Frank de Jonge, author of the great EventSauce and Flysytem packages, wrote a blopost on how to use array destructuring in PHP.

In PHP 7.1 the array type has become even more powerful! An RFC was accepted (and implemented) to provide square bracket syntax for array destructuring assignment. This change to the language made it possible to extract values from array more easily.

Not mentioned in Frank's excellent post is PHP's ability to destructure arrays in foreach loops.

$members = [
	[1, 'Seb'],
	[2, 'Alex'],
	[3, 'Brent'],
];

foreach ($members as [$id, $name]) {
   // do stuff with $id and $name
}

You can even specify in which variable a value of a specific key should go:

	$members = [
	['id' => 1, 'name'=> 'Seb', 'twitter' => '@sebdedeyne' ],
	['id' => 2, 'name'=> 'Alex', 'twitter' => '@alexvanderbist'],
	['id' => 3, 'name'=> 'Brent', 'twitter' => '@brendt_gd'],
];

foreach ($members as ['twitter' => $twitterHandle, 'name' => $firstName]) {
	// do stuff with $twitterHandle and $firstName
}

Very neat!
