Operators and operands should use appropriate spacing to help readability
Why you should care
Itishardertoquicklyunderstandwordsthatarenotseparatedwithspaces, don’t you think? This is the same for code, especially when defining logical conditions or loops with operators (e.g. &&, ||, >=, etc.) and operands. Adding spaces before and after operators and operands will makes software easier to read.

CAST recommendations
Ideally, spaces should be added before and after each operator and operand, as shown in the example below.
Very packed IF condition (PHP):
if((!empty($foo)&&$foo>=$number)||($number<=(10*10))) { …
Same IF condition with some spaces:
if((!empty($foo) && $foo >= $number) || ($number <= (10 * 10))) { …
