Introduction

PHP is an open-source scripting language that can be used to create dynamic websites and web applications. As a programmer, writing clean and well-organized code is an essential aspect of developing programs. Writing attractive and readable code helps make debugging, testing, and maintenance more manageable. In this article, let's look at how we can write PHP code that is more aesthetically pleasing.

Naming Conventions

Choosing the proper naming convention for variables, functions, and classes is the first step when writing clean code. When naming variables or functions, we should use descriptive and meaningful names that can give the reader an idea of what we intend to accomplish. We should also use camel case for functions and variable names, which means we should start with a lowercase letter and capitalize every word afterward. For example:

```php
$userDetails = getUserDetails($userId);
```

When naming classes, we should use Pascal case, which means we should start with a capital letter and capitalize every word afterward. For instance:

```php
class UserRegistration {
// ...
}
```

Structure and Formatting

Another vital aspect of writing clean code is to format the code to make it more readable. Let's explore a few formatting techniques that can help us write better-structured PHP code.

Indentation

Indentation makes code easier to read and comprehend, and as a result, it's considered a best practice. We should use four spaces for each level of indentation, as shown below:

```php
if($userRole === 'admin') {
// Admin permissions...
} else {
// Regular user permissions...
}
```

Spacing

Using space correctly is essential for writing neat code. It makes code more readable and easy to understand for other developers. We should use spaces between operators, parameters, and other significant elements in our code:

```php
function addNumbers($num1, $num2) {
$result = $num1 + $num2;
return $result;
}
```

Comments

Comments make code more readable by explaining the purpose and functionality of specific sections of code. We should explain the purpose of a function, method, or code block with comments. Our comments should be brief and explicit, explaining the code's logic or purpose.

```php
/**
* Function to calculate the area of a circle
*
* @param int $radius
* @return float
*/
function calculateAreaOfCircle($radius) {
$area = pi() * ($radius ** 2);
return $area;
}
```

Conclusion

In conclusion, writing attractive and neat PHP code requires a mixture of proper conventions, well-structured code, and white space management. These tips can help us write better-looking code that is more comfortable to read and maintain. Ultimately, well-written code saves time and frustration in the long run, making it worth the effort to follow these best practices.
