What potential pitfalls should be considered when integrating content from a text field in WordPress using PHP functions?

When integrating content from a text field in WordPress using PHP functions, it is important to sanitize the input to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One way to do this is by using the `sanitize_text_field()` function provided by WordPress, which removes any potentially harmful characters from the input.

// Get the content from a text field
$text_field_content = get_field('text_field_name');

// Sanitize the input using WordPress function
$sanitized_content = sanitize_text_field($text_field_content);

// Output the sanitized content
echo $sanitized_content;
