isset($arr[’foo’]) is not the same as in_array(’foo’, $arr)

in_array — Checks if a value exists in an array
isset($arr[’foo’]) Checks if a key exists in an array.

It’s a collection of tips, do you expect that here (or anywhere else) are still super unique tips that will improve code quality twice? I don’t think so web is just too large that we can avoid partial duplication

In that point of view you are quite right, thinking about time spending in the future, you should declare a variables even if it’s used only once. But it still less efficient than write directly variable value although that “efficient” is very small and in 99.99% that difference just imperceptible

I liked these tips, but I would disagree with one of them. I would use a variable, even if it’s only used once. The reason is that you never know when you’re going to make a change that would reuse that variable. The insignificant saving of time you might get would be swamped by the time you’d spend rewriting your script. Also, the presence of hard-coded values would tend to discourage you from thinking of reusing a value as a variable, since it would present a problem.

Just my take on it…
