What are the potential pitfalls of using explode() to convert a comma-separated string into an array for HTML select options?

The potential pitfall of using explode() to convert a comma-separated string into an array for HTML select options is that it may not properly handle whitespace or other characters that could be present in the string. To solve this issue, you can use array_map() along with trim() to remove any whitespace before creating the array. 

// Example comma-separated string
$options = "Option 1, Option 2, Option 3";

// Convert the string into an array using array_map() and trim()
$options_array = array_map('trim', explode(',', $options));

// Output the array
print_r($options_array);
