What is the difference of an `if` statement that has an {open-close} brackets, and without {open-close} brackets [closed]

Question

if statement has an open {} close brackets

  if(example){
      return example;
  }else{
      return example;
  }

if statement without open {} close brackets

  if(example)
      return example;
  else
      return example;

Can anyone explain to me about the pros and cons of using them? Thanks in advance :)

Answer 1

There is no difference in PHP or JavaScript for example; except that, with the brackets, it is easier to add instructions later without breaking your code (you are less likely to forget to add the brackets that become mandatory).
