following provide the basic rules for coding conventions.

* Appropriate names must be given to variables, functions, class variables and class methods, by using camel caps convention.

* Flower brackets { } must be used by themselves.

* Constants must be written in capitals.

* Class variables are not allowed to be called from outside the class.

The basic fundamentals must be kept in mind to work well on PHP application development. There are a number of companies going in for professionals who are experts in handling all aspects of PHP. It is important, thus to be well versed with the basics.

Companies wanting specified applications would hire PHP application developers. Thus those who wish to be hired must have a comprehensive knowledge on developing PHP applications.
