Creative Ways To Make Use Of Odd And Even Numbers In PHP

By Chris Channing

Using an odd number function in PHP has allowed web designers and web developers to acheive many innovative things. Trends of this are seen, for example, in alternating color schemes, interfacing with date functions, and of course to sort and organize arrays according to a set plan. Clearly, there is great reason to learn about these functions.

It may seem somewhat far fetched, but PHP itself doesn't have a function that can determine if a number is odd or if it is even. This has led PHP developers to get creative in making their own functions that accomplish the job regardless. Whether using a simple IF statement, function, or even usign bitwise operators, there are plenty of options to undertake in order to determine if a number is odd or not.

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.

Databases are vital part of PHP, so of course odd or even number functions have their role in interfacing with them. Databases can be queried in a hefty amount of ways- and sorting the information is made possible with an odd number function in PHP. Whether building arrays from the data or outputting it directly to a table, even or odd number functions have much use.

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.

Date functions are also heavily used in PHP. Dates are used to timestamp data, give the current time, or even to calculate age restrictions (and everything in between). A date function may be paired with an odd number function in order to display information at certain times of the day, for instance. It can also be more creatively used by limiting connections to a certain website service to reduce load, hacking attempts, or several other things in addition. As can be seen, PHP developers can get quite creative in how they use such functions.

Final Thoughts

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.
