Writing Function Code To Be More Readable
Last month I started writing functions in a particular way, which has made my life as a programmer much easier on more than one occasion. No matter how many comments or verbose parameter names you put in you can end up writing code that you will get lost in. The reason is simple. Lets say you had a function that took in a couple of parameters.
function myFunction($intNum1, $intNum2){
// function does something
}
Normal practice is to check the parameters to make sure that they are what you expected them to be before continuing on with the rest of the function. Let's say that we only want the numbers to be in a range. If they are not in the range the function should return false. Many programmers might start of writing something like this.
