What is the equivalent in PHP for Python's pass statement?

Just leave the bracket's empty...

Python has the pass word because they don't use brackets to define the body part of classes, function, and other statement. PHP doesn't have this dilemma , and therefore doesn't need something to say that a body statement is empty.

It isn't needed in PHP. The Python code:

if x == y:
    pass

Can be written in PHP by just leaving the brackets empty

if ( x == y ){
}

The same applies to other PHP constructs requiring brackets such as classes or functions.

Can't you just use a semicolon?

if ( $x == $y )
  ;
