What is the equivalent in PHP for Python's pass statement?
Question:
Do you know any PHP statement that works like Python’s pass statement?
Answers:
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 )
;
When needed for readability you could use
null;
The syntax checkers and linters are becoming more and more good at signaling not useful block of codes, also when this is a voluntary action of the developer.
A native do_nothing() function would be very nice and readable sometimes.
To avoid stressing alerts from syntax checkers, I use:
echo(null);
NULL is the alternative for pass in python
$a == $b? $b = 10 : NULL;
