It seems like !($width and $height) ? ...aspectRatio(); } : null can be null; however, resize() does not accept null, maybe add an additional type check?
Unless you are absolutely sure that the expression can never be null because of
other conditions, we strongly recommend to add an additional type check to your
code:
/** @return stdClass|null */functionmayReturnNull(){}functiondoesNotAcceptNull(stdClass$x){}// With potential error.functionwithoutCheck(){$x=mayReturnNull();doesNotAcceptNull($x);// Potential error here.}// Safe - Alternative 1functionwithCheck1(){$x=mayReturnNull();if(!$xinstanceofstdClass){thrownew\LogicException('$x must be defined.');}doesNotAcceptNull($x);}// Safe - Alternative 2functionwithCheck2(){$x=mayReturnNull();if($xinstanceofstdClass){doesNotAcceptNull($x);}}
Using logical operators such as and instead of && is generally not recommended.
PHP has two types of connecting operators (logical operators, and boolean operators):
Logical Operators
Boolean Operator
AND - meaning
and
&&
OR - meaning
or
||
The difference between these is the order in which they are executed. In most cases,
you would want to use a boolean operator like &&, or ||.
Let’s take a look at a few examples:
// Logical operators have lower precedence:$f=falseortrue;// is executed like this:($f=false)ortrue;// Boolean operators have higher precedence:$f=false||true;// is executed like this:$f=(false||true);
Logical Operators are used for Control-Flow
One case where you explicitly want to use logical operators is for control-flow
such as this:
$x===5ordie('$x must be 5.');// Instead ofif($x!==5){die('$x must be 5.');}
Since die introduces problems of its own, f.e. it makes our code hardly
testable, and prevents any kind of more sophisticated error handling; you probably
do not want to use this in real-world code. Unfortunately, logical operators
cannot be combined with throw at this point:
// The following is currently a parse error.$x===5orthrownewRuntimeException('$x must be 5.');
These limitations lead to logical operators rarely being of use in current
PHP code.
