PHP语法缩短if语句

Question

Disclaimer : the following is a bad practice (but it would be useful in a very, very specific use)

Is there a way to shorten (in a not-so-nice-way-but-shorter) if statements : instead of :

if(5 == $foo){
   $b = 98;
   $c = 98 * $otherVariable;
   //do something complex
   doSomethingElse($b, $c);
}

This example would become shorter, even if it is formatted by an IDE. It would become something like that (but this does not work):

(5 == $foo) && { $b = 98;
   $c = 98 * $otherVariable;
   //do something complex
   doSomethingElse($b, $c);}

Answer 1

I suggest, you should opt for better readable code, but still if you want to do something different, you may go through below :

($foo == 5) && doSomethingElse(98, 98*$otherVariable);

OR

PHP Ternary Operator

($your_boolean) ? 'This is  true' : 'This is false';

You can rewrite your if statement like below :

($foo == 5) ? doSomethingElse(98, 98*$otherVariable) : "";

// little shorter but not better readable
($foo != 5) ? :  doSomethingElse(98, 98*$otherVariable);

Test Results:

$ cat test.php
<?php
function aa(){ echo "123
"; }

$foo = 5;

// this will not call aa()
($foo == 4) && aa()  ;

// this will call aa()
($foo == 5) && aa() ;
?>

$ php test.php
123
