What are the advantages and disadvantages of using the `extract()` function in PHP?

When using the `extract()` function in PHP, the main advantage is that it can simplify code by creating variables from an associative array, making it easier to access and manipulate data. However, this can also lead to potential conflicts with existing variables or unexpected behavior if not used carefully. It is important to use `extract()` judiciously and consider the potential drawbacks before implementing it in your code. 

// Example of using extract() function
$data = ['name' => 'John', 'age' => 30];

extract($data);

echo $name; // Output: John
echo $age; // Output: 30
