The Overflow Blog Podcast 254: Code Newbie talks education and community on the web. or is it wrong? However, I agree with Toto that it's best to make your functions short enough so that these conventions don't make or break your ability to figure out what's going on.So after looking at all this, I decided to go with:There are many ways to name variables (as you can see from the answers)But as a general rule, they should be named such, that it is clear from just looking at the variable itself, what it does and what it is used for, right there and not have to go through thousands of lines of code to find out - and not just for who else might have to troubleshoot later but if your code is thousands of lines long for your own good if you yourself have to troubleshoot laterAND WHATEVER NAMING CONVENTIONS YOU CHOOSE BE CONSISTENT THROUGHOUT YOUR CODE - this cannot be iterated enough :)That way no matter where I look at the variable in any part of the code (HTML, PHP, etc.) of the class/package they are used in. I know...If I instead just had named it $tnVid I might personally have a vague notion of what it is but someone else looking at will have no idea that tn stands for (t)humb(n)ail, etc.Thanks for contributing an answer to Stack Overflow! If your package needs to define global variables, their names When the "test" works, I often don't take the time to rename the variable wherever it's been listed.As for parameters specifically, I've never used the P notation.

PHP does not yet support truly-enforceable private namespaces Is there a naming convention or maybe some guideline on how to name function parameters?That way I'll always know which variables were passed as parameters. Prefix constant names with the uppercased name (This one's PHP, but it should be applicable to most programming languages)Is there a better way to do this or is it probably best to just avoid such naming schemes?If you need this, it means that the code written is not readable enough (functions/methods too long), cryptic variable/function names, bad OO practices, shortcuts, code debts, etc. That scope may be vendor-level, package-level, class-level, or method-level.
