The extract Function
The extract function imports elements
of an associative array into variables. The names of
the variables will be the keys of the associative
array.
Syntax
extract(array &$array, int $flags = EXTR_OVERWRITE, string $prefix = ""): int
Example
Let's extract variables from the array:
<?php
$arr = ['a' => 1, 'b' => 2, 'c' => 3];
extract($arr);
echo($a);
echo($b);
echo($c);
?>
Code execution result:
1
2
3
