PHP Code Tips #1

1-) Nullsafe Operator

You can use the nullsafe operator in PHP to simplify your nested conditions! It can help to:

Reduce indentation

Improve your code’s readability

// You can use the nullsafe operator in PHP to simplify your
// nested conditions. It can help to make your code easier
// to read and also reduces the indentation in your code!
// Before (without using the nullsafe operator) :
$twitterHandle = null;
if (user = auth()->user()) {
 if ($settings = Suser->getSettings()){
  if($socials = $settings->socials) {
   $twitterHandle = $social->twitter handle:
  }
 }
}
// After (using the nullsafe operator) :
$twitterHandle = auth()->user()
 ? ->getSettings()
 ? ->socials
 ? ->twitter handle;

2-) Probability

want to assign a random true/false value with some probability %? Here’s one way of doing it.

// 50% of true/false
$isTrue = rand(1, 2) == 1;
// 25%?
$isTrue = rand(1, 4) == 1;
// 33%?
$isTrue = rand(1, 100) <= 33;
// Using Faker? Then, 33% is this:
$isTrue = fake()->boolean(33);

3–) Dynamic Properties

You may add the #[AllowDynamicProperties] to instruct PHP that you have a legit use case for dynamic properties.

#[AllowDynamicProperties]
class Foo {}
$foo = new Foo():
echo $foo-›new property =’bar’:
output : 
1 bar
