Logical if difference

Question

Recently, I came across a code like this:

if (0 === $something) { }

Is there any difference between the code above with:

if ($something === 0) { }

no, but keep in mind it is different for conditionals like `>==` and `<==` — Patrick Barr, Jul 26 '17 at 18:08
The Yoda conditions programming style’s intent is to avoid unexpected behavior. It does so by forcing a syntax error when the programmer makes a typo by using an assignment operator (=) when s/he meant to do an equality operator. if (0 == $something) // in case of type 0= $something you are safe — vaquar khan, Jul 26 '17 at 18:40

Actually there is no difference in both performance wise or in functional perspective. I can say it's a personal choice of coding style often called that as Yoda Style

In programming jargon, Yoda conditions (also called Yoda notation) is a programming style where the two parts of an expression are reversed in a conditional statement.

I prefer the later way as the first way kills the readability of code (at least for me)

No, there is absolutely no difference between the two as the if condition will check for equality between both sides.
