I have a function to populate an Object.
public static function populateObj($data) {
$obj = new Obj();
$obj->setVal1($data['val1']);
$obj->setVal2($data['val2']);
$obj->setId($data['id']);
return $obj;
}
If all values are given with the parameter $data it works fine. But if someting is missing it throws an error.
Is there a shorter and easier or better way to set null as default than this:
$data['val1'] ? $obj->setVal1($data['val1']) : $obj->setVal1(null);
...
You can merge with a default array, then $data will contain all of those keys:
$data = array_merge(['val1'=>null, 'val2'=>null, 'id'=>null], $data);
In PHP >= 7.0 you can use the Null Coalescing Operator:
$obj->setVal1($data['val1'] ?? null);
That is perhaps the fastest (fewest typed words) way to do it. Another that may be faster, if it is worth it to you is to make a class and a constructor with default values. array_pad() with array_merge() may also be worth looking at, depending on your application.
In PHP 7+ you can use ?? a.k.a null coalesce
$obj->setVal1($data['val1']??null);
$obj->setVal2($data['val2']??null);
$obj->setId($data['id']??null);
See an example here
The null coalescing operator (??) has been added (in PHP7) as syntactic sugar for the common case of needing to use a ternary in conjunction with isset(). It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.
!empty($data['val1']) ? $obj->setVal1($data['val1']) : $obj->setVal1(null)orisset($data['val1']) ? $obj->setVal1($data['val1']) : $obj->setVal1(null)
