PHP – Best Practices and Coding Guidelines

PHP is being used by 81.7% of internet, in websites that have known server side programming. Again, 98.7% of these PHP websites use the 5th version of the language. This shows that PHP 5.0 is arguable the top coding language today and the best examples lie in the form of Facebook.com, Twitter.com, Pinterest.com, WordPress.com, Wikipedia.com, Baidu.com and more.

For someone looking into a career in PHP, the future seems bright. However, it is also important to understand you are able to maintain the high code quality, PHP’s naming conventions, visual styles, and other technical settings allows developers to come up with homogeneous codes that both easy to read and maintain. The experience and personality of the coder also comes into play when differentiating a code that is “okay” and a code that is “awesome”.

Naming

Naming conventions have always been undervalued by software developers. While no one denies that having a nice name makes things easy, many opt for cryptic abbreviations, juts to save some typing. It is generally advisable to have English names for class names, comments, method names, database tables field names and variable names. It is common consensus that English is always easier to remember than special characters.

Vendor namespaces

Vendor namespaces are the base for namespaces and package keys. This provides two advantages. Firstly, there isn’t an extra requirement for a central package key registry and secondly, it allows the coder to easily integrate third party packages like Zend framework components, Symfony2 components or for that matter, any PHP 5.3+ based library.

PHP – Best Practices and Coding Guidelines

Turn on Error Reporting

Error Reporting can be a highly useful function and enabled all throughout the development phase. Among the commonly used feature here would be E_ALL, spotting all critical errors with warnings. It is mandatory that we turn on this feature before putting our code to production.

Using the DRY Approach

DRY or ‘Do not Repeat Yourself’ ensures that there is no redundant code in our scripts. Codes that violate DRY are referred to as WET solutions and are common to programmers who enjoy unnecessary typing!

WET code:

$mysql  = mysql_connect ( ‘localhost’,  ‘mysqladmin_uid’, ‘mysqladmin_pwd’ );

mysql_select_db( ‘DB_NAME’ ) or die( “Sorry !! No database selected!”);

 

DRY version:

$db_host = ' localhost ';
$db_user = ' mysqladmin_uid ';
$db_password = ' mysqladmin_pwd ';
$db_database = ' DB_NAME ';
$mysql = mysql_connect($db_host, $db_user, $db_password);
mysql_select_db($db_database);

 

Indentation / use of white space

Not just in PHP, but whatever language you may be working upon, it is necessary that the coding is properly indented and there is sufficient amount of white space wherever necessary. This helps in maintenance and enhancing the readability.

Don’t trust the user, ever!

If the application you are working on requires user inputs, make sure that it is designed to handle all kinds of possible inputs. Initializing your variables with some initial value can also be a tool against hackers, though it might not seem relevant to the business flow.

Lastly, use Cache whenever required and never resort to copying extra variables. These should keep your script sane and your application efficient.

Why Is PHP Considered A Loosely Typed Language? Top 3 Reasons For PHP’s Popularity

A Loosely typed language is a language that can create variables of different types easily. It refers to those programming scripts that do not require defining a variable type. To put it simply, while declaring a variable in these programming scripts, there is no need of defining or classifying the data type stored in them. While working with these programming scripts, you need to use a sign for each variable type(like string, integer, float, etc.) to declare them. You just need to assign a string value to the variable, to define that our variable is an integer. This is the reason why PHP is a loosely typed language. 

 

What is PHP Script?

As PHP does not require defining the variable type. As a result, you are not restricted to a limited type of data. Quite inevitably, it proves to be highly beneficial for programmers, as they enjoy optimum flexibility.

The PHP script is very much popular among programmers and developers to develop various kinds of applications. As a loosely typed language, this particular script offers golden opportunities to programmers for designing great software programs. It is the most widely used language for developing web applications. There are many factors that attract developers and users to use PHP in their applications. Here in this article, we have jotted down the reasons that make PHP so popular among all – 

1. Optimum Flexibility

While creating dynamic applications, it is the flexibility of a loosely typed programming script that renders the most useful assistance. Because of their nature, dynamic applications are quite tough to work with. Often, these applications have to determine actions based on unknown data. Using the PHP programming script proves to be the best shots, in this context. It does not enforce data types on variables, and hence offers complete flexibility in complex programming.

2. Complete Programming Liberty

In cases of strongly typed languages, the programming rules are already pre-set and pre-determined. Therefore, the programmer cannot do any changes to it as per preference. In this context, however, situations are completely different with PHP. By allowing programmers to set their own programming rules, this particular programming script offers them freedom of operation.

3. Simplicity & Cost

The PHP language is one of the most simple programming languages. Like other languages, it is bound to have its bits and bytes, but still, it is compatible to run on any system productively. Writing a PHP script is pretty much straightforward and simple as opposed to another language. It also allows programmers to write customized scripts. The cost factor also makes PHP popular! As PHP is an open-source framework, that means it is completely free to use and is fully supported by documentation.

Summing Up

PHP programming script has gained traction with ingenious programmers and has become their current favorite, but as any other script PHP also comes with its share of drawbacks. While working with PHP, programmers need to have proper knowledge, otherwise, they might create vulnerable programming codes. As a loosely typed language, PHP creates some major possibilities of errors. Say, for instance, your code needs integer input, and your variable is in a string. As the most undesired output, the entire function will break. However, it is possible to overcome this issue by creating a properly structured and organized programming code.

