Should I Use Parentheses When Instantiating a Class in PHP?

PHP Class Instantiation: Parentheses or Not?

In PHP, the act of creating an instance of a class is known as instantiation. When doing so, some developers may wonder if parentheses following the class name are required.

Parentheses in Class Instantiation

Previous knowledge suggests that parentheses are optional when instantiating a class without constructor parameters. For example:

$foo = new bar;
$foo = new bar();

Both statements result in the same output, leading to the assumption that parentheses are merely a matter of personal preference.

Significance of Parentheses

However, there is no inherent significance to the parentheses themselves. They serve no functional purpose and do not alter the behavior of the code.

Choosing to Use or Not Use Parentheses

As such, the choice of whether or not to use parentheses is purely a matter of coding style and personal preference. It is recommended to adhere to coding conventions or the established style within your project for consistency.

Personally, many developers prefer to omit parentheses as they view them as unnecessary clutter in the code.

Conclusion

While parentheses may not be strictly required for class instantiation in PHP, their usage depends on personal preferences and established coding conventions. Their presence does not affect the functionality of the code, making it ultimately a stylistic choice.
