Question

This is basic programming question. I’m a PHP developer, but this is open for everyone also.

If i use

if(something == something){ // do something }

Would that be slower to run than

if(something == something) // do something

because when you have braces the compiler checks if there might be another if statement or a loop inside it?

Answer 1

<?php
 if(1==1)
   if(2==3)
      echo 'yes 2 equals 2';
   else
      echo'2 not equals 3';
 else
  echo '1 not equals 1';
?>

O/P : ‘2 not equals 3’
Look at the above example and its output even if you dnt use braces compiler still have to check if there is another if statement.