So now you know why PHP is a loosely typed language and why it is so popular. This programming language has various benefits and it is widely used for web application development. Want to know more details about PHP?

Reasons why PHP development is becoming so popular

According to statistics by w3techs, PHP is being used in 81.3% of all websites developed in server side programming language. It holds a market share comfortably above ASP.NET, Java, Static Files or ColdFusion. The use of PHP has been growing at a fast rate and it can unquestionably said to be the most popular programming language across the globe. But what makes PHP so intriguing? Here are some simple reasons:

6-Reasons why PHP development is becoming so popular

Simplicity

PHP programming is just like composing an English article for the computer. Aside from the fact that the language is bits and bytes, PHP is compatible to be run on any system productively. Writing a PHP script is pretty straightforward and as opposed to other language, PHP doesn’t assemble difficult coding propensities. Thus programmers can write profoundly customized scripts.

Great CMS

When the technology and internet is drifting towards dynamic content, PHP has met the need for high end CMS customization. PHP makes scripting amoebic, allowing developers to change codes as and when they will. Every site developed with PHP is highly adjustable and this opens the grounds for updates and changes that are a part and parcel of the modern market. Content management systems like Joomla, Drupal and WordPress have thus been made from PHP.

Versatile

Any PHP code can be run on all significant platforms, allowing designers to coordinate the sites in its different stages. For businesses, this would mean cost effective utilization of the current framework and working on platforms like UNIX, Linux and Windows and further an extra support to integrate Apace and MySQL.

Elastic, measurable and effective

This is clearly understood from the fact that the biggest social network, Facebook, runs on PHP. The usefulness of PHP for such a dynamic platform has also led to the creation of “Hack”, a subordinate language, to meet the changing development needs. PHP doesn’t require a server reboot to be updates as opposed to other competing languages.

Extensions and other ad-ons

PHP is the most adaptable language in the field of web development. It allows designers to create and add more updated functionalities that keep the end users hooked. Further, extensions and plugins helps new developers cope up with the programming challenges.

Highly supported

PHP is backed up by a huge library of resources and tutorials. Being open source, developers get to learn from users across the globe and this has been a defining reason why PHP is being adapted by every web developer today.

Top 6 Advantages Of Php Over Other Programming Languages 

PHP has remained one of the most versatile and pragmatic web development languages in the world today. Its range of functionalities, an amazing array of add-ins to extend functionalities, open-source nature, and tremendous online community support has made PHP a perennial favorite amongst newbies as well as established development agencies worldwide. 

So what makes PHP so popular and widely used programming language around the world? 

Well, there are many advantages that PHP has over other languages, let’s deep-dive more into details – 

The Top 6 Advantages of PHP – 

Although most web developers have a range of scripting languages, such as CGI, ASP, JSP, and Perl, most tend to favor PHP. There are several reasons why this programming language is at the forefront of website development – 

1. Easy and Simple to Learn

PHP is considered one of the easiest scripting languages. Compared to other web languages, PHP doesn’t require a manual or intensive studying. PHP syntax is logical and well-organized. Even command functions are easy to understand, as they tell the developer what function they perform. As a result, web developers find it very easy to create and optimize the application.

2. Extremely Flexible

PHP is highly flexible whether it is during an ongoing project or after completing the project. Flexibility in a scripting language is very crucial, as functionality can change anytime during the course of a project. The best part about PHP is the ability to make changes even after starting the project and this saves valuable time.

A developer does not have to write fresh codes or command functions, as changes to the existing codes and functions can be done and used.

3. Easy Integration and Compatibility

PHP is compatible with a large majority of operating systems. It can easily run on different platforms, including UNIX, Solaris, and Linux. As it can be integrated without effort with other technologies, such as Java, existing software does not require re-development. This saves time and money.

4. Efficient Performance

Depending on how the web developer codes, PHP has the potential to turn in an efficient language. It is scalable when used for writing codes and can also be used for creating a large number of applications. It is the programming language of choice when a website has several web pages.

5. Cost-Efficient

PHP is an open-source web language, hence is completely free. There is no expense involved in purchasing expensive licenses or software. It can work efficiently with different databases, such as MySQL, Apache, and PostgreSQL. The cost of developing a website using PHP is minimal.

6. Gives Web Developer More Control

Compared to other programming languages, PHP allows the website developer to have more control. Other programming languages are bogged down by long, complicated scripts, but this isn’t true for PHP. A few simple lines of code are sufficient. Furthermore, PHP allows tags, and hence, website developers can add and/or mix HTML tags, making the content extremely dynamic.

Developers don’t have to worry about placing codes in the right place when using PHP, as it is written between tags. Hence, functions and codes do not have to be written in any specific order, as long as they are within the tags.

Wrapping Up

PHP has a very helpful, active, and widespread PHP community. Also, this scripting language offers a lot of resources, such as commands, functions, and codes, which can easily be rewritten and used without incurring any cost. The ease of use, easy integration, cost efficiency, and easy access makes PHP one of the most popular server-side programming languages.
