How can one efficiently access and manipulate elements within a numerically indexed array in PHP without using extract()?

When working with numerically indexed arrays in PHP, it is important to efficiently access and manipulate elements without using the extract() function, which can lead to potential naming conflicts and security risks. Instead, you can directly access array elements using their index to retrieve or modify values. 

// Example of efficiently accessing and manipulating elements within a numerically indexed array
$myArray = array('apple', 'banana', 'cherry');

// Accessing elements
echo $myArray[0]; // Output: apple

// Modifying elements
$myArray[1] = 'orange';
print_r($myArray); // Output: Array ( [0] => apple [1] => orange [2] => cherry )
