How can PHP developers handle strings with whitespace when using functions like explode to extract data and create arrays?

When dealing with strings that contain whitespace, PHP developers can use the trim() function to remove any leading or trailing whitespace before using functions like explode to extract data and create arrays. This ensures that the whitespace does not interfere with the data extraction process. 

$string = "   Hello, World   ";
$trimmedString = trim($string);
$array = explode(",", $trimmedString);

print_r($array);
