What are the best practices for handling strings in PHP arrays?

When handling strings in PHP arrays, it's important to ensure proper sanitization and validation to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One way to do this is by using functions like `htmlspecialchars()` to escape special characters in the strings before storing them in the array. Additionally, it's a good practice to trim and validate user input to ensure data integrity. 

// Example of sanitizing strings before storing them in an array
$userInput = "<script>alert('XSS attack');</script>";
$sanitizedInput = htmlspecialchars(trim($userInput));

$array = [];
$array['user_input'] = $sanitizedInput;

var_dump($array);
