Assignation
Assignation, sometimes misspelled assignement, refers to the process of assigning a value to a variable. It is a fundamental concept in programming that allows storing and manipulating data.
The main operator of assignation is =. There are secondary operators, such as +=, *=, ??=, … which are called short assignation: they apply a specific operation while assigning.
Finally, there are some inherent assignations: foreach() loops, method calls and list() operator perform assignations without an explicit operator.
<?php
$a = 'b';
// $c is assigned by
foreach([1, 2, 3] as $c) {}
echo $c; // $c is 3
// list call that assigns values
[$a, $b, $c] = ['a', 'b', 'C'];
?>
