The popular web programming platform PHP is known for its functionality for web designers and developers alike. This holds true in providing support for odd and even number functions, which are surprisingly not always in use by web developers today. Indeed, there is much to learn in how to use such functions.

The PHP language has made many functions available within the core engine- we call these functions language constructs since they are a part of the language as a whole. But one thing that hasn’t apparently made the grade yet is a function to determine if a number is odd or even- leaving web developers to make their own functions and statements to get the results themselves. Thankfully, the process is easier than most would think.

Alternating styles in web design is the number one application of an even number function in PHP. No doubt Internet users who read blogs have seen that many blogs will alternate comment styles to make them easier to read. This is achieved in PHP by creating custom functions to determine if a comment number is even or odd, and then styling it accordingly to ensure maximum readability.

PHP and databases go hand in hand. Databases are used to store all types of information, both numbers and letters alike. But since databases can grow large in size, and literally have hundreds of columns and thousands of rows, some way to sort the information is necessary. Depending on the situation, an odd or even function in PHP will help out quite a bit.

Odd or even number functions are also used in arrays to organize data. This may only work for certain occasions, but it can help cut down on the number of arrays declared. By making odd numbers a certain value and even numbers another, you can essentially “stuff” another array inside an original array to save space.

Last but not least, we can couple a function to find even and odd numbers with the built-in date functions to achieve different results. We could, for instance, use odd and even numbers to put into algorithms to do all types of things- such as limiting the amount of login attempts a user can make in a given time period or even allowing doing something as simple as displaying data only at certain times. Whatever the case, the possibilities are endless when it comes to being creative in odd and even numbers.

Closing Comments

Web design and web development are quickly melding, as we can see with odd and even number functions in PHP. Alternating styles or even using such functions to display information at certain times during the day are two examples of the sheer power that comes as a result of the two fields of expertise.
