Is there a preferred way to name variables in PHP? [closed]

Question

I am fairly new to PHP and I was wondering if there was a standard convention to name php variables. I'm used to using camel case when naming variables, but I see a lot of underscores in PHP examples.

Is there a standard naming convention that most people use for PHP?

$buildingHeight OR $building_height

Answer 1

It is really all about your preference in the case you mentioned. I prefer using underscore because it helps me read the variables better when scanning through the code, but ultimately it's up to you.

Other important things to note about PHP variables:

• Must start with a letter or underscore (_).

• May only be composed of alpha-numeric characters and underscores a-z, A-Z, 0-9, or _ .

I hope this helps!
